Japan's ERP market: how Japanese vendors, SIer subcontracting chains and the Invoice System shape it – and what sets it apart from Germany

Japan is the economy that German mid-sized companies are most likely to enter with a familiar picture in mind – industry, quality, family businesses with centuries of history – only to discover that the ERP market reflects almost none of it. In the mid-market, Japanese systems lead whose names hardly anyone outside Japan knows; SAP is strong, but above all in the large-enterprise segment. Invoices need a state registration number, but no structured data format. And a considerable share of core software is not created as a package but as commissioned custom development.

This page describes how the Japanese ERP market actually works – researched with Japanese-language sources (analyst houses, government agencies, association and user studies, vendor IR reports) and interpreted from a German perspective. At the end you will find the ten biggest differences from the German ERP market. The German comparison figures come from our ERP statistics and the ERP market shares; every Japanese figure is attributed with publisher and reference year, and where Japanese sources supply no figure, we say that too.

Country

Japan (日本)

ERP software market volume

depending on scoping 168.44 billion yen (package licences, Yano Research, 2024), 255.8 billion yen (vendor revenue from packages plus SaaS, ITR, FY2024) or 342.69 billion yen (shipment value of core application packages, Deloitte Tohmatsu MIC, FY2024)

Share of the global market

no analyst source states Japan's share; a reliable figure is not available. the three market figures correspond to roughly 1.1 to 2.3 billion US dollars (2024 rate: approx. 151 yen to the US dollar)

Cloud share

65 % of market volume, of which pure SaaS around 22 %; over 70 % expected for 2026 (Yano Research, 2024). By deployment mode among users: on-premises 49.2 %, SaaS 32.8 %, IaaS/PaaS 21.1 % (Keyman's Net, 2024)

Defining vendors

large enterprises: SAP, Works Applications (HUE), Fujitsu, Oracle, Biz∫ · mid-market: SMILE, GLOVIA, OBIC7, Bugyo, GRANDIT, SuperStream-NX, EXPLANNER, SAP Business One, Dynamics 365 Business Central · small enterprises: Yayoi, freee, Money Forward

Tax system

consumption tax 10 % (7.8 % national plus 2.2 % local), reduced rate 8 % for food and subscription newspapers (National Tax Agency, since October 2019)

What the Japanese ERP market is NOT — scoping

• Not a SAP country like DACH: in the mid-market Japanese systems lead, and according to the Nork survey of 2025 switching intentions run in favour of Japanese vendors.
• Not an e-invoicing market in the German sense: the Invoice System governs registration and invoice content, not the data format; Peppol is voluntary, paper and PDF remain permissible.
• Not a pure packaged-software market: in core business, externally commissioned custom development is the most common procurement route at just under 40 percent (IPA, 2025).
• Not a consistently measured market: three analyst houses arrive at values that are more than a factor of two apart; market shares exist only as installation or panel shares.

Market overview: one market, measured three times over

Anyone asking how big the Japanese ERP market is gets three answers. Yano Research puts the market for ERP package licences at end-customer prices at 168.44 billion yen for 2024, ITR adds up vendor revenue from packages and SaaS and arrives at 255.8 billion yen, and Deloitte Tohmatsu MIC measures the shipment value of core application packages and lands at 342.69 billion yen. At the 2024 annual average rate of around 151 yen to the US dollar, that corresponds roughly to 1.1, 1.7 and 2.3 billion US dollars respectively – against the 3.62 billion US dollars that Mordor Intelligence assumes for the German market in 2026 (see ERP statistics). Even the widest Japanese definition stays below that. It is not a clean size comparison, because the definitions diverge – but it is an indication that a great deal of demand runs through project business rather than through licences.

Two movements shape the figures. First the shift to cloud: ITR sees the package business growing by only 3.5 percent in 2024, SaaS by 28.2 percent, and forecasts an annual decline of the package business of 0.9 percent through 2029 alongside 20.0 percent SaaS growth. Second the uneven distribution by size: ERP usage falls from 56.8 percent among companies between 5 and 50 billion yen in revenue to 14.0 percent below 0.5 billion yen (Nork Research, 2025); Keyman's Net arrives at 41.1 percent across all sizes for 2024, with 10.3 percent below 100 employees. The German Eurostat values for 2025 stand at 43.5 percent of all companies with ten or more employees (small 37.5, medium 67.7, large 89.4 percent). The averages are similar, but the Japanese curve is flatter in the lower mid-market; and it is precisely there that Nork puts replacements and new implementations at 536.70 billion yen over roughly three years.

Vendor landscape: Japanese houses, foreign brands and a consortium

The Japanese ERP market cannot be sorted by revenue classes, because there is no revenue statistic – only installation shares from user surveys. In the Nork survey of 2025 among companies with less than 50 billion yen in revenue (516 responses on the main system), SMILE from Otsuka Shokai leads with 15.1 percent and GLOVIA from Fujitsu with 14.0 percent, ahead of SAP ERP with 12.0 percent; behind them follow SAP Business One (7.9 percent), Bugyo V ERP (5.6 percent), OBIC7 (5.2 percent), Microsoft Dynamics 365 (4.7 percent) as well as Money Forward Cloud ERP, EXPLANNER and Biz∫.

These figures need to be read with caution. An older Nork analysis from 2023 quoted 37.0, 28.8 and 26.0 percent for the same three leading products – a level whose reference base cannot be reconstructed. A panel survey by the comparison portal BOXIL among 1,793 people involved with ERP (March 2025), by contrast, is led by Money Forward Cloud ERP (13.55 percent) and Dynamics 365 Business Central (7.98 percent). At Keyman's Net (241 responses, March 2024), on the other hand, 29.3 percent named SAP ERP (ECC 6.0) and 23.2 percent S/4HANA. A reliable market share statistic by revenue or unit numbers is not publicly available for Japan – unlike in Germany, where our market share estimates put SAP at around 38 percent.

The Japanese houses: OBIC, OBC, Otsuka Shokai, Works Applications

OBIC (Tokyo Stock Exchange, 4684) is the most profitable address in this group: 135.21 billion yen in revenue in the financial year to March 2026 on 88.82 billion yen of operating profit – a margin of 65.7 percent; as early as the financial year to March 2025, OBIC reported 31 consecutive years of profit growth. The house sells OBIC7 exclusively direct, without a partner channel and without a price list. OBC, maker of the Bugyo series, is the volume vendor: 860,000 cumulative installations by its own account (as of 27 August 2026), 21,800 mid-sized customers and a contract continuation rate of 99.4 percent on 51.4 billion yen in revenue – distributed exclusively through partners. Otsuka Shokai (4768) is a multi-vendor dealer and system integrator with its own ERP: 1,322.79 billion yen in group revenue in 2025; the SMILE series has existed since 1979. Works Applications is the Japanese representative in the large-enterprise segment: 11.5 billion yen in revenue in the financial year to June 2025, 500 corporate groups as customers – and, by vendor revenue in ITR's 2026 market view, the number one in financial ERP for companies from 100 billion yen in revenue upwards.

Cloud-native challengers from accounting

Below the established houses, a group of cloud-native vendors is growing out of accounting towards ERP. freee (4478) generated 33.27 billion yen in revenue in the financial year to June 2025 on 34.39 billion yen of annual recurring revenue and 606,533 paying corporate customers; the step into cloud ERP followed in 2023, and according to Nikkei xTECH the price level is around 2 to 3 million yen a year – one to two orders of magnitude below SAP or Oracle. Money Forward (3994) reported annual recurring revenue of 28.654 billion yen in its corporate business for the third quarter of the financial year to November 2025. Yayoi leads the market for cloud accounting among sole proprietors with over 3.5 million registered users: in the survey by MM総研 (March 2025, n = 22,575), Yayoi came to 55.4 percent ahead of freee (24.0 percent) and Money Forward (14.3 percent); for 2026 Yayoi itself quotes 54.0 percent and an eleventh consecutive year in first place.

Corporate system houses, a consortium and the foreign brands

One peculiarity is that the large IT groups are system integrators and ERP makers at the same time. Fujitsu quotes over 20,000 cumulative installation sites for the GLOVIA family, NEC over 30,000 companies in 50 years for EXPLANNER; both additionally claim market leaderships that are not backed by a publisher source – we do not repeat them. Alongside these, GRANDIT represents a model with no German counterpart: a consortium ERP developed jointly by several system houses and distributed through more than 70 partners, with over 1,500 implementations; in finance and HR, SuperStream-NX from the Canon ITS group is widespread. Foreign vendors are positioned differently than in Europe: SAP dominates the large-enterprise segment, Dynamics 365 runs through partners such as Hitachi Solutions, and Oracle NetSuite has been active since 2005, quotes 37,000 customers worldwide but no figure for Japan. The momentum at Nork is revealing: planned minus installed shares produce plus 5.0 for Bugyo and plus 3.2 percentage points for OBIC7, and minus 4.6 for Dynamics 365 and minus 4.0 for Money Forward Cloud ERP.

Industries: manufacturing as the largest block, construction as its own universe

In manufacturing, production management systems are run as SaaS by 36.9 percent and on PaaS or IaaS by 19.2 percent, according to a survey by Kyocera Communication Systems (2024, n = 355). A universe of its own is construction: in Japanese software directories, construction ERP forms a separate category with around twenty systems. The drivers are site-based project cost accounting, quantity surveying, the administration of joint ventures and a separate accounting standard; no reachable source publishes a market size for this segment, and none for medicine and care either.

The mid-market in Japanese: capital thresholds instead of a question of ownership

The German concept of the Mittelstand is qualitative: under the definition of the Institute for Mittelstand Research in Bonn, a company belongs to the Mittelstand if it embodies the unity of ownership and management, regardless of size. Japan defines quantitatively and by sector: under Article 2 of the Basic Act on Small and Medium Enterprises, a company counts as an SME if it falls below one of two thresholds – in industry 300 million yen of share capital or 300 employees, in wholesale 100 million yen or 100 employees, in retail 50 million yen or 50, in services 50 million yen or 100. A reliable total number of Japanese SMEs could not be verified from the reachable primary sources; we therefore do not state one. For Germany it is unambiguous: 3.443 million SMEs correspond to 99.2 percent of all companies.

What is documented is the intermediate category 中堅企業 created in 2024 – companies with up to 2,000 employees that are no longer SMEs. In May 2024 Teikoku Databank counted exactly 7,749 such firms: around 0.53 percent of all companies, but 15.68 percent of domestic revenue. Since 2019 their number has fallen by 820, because 973 firms reduced their share capital during the coronavirus period and switched back to SME status – a manoeuvre the German concept of the Mittelstand does not know, because it does not hang on capital.

Where the German Mittelstand carries the unity of ownership and management as a defining feature, in Japan it is currently dissolving. The successor vacancy rate stood at 50.1 percent in 2025 – falling for the seventh year in a row, but still around 138,000 companies without a settled succession. More telling is the form: 36.1 percent of handovers took place via an internal promotion, only 32.3 percent within the family; for the first time, more than 40 percent of designated successors are not related. At the same time, 46,708 Japanese firms have existed for over a hundred years, a rate of 3.11 percent. For system selection this means: grown processes and, at the same time, a management generation that increasingly comes from outside.

The state of digitalisation lags behind Germany. The IT promotion agency IPA compares directly in its study on DX trends 2025: 77.8 percent of Japanese companies run digitalisation initiatives, but the spread ranges from 96.1 percent among those with 1,001 or more employees to 46.8 percent among those with up to 100. On success, Japan trails the USA and Germany at just under 60 percent against over 80 percent; among large enterprises it is 64.2 against 92.0 percent in Germany, and on defined success metrics 27.4 against 82.7 percent. In the survey by the SME organisation among 1,000 SMEs, 18.9 percent are active and 20.2 percent are evaluating; the biggest obstacle is seen as a lack of IT staff (28.3 percent).

Regulation and compliance: what an ERP has to do differently in Japan

Consumption tax and the Invoice System

Japan has, unlike the USA and similarly to Germany, a value added tax. Since October 2019 the standard rate of 10 percent has been composed of 7.8 percent national and 2.2 percent local tax, the reduced rate of 8 percent of 6.24 and 1.76 percent. The break with European habits is the Invoice System of 1 October 2023: the input tax deduction requires a qualified invoice with six mandatory details, among them the issuer's registration number – a “T” plus 13 digits, identical with the corporate number for stock corporations. For this the tax agency operates a publication site with a web interface through which ERP systems can reconcile their supplier master data. As of 30 September 2023, around 3.78 million registrations had been issued; the agency does not publish a current figure.

For purchases from unregistered small businesses a transitional rule applies that has to be stored in the system as a time-dependent percentage per supplier: 80 percent notional input tax deduction until 30 September 2026, then 50 percent until 2029, and nil thereafter – so the changeover is imminent. Technically the trickiest point is rounding: the tax agency permits exactly one rounding of the tax amount per qualified invoice and per tax rate; line-by-line rounding with subsequent summation – the standard in many European-influenced systems – is not permitted for the invoice statement, while the rounding method itself is free.

Electronic retention and digital invoicing – two separate topics

The Act on Electronic Bookkeeping Retention covers three areas – electronically created books, scanned paper vouchers and electronically exchanged transaction data – but only the third is mandatory, since 1 January 2024 and after a two-year grace period expired. For authenticity, one of four measures suffices, among them simply an internal procedural rule; a time stamp is not compulsory. Companies with up to 50 million yen in revenue are exempt from the search requirements. The tax deadlines are shorter than the German eight to ten years: seven years, ten with a loss carry-forward. The German debate about GoBD-compliant procedural documentation has its counterpart here; added to it is the voluntary JIIMA product certification, which on 21 August 2026 listed exactly 167 approved products.

Strictly to be distinguished from this is the digital invoice. Japan's Digital Agency has been the Japanese Peppol Authority since September 2021. There is no obligation to use it – the requirements of the Invoice System can still be met with paper or PDF. As of 24 April 2026 the Digital Agency lists eleven certified Japanese service providers; secondary sources quote 15 (2022), 36 (2024) and 33 (2025) respectively for the wider circle that also includes foreign providers – a contradiction we cannot resolve. Nobody publishes figures on the level of adoption. Germany, by contrast, has required the receipt of structured formats under EN 16931 since 1 January 2025 and their dispatch from 2027 and 2028 respectively – in practice via XRechnung and ZUGFeRD – but knows no registration requirement. Japan requires registration and defines the invoice content, but leaves the format to the parties involved – the e-invoice in the European sense is not a legal concept there.

Financial reporting: J-GAAP as the rule, J-SOX as the control framework

Japan never made IFRS mandatory. According to an analysis by the Tokyo Stock Exchange as of 30 June 2025, 300 companies apply IFRS – 7.9 percent of the 3,803 domestic listed companies, but ones that account for 49.8 percent of market capitalisation. Parallel ledgers are therefore a group topic, not one for the broad mid-market (background under IFRS vs. HGB). For listed companies J-SOX is added, the obligation to file an internal control report with an auditor's attestation; the financial regulator revised the standards in 2023, and the new versions apply from April 2024. Two changes affect the ERP directly: controls over outsourced IT services – that is, cloud and SaaS operation – belong within the audit scope, and prior-year assessments may only be reused on a risk basis. The commercial retention obligation under the Companies Act could not be verified.

Data protection: its own law, mutual recognition with the EU

Japan has a uniform national data protection law and, for German companies, a comfortable addition: since 23 January 2019 the EU and Japan have mutually recognised their data protection levels as adequate, so personnel data from a European HR or ERP system may flow to the Japanese subsidiary without standard contractual clauses. Even so, the transfer is not unrestricted: for EU data, supplementary rules of the data protection commission apply, with stricter purpose limitation and restrictions on onward transfer to third countries. The 2020 amendment introduced a reporting obligation for data breaches and a maximum fine of 100 million yen. A further amendment was promulgated on 17 July 2026; its contents are available only as a PDF and could not be verified.

Payroll and social contributions: five contribution types, three assessment logics

Japanese payroll is the reason why many German subsidiaries do not run it in the group ERP. Health, nursing care and pension insurance are assessed via a 32-tier standard remuneration scale, unemployment insurance as a percentage of wages, and accident insurance at a sector rate. In 2025 the health insurance rates of the nationwide fund differ by prefecture between 9.44 percent in Okinawa and 10.78 percent in Saga; pension insurance has stood unchanged at 18.3 percent since September 2017. Two features have no German equivalent: the year-end adjustment, in which the employer recalculates the annual income tax in December and thereby replaces the tax return for most employees, and the resident tax: ten percent on the previous year's income, reported to every single municipality of residence and remitted separately per municipality. A company with employees from fifty municipalities runs fifty payment streams. No reachable source publishes a rate for outsourced payroll.

Payments, subcontracting law and customs

The paper bill of exchange is being phased out: the banking associations want to bring the number of bills and cheques exchanged down to zero by March 2027. The volume fell from around 440 million items (1979) to 19.67 million (2024), while the electronic receivables of the Densai network rose to 8.02 million transactions. Classic modules for bill receivables thereby lose their basis; what is needed instead are Densai interfaces and transfer files in the Zengin format, which permits only half-width characters – it is the XML standard ZEDI that first lifts that limit. Since 1 January 2026 the Act on Ensuring Fairness in Contract Awards to Small and Medium Enterprises has additionally applied: payment due at the latest 60 days after receipt of performance, default interest of 14.6 percent a year and a ban on payment by bill of exchange. The supplier master therefore needs capital and headcount data for classification; payment terms beyond 60 days and bill payments must be blocked in the system.

In foreign trade the situation is comfortable compared with Europe: the Economic Partnership Agreement between the EU and Japan has applied since 1 February 2019 and, according to JETRO, dismantles around 99 percent of tariff lines on the EU side and around 94 percent on the Japanese side. What matters is the form of proof: origin is evidenced exclusively by self-declaration of the exporter or manufacturer – third-party certificates such as chamber certificates of origin are not provided for, which shifts the burden of proof into the master data. Far more unsettled is US business: since 7 August 2025 a tariff rate of 15 percent applied; on 20 February 2026 the Supreme Court of the United States ruled the tariffs based on the emergency powers act unlawful, they were suspended from 24 February 2026 and replaced by a temporary tariff (total burden roughly 13 percent according to JETRO), while the tariffs on vehicles (15 percent) and on steel and aluminium (50 percent) remained. Landed cost calculation and refund tracking therefore have to be versioned – how strongly that shapes American ERP operations is described on our country page on the USA.

Implementation, partners and prices

The multi-tier subcontracting chain

The most striking structural peculiarity of the Japanese IT industry is the multi-tier subcontracting chain. In 2022 the competition authority surveyed around 21,000 software companies and found constellations reaching down to the sixth tier. Billing is by person-months, with margins of 20 to 60 percent accruing at each link of the chain. Behind this lies a different distribution of staff than in Europe: according to the Digital Agency, around 30 percent of IT specialists work at user companies and around 70 percent at IT vendors. That explains why, in core business, externally commissioned custom development is the most common procurement route at just under 40 percent, while in Germany in-house development, external development and standard software each account for around 30 percent (IPA, 2025).

Sales models: direct, through partners, in a consortium

The Japanese vendors have very different models among themselves. OBIC sells OBIC7 exclusively direct, support included – at an operating margin of 65.7 percent, an indication of how much value creation otherwise sits in the channel. OBC distributes the Bugyo series only through partner system houses, GRANDIT is distributed by a consortium through more than 70 partners, and Fujitsu, NEC and NTT Data are makers and prime contractors at the same time. Anyone looking for a system house from Germany therefore has to establish first whether the target product is sold through partners at all.

Project costs, prices and contract forms

User studies along the lines of the German Trovarit surveys do not exist for Japan; what is available are ranges from consulting and trade portals, which we label as such. For mid-sized companies the trade portal Cloud ERP Jissen quotes several hundred thousand up to 5 million yen a year for cloud solutions at departmental scope and 5 to several tens of million yen company-wide; for on-premises, 5 to 20 million yen at departmental scope and 30 million yen upwards company-wide, with maintenance rates of 15 to 22 percent of the licence a year. An implementation guide for smaller companies quotes a project duration of six months to a year and a half. In Germany, Trovarit quotes around 4,400 euros of investment per ERP workstation, roughly twelve months of project duration and maintenance rates of 12 to 25 percent (details in the ERP statistics and in the ERP cost overview). The maintenance ranges are therefore close to each other; comparable costs per workstation do not exist for Japan.

On running prices, the market overview by BOXIL is the most usable reference: cloud core systems accordingly cost 12,000 to 18,000 yen per user and month, with up-front costs between 0 and 100,000 yen. A second finding from the same survey is telling: 15 out of 15 large vendors examined quote no list prices. One of the few exceptions is OBC, which openly tiers its cloud financial accounting product Kanjo Bugyo i Cloud between 7,750 yen a month with no up-front cost and 28,000 yen a month plus 70,000 yen of up-front cost. We deliberately refrain from converting into euros: we only have the yen-dollar rate of the Bank of Japan, which fluctuated by more than twelve percent between September 2024 (142.38 yen to the US dollar) and August 2026 (159.57 yen).

Subsidies as a price factor

One element with no German counterpart is state project funding. The former IT implementation programme has been called the digitalisation and AI adoption subsidy since 2026: for solutions covering at least four business processes – that is, every ERP – the standard framework provides 1.5 to 4.5 million yen at a funding rate of one half, or two thirds for businesses close to the minimum wage. The manufacturing subsidy scales by headcount from 7.5 million yen (up to five employees) to 25 million yen (from 51 upwards), tied to conditions on value-added and payroll growth of 3.0 and 3.5 percent a year respectively. On top of that comes the state DX certification, which is valid for two years and brings a discounted loan from the state development bank (1.10 instead of 1.75 percent, as of May 2025); the authority does not publish an absolute number of certified companies.

Skills: the 790,000 gap

The best-known figure in the Japanese IT debate comes from a METI study: by 2030 up to 790,000 IT specialists could be missing, around 450,000 in the middle scenario. In companies the shortage is a reality: 85.1 percent report a quantitative shortage of digitalisation staff according to the IPA survey. The analysis by the recruitment services provider doda covering around 600,000 people quotes a mean annual salary of 6.01 million yen for IT consultants and 4.35 million yen for systems developers. An ITR survey of 829 companies with 300 or more employees from May 2026 records the strongest increases in contract rates among more highly qualified developers and consultants, but quotes no absolute person-month rates – a gap that cannot be closed from public sources.

Trends 2025/2026: the SaaS tipping point, SAP 2027, AI agents and a weak yen

The market is tipping from package to SaaS right now – but not everywhere. For 2024 ITR sees only 3.5 percent growth in the package business against 28.2 percent in the SaaS business, and forecasts an annual decline of the package business of 0.9 percent through 2029 alongside 20.0 percent SaaS growth. Yano puts the cloud share of market volume at 65 percent for 2024, expects over 70 percent for 2026 and names the fit-to-standard stance and expiring maintenance contracts as the drivers. Remarkable is the counter-finding from Nork: in the mid-market, the share of classic on-premises packages as the main system rose between 2020 and 2024 from 36.0 to 41.7 percent, while SaaS only went from 12.8 to 13.8 percent. Cloud in Japan therefore often means infrastructure cloud, not SaaS – a pattern that resembles the German preference for private cloud, where according to Trovarit around 40 percent falls to private and a good 20 percent to public cloud (context under cloud ERP vs. on-premises).

The SAP 2027 problem is a topic of its own in Japan. Standard maintenance for SAP ECC 6.0 ends at the end of 2027, extendable against a two percent surcharge until the end of 2030. Japanese trade media put the number of SAP ERP user companies at around 2,000, a consulting source at 10,000 – we stick with the lower, repeatedly cited order of magnitude and mark it as an estimate. In April 2022 the user group JSUG counted around 580 member companies and thus about 30 percent of users. Its survey shows a clear trajectory: the share with S/4HANA in use rose from 22.3 percent (2021) to 55.2 percent (2025); on the licence model, 49.1 percent opted for RISE, 9.3 percent for GROW and 26.9 percent still for on-premises. Around 85 percent are not considering any non-SAP product – so the willingness to switch is lower than the German debate about SAP alternatives would suggest. The bottleneck lies with the consultants: one trade analysis estimates that only around a hundred firms in Japan are able to support S/4HANA implementations.

Artificial intelligence is coming first from the cloud accounting houses. While in the USA the large ERP vendors occupy the topic, in Japan the concrete product announcements of 2026 came predominantly from freee and Money Forward: freee released an AI assistant in June and an agent hub for tax firms in August; Money Forward presented an audit agent for group financial statements and an AI-supported payroll service in August, and automated lease contract administration in September. In the broad market, use remains limited: JUAS counts around 40 percent of large user companies that have introduced, piloted or prepared generative AI, and over 90 percent among companies from one trillion yen in revenue upwards, with the fear of confidential information leaking out as the main risk. In small and medium-sized enterprises the adoption rate is 20.4 percent, with a further 18.6 percent evaluating; 87.0 percent pursue the goal of process efficiency (context under artificial intelligence in ERP).

A weak yen, rising wages, consensus-driven decisions. In the Bank of Japan's monthly averages the yen moved between 142.38 to the US dollar (September 2024) and 160.93 (June 2024) and stood at 159.57 in August 2026 – meaning more expensive foreign software. In the JUAS survey the indicator for IT budget development reached 42.3 points in 2024, its highest value in ten years, and the most frequently named reason for budget increases was, at 43.5 percent, the combination of yen weakness, rising staff costs and price increases by vendors; renewal of the core system was named by 40.1 percent. At the same time, around three quarters of the IT budget still flows into ongoing operations – the background to the legacy debate, for which METI's 2018 report had forecast annual damage of up to 12 trillion yen from 2025. Decisions are taken through the Ringi procedure: a written application circulates through all the departments concerned and is signed off by each – Japanese selection guides recommend planning for that time. In dealing with the standard, the market is more divided than the fit-to-standard rhetoric suggests: according to Nork, depending on the revenue class only 15.0 to 28.2 percent intend to adapt their processes to the product (pointers in the guide to ERP selection and under ERP implementation).

The 10 biggest differences between the Japanese and the German ERP market

1. The market is smaller than expected – and measured three times over. Depending on the scoping, the volume is 168.44 billion yen (Yano), 255.8 billion yen (ITR) or 342.69 billion yen (MIC), so roughly 1.1 to 2.3 billion US dollars – against 3.62 billion US dollars for Germany (Mordor Intelligence, 2026). Even the highest Japanese value stays below that.
2. In the mid-market, Japanese systems lead, not SAP. By installation share, SMILE (15.1 percent), GLOVIA (14.0 percent) and SAP ERP (12.0 percent) are in front (Nork Research, 2025); in Germany, SAP alone comes to around 38 percent according to our estimates. The momentum from planned minus installed systems falls in favour of Japanese vendors – Dynamics 365 comes last at minus 4.6 percentage points.
3. An Invoice System instead of an invoice format. Since October 2023 Japan has required a state registration number for the invoice issuer and six mandatory details, but prescribes no data format; Peppol is voluntary. Germany, conversely, has required the receipt since 1 January 2025 and the dispatch from 2027 and 2028 respectively of structured formats under EN 16931, but knows no registration.
4. Tax rounding and the input tax transition are system topics with no German counterpart. The Japanese tax agency permits exactly one rounding per invoice and tax rate – the line-by-line rounding customary in European systems is not permitted for the invoice statement. Added to that is a time-dependent input tax rate for purchases from unregistered small businesses: 80 percent until 30 September 2026, 50 percent thereafter, and nil from 2029.
5. Electronic retention is regulated differently than under GoBD. Mandatory since 1 January 2024 is only the electronic retention of electronically received transaction data; for authenticity an internal procedural rule suffices, a time stamp is not compulsory, and companies with up to 50 million yen in revenue are exempt from the search requirements. At seven years, and ten with a loss carry-forward, the deadlines are shorter than the German eight to ten.
6. “Mittelstand” is a capital threshold, not a question of ownership. Japan defines SMEs via sector-dependent thresholds on capital or headcount and in 2024 created an intermediate category up to 2,000 employees that covers 7,749 firms and 15.68 percent of domestic revenue. Germany defines the Mittelstand via the unity of ownership and management: 3.443 million SMEs, or 99.2 percent of all companies.
7. Software is commissioned, not bought. In Japan's core business, externally commissioned custom development is the most common procurement route at just under 40 percent, while in Germany in-house development, external development and standard software each account for around 30 percent (IPA, 2025). Behind this lies a different distribution of staff – around 70 percent of IT specialists sit at vendors – and a subcontracting chain with up to six tiers.
8. Cloud share high, SaaS share lower than it sounds. In 2024, 65 percent of Japanese market volume fell to cloud deployment, of which only around 22 percent to pure SaaS (Yano); in the mid-market the share of classic on-premises packages even rose between 2020 and 2024 from 36.0 to 41.7 percent (Nork). In Germany, 44 percent run their ERP in the cloud (Bitkom, 2025), and in the mid-market on-premises leads at 52 percent.
9. No list prices, but state subsidies instead. In the BOXIL price overview, 15 out of 15 large vendors quoted no public prices; the range collected is 12,000 to 18,000 yen per user and month. At the same time there is a funding landscape with no German counterpart: up to 4.5 million yen from the digitalisation subsidy, up to 25 million yen from the manufacturing subsidy. On maintenance rates the two markets resemble each other: 15 to 22 against 12 to 25 percent.
10. Payroll and payments follow rules of their own. Japanese payroll spreads five contribution types across three assessment logics, works with prefecture-dependent health insurance rates between 9.44 and 10.78 percent and with a resident tax on the previous year's basis that is remitted separately to every municipality of residence. The paper bill of exchange is being phased out by March 2027, and the fairness act of January 2026 requires payment to fall due within at most 60 days.

Sources and methodology

This page was researched in September 2026 with Japanese-language sources – market research from Yano Research, ITR, Deloitte Tohmatsu MIC and Nork Research, official sources from the tax agency, the Digital Agency, METI, the financial regulator and the data protection commission, association and user studies from JUAS, JSUG, IPA and the SME organisation, as well as vendor annual reports – and interpreted from a German perspective. Market sizes differ from one another by more than a factor of two depending on the scoping; we therefore state publisher and reference year for every figure and show ranges. Market shares are available only as installation or panel shares, not as revenue shares; surveys by comparison portals we label as such, and likewise price figures from consulting and trade portals, because most vendors publish no list prices. We refrain from converting into euros because we only have yen-dollar rates and the yen fluctuated strongly. We have deliberately left out everything that could not be substantiated: the total number of Japanese SMEs, Japan's share of the global ERP market, the level of adoption of digital invoicing via Peppol, the rate of payroll outsourcing, absolute person-month rates, cumulative customer numbers for individual products, a market size for construction ERP, and the contents of the 2026 data protection amendment.
