Using the Monozukuri Subsidy for AI
Full name: "Monozukuri, Shogyo, Service Seisansei Kojo Sokushin Hojo-kin" (Manufacturing, Commerce, and Service Productivity Improvement Subsidy). Well-suited for innovative product/service development incorporating AI, and large equipment + AI investments.
| Cap (indicative) | Varies by category and size. 51+ employees: ¥25M (¥35M with wage-increase special measure), Global category: ¥30M, up to ¥40M class (including wage-increase special measure) * The cap changes by category, size and wage-increase status. These are indicative — always check the official call guidelines. |
|---|---|
| Rate (indicative) | Standard: 1/2 Micro-businesses: 2/3 |
| Main categories (FY2026) | High-value-added products/services (renamed "Innovative New Products/Services" from FY2026), Global category, etc. |
| Key eligibility criteria | At least 1 salaried employee / average annual growth in value-added ≥3% over 3–5 years post-project, etc. |
| AI use cases | Innovative product/service development incorporating AI, equipment + AI productivity investments. Better suited than IT subsidy for larger, equipment-focused investments. |

Application flow (5 steps)
Using a subsidy for AI adoption roughly follows these 5 steps.
| STEP 1 | Assess current state — identify which tasks AI can help with and estimate the impact. Your AI assessment results can form the foundation of your business plan. |
|---|---|
| STEP 2 | Select eligible tools / projects — for IT subsidy: confirm the tool is registered; for Monozukuri: confirm your project meets the innovation and value-added requirements. |
| STEP 3 | Write the business plan — demonstrate outcomes with numbers, align with policy goals (productivity, wages, DX). Start preparing documents 2–3 months before the deadline. |
| STEP 4 | Apply by the deadline — confirm the latest deadline on the official site and submit on time. |
| STEP 5 | Contract / adopt after approval → results report — as a rule, ordering before approval makes costs ineligible. Receive the subsidy after submitting a results report. |
3 tips to improve approval chances
Plans that quantify outcomes — "current hours → estimated reduction after AI," "projected increase in value-added" — tend to score better. Clearly label estimates as indicative model cases and provide the reasoning behind them.
Explicitly connecting your investment to national goals — productivity improvement, wage growth, DX — is important. Frame what AI will change and how using the program's own keywords.
Vague language like "using AI" is not enough. Describe the specific task, the approach and the expected outcome — e.g., "automate __ invoice entries per month, targeting __ hours saved." Use your free AI assessment results as the basis for your business plan.

FAQ
Can AI tools be covered by the IT Introduction Subsidy?
From 2026 the program was renamed the Digitalization / AI-Adoption Subsidy 2026, and AI-capable tools are now explicitly eligible. However, only tools registered and applied for as AI-function tools by a registered IT support provider qualify — generative AI tools do not qualify automatically.
Which subsidy should I use — IT Introduction or Monozukuri?
Software- and SaaS-centered adoption (AI-OCR, chatbots, etc.) tends to fit the IT Introduction Subsidy; large investments in equipment plus AI, or developing innovative AI-driven products and services, tend to fit the Monozukuri Subsidy. The right choice depends on your specific investment.
What are the subsidy rates and caps?
The IT Introduction Subsidy covers up to ¥4.5M at up to 1/2 (up to 4/5 for the invoice category, micro-businesses). The Monozukuri Subsidy can reach up to the ¥40M class depending on category and size, at 1/2 (2/3 for micro-businesses) — these are indicative figures. Always check the latest official call guidelines for current requirements.
Is approval guaranteed if I apply?
No. Subsidies are awarded through a competitive review, and approval is not guaranteed. Business plans that align with policy goals and demonstrate outcomes with concrete numbers tend to have higher approval rates.
When can I apply? What are the deadlines?
Each program runs multiple rounds with separate deadlines that may change. At the time this article was written, recent rounds may already be closed. Always check the latest round and deadline on each program's official website.
