"We want to adopt AI, but cost is the barrier" — a common worry from SME owners in Chiba. In fact, as of 2026, national subsidies alone can cover 1/2–4/5 of AI adoption cost, and up to ¥100M for large investment including equipment. This article organizes the subsidies and support programs SMEs in Chiba can use, plus the application flow and pitfalls.
① Digitalization / AI-Adoption Subsidy 2026 (formerly the IT Introduction Subsidy)
Japan's flagship national subsidy for SME IT/AI adoption. From 2026 the "IT Introduction Subsidy" was renamed the "Digitalization / AI-Adoption Subsidy," foregrounding support for AI tools and AI-equipped SaaS. Costs for automation tools, AI chatbots, analytics tools and generative-AI services can be eligible.
| Amount | Up to ¥4.5M (by application category) |
|---|---|
| Subsidy rate | 1/2–4/5 (preferential for micro-businesses) |

② SME Labor-Saving Investment Subsidy
A national subsidy supporting labor-saving investment such as AI, IoT and robots as a labor-shortage measure. There's a "catalog-order type" (choose from pre-registered products) and a "general type" (build a custom system/equipment for your operations).

③ Chiba Prefecture / Chiba City support
Chiba: SME Digital Technology Utilization Support
A "digital support coordinator" at the Chiba Prefecture Industrial Promotion Center provides free hands-on support from organizing challenges to deciding requirements for digital tools and matching with IT vendors — a great place to consult at the "don't know where to start" stage. Expert dispatch (with subsidies for fees/travel) is also available.
Chiba: Advanced Digital Technology Demonstration Project Subsidy
A prefectural subsidy supporting demonstration projects for new products/services using digital tech. Firms tackling new AI-based service development should watch the call timing.
Chiba City support
Chiba City, via its industry-promotion foundation, also offers expert dispatch and help with national subsidy applications. City-specific measures change yearly, so check the official Chiba City sites for the latest.
The flow of AI adoption with subsidies
Using subsidies roughly follows these 5 steps.
| STEP 1 | Assess current state — which work AI helps with, and how much it can save |
|---|---|
| STEP 2 | Select tools/measures — choose eligible tools/vendors |
| STEP 3 | Apply — prepare the business plan per the guidelines and apply by the deadline |
| STEP 4 | Approval → adoption — contract, adopt and pay after approval |
| STEP 5 | Results report — report outcomes and receive the subsidy |
Start by spotting "where AI helps"
Subsidies are a means, not the goal. Knowing first "which of your tasks gains most from AI" keeps your choice of subsidy and tools focused and makes your business plan more convincing.
MRI Inc. (Chiba City) offers a free AI assessment scoring your AI potential in 12 questions / ~3 minutes, plus a free consultation oriented toward using subsidies. Based on the result, we support choosing the right subsidy/tools, PoC and full adoption — one-stop.
