Checked against the official page on 2026-10-20. Part of Oak’s directory of Japanese business grants.
Before you apply
- The money is not up front. You pay for the whole project yourself. The grant reimburses a share of it (often half to two-thirds) after a completion report has been checked, typically 6 to 18 months after applying.
- Do not spend before approval. Costs ordered, contracted or paid before the official grant decision (交付決定) are usually not eligible.
- Competitive and strict. Business plans are scored against other applicants and many are rejected. Eligibility rules on company size, ownership and tax compliance are applied to the letter.
- Obligations continue after payment. Reports for up to five years, inspections, and targets in your plan. Missing them can mean repaying part or all of the grant.
