8 Common Mistakes When Applying for Subsidies in Japan (and How to Avoid Them)

Many businesses build a good project and still lose the subsidy over details. These are the most common mistakes, based on the official rules of the デジタル化・AI導入補助金2026 and the 持続化補助金.

1. Signing or paying before the 交付決定

Mistake number one. In the IT program, any contract, order or payment before the grant decision, even partial, means you lose the subsidy. Getting quotes is fine; closing the deal is not.

2. Leaving GビズIDプライム to the last minute

By mail it takes about 2 weeks. No account, no application.

3. Forgetting SECURITY ACTION

Mandatory for the IT program. The ID is issued quickly now, but it must be done first.

4. Applying for a website alone under the 持続化補助金

Website costs can be at most 1/4 of the grant and cannot be the only expense.

5. Missing the 商工会 deadline

For the 持続化補助金, the 商工会/商工会議所 document (様式4) has a deadline before applications close.

6. Choosing a tool for the subsidy, not the need

A system nobody uses is still a loss, even at half price.

7. Not keeping records

Quote, order, delivery, invoice and payment: without the full paper trail, the cost is rejected.

8. Forgetting post-grant duties

Programs require reports after implementation. Missing them can mean repayment.

Note: rules, amounts and deadlines change every round. Always check the latest official call (公募要領) before applying.
