Frequently asked questions

Gaimen Go is for people preparing for the Japanese foreign-licence conversion knowledge confirmation, often called Gaimen Kirikae.

No. Gaimen Go is an independent practice resource. It is not operated by, affiliated with, or endorsed by a police or government authority.

No. Practice can help you build familiarity with road rules and the question format, but your result depends on the current requirements and your own preparation.

The free demo is a repeatable 25-question, 15-minute practice attempt from a fixed public sample. You can use it without an account and review every answer after submission.

Full practice exams contain 50 varied true/false questions. The Fuchu-style option uses the app's 30-minute practice timer; the general option uses the same balanced question format without an official-time claim.

Correct answers and explanations appear only after you submit or the attempt expires. They are not shown while you are answering.

Yes. Answers and flags save as you go. You can resume an active account-owned full exam without using another credit, provided its time window has not ended.

Gaimen Go currently supports English and Japanese learner experiences. Each attempt stays in the language selected when it was created.

Tokyo publishes a 50-question true/false knowledge-confirmation format and a 45/50 pass mark. Gaimen Go uses those published facts for its full-exam practice structure, but it is not an official test.

Tokyo does not publish a Fuchu time limit. The app's 30-minute setting is a realistic practice choice based on corroborated recent test-taker reports, not an official claim.

After the 30-minute practice timer ends, Gaimen Go gives one final minute to make changes or submit. This is an app convenience and is not part of the official test.

One credit creates one new 50-question full practice exam. Resuming, saving answers, submitting, and reviewing the same attempt do not use another credit.

No. Credits are non-expiring and remain attached to the purchasing account.

Not yet. Checkout is still being prepared. The Pricing page shows the planned credit packs, but it does not collect payment details or create purchases.

Your foreign licence generally needs to remain valid, and you generally need to prove at least three months in the issuing country after obtaining it. The exact review depends on your own circumstances.

That depends on the country or region that issued your licence and the current prefectural procedure. Check the latest instructions with your local driving licence center before applying.

Use the official Tokyo Metropolitan Police guidance if applying in Tokyo, and JAF guidance for general conversion information. Documents, appointments, fees, exemptions, and locations can vary.

Use the feedback form or the Report this question action on completed results. Reports about unclear, inaccurate, outdated, duplicated, irrelevant, or technically broken content help improve the question bank.
