Why Goukaku Drive
Free forever
No subscription and no sign-up required. Every mock and every question is free — and it stays that way.
Only Gaimen Kirikae
We do one thing: the foreign-license conversion written test. No other licence types diluting the question bank.
Multiple languages, growing
Take the test in your language. We launch in more than one and keep adding — the language picker is the proof.
Transparent & community-improved
Every question can be reported. Errata drive AI-assisted fixes, so the bank gets sharper the more it's used.
