## What is DriveNihon?

Converting your foreign driver's license to a Japanese one (外免切替)?

Since 1 October 2025 the knowledge check (知識確認) uses a new format: 50 true/false questions in 30 minutes, and you need 45 correct. DriveNihon lets you practice exactly that format in English, with the original Japanese right underneath.

ANSWERS YOU CAN VERIFY
• Every question cites its basis: an article of the Road Traffic Act or a section of the Rules of the Road (交通の教則, 2026 edition)
• A report button on every question and a public correction log in the app
• Kept up to date with new rules, such as the 30 km/h limit on roads without a center line from September 2026

PRACTICE LIKE THE REAL TEST
• 50-question mock exams with a 30-minute timer, scored against the 45/50 pass mark
• Every exam covers all 12 topics, with results by topic
• Practice 12 topics with instant answers and explanations
• Review your mistakes and flag questions to revisit during an exam

ENGLISH AND JAPANESE SIDE BY SIDE
• Interface in English, Vietnamese and Japanese
• Show or hide the original Japanese to learn the wording used in the test

GET READY FOR THE DRIVING CHECK (技能確認)

• Based on National Police Agency guidelines

FREE
• A fixed 50-question sample exam (retake anytime), 50 practice questions, 5 trap questions, road sign library, 外免切替 procedure guide
