What this solves
Rental cars in Japan are surprisingly affordable (¥4,500-9,000/day for compact) but the hidden costs hit hard: expressway tolls (Tokyo–Kyoto one-way ¥11,000), ETC card rental (¥330/day + ¥5 commission per use), parking (¥300-800/hour in cities, ¥1,500-3,000/day at hotels), insurance excess waiver (¥1,500/day). This tool rolls all in.

How to read results
- Expressway toll: about ¥25-30/km on most urban expressways, ¥15-25/km on rural ones. ETC discount is ~10% on weekdays, 20% on weekends/holidays (Hokkaido, Tohoku, San'in) and on the ETC "Mileage" weekend point system.
- Tokyo Y-class kei car: smallest (660 cc), cheapest, parks in narrow spots. Most companies require kei cars for Hakone mountain roads due to width.
- Narrow streets: 50% of Japanese urban roads are under 4 m wide with no sidewalks — passing a car requires one to back up. Rental insurance excess (CDW) typically ¥50,000-100,000; full-fee suspension ¥1,500-3,650/day.
- International Driving Permit: required. Japan honors the 1949 Geneva IDB Compact (most countries) — must be issued BEFORE arriving in Japan. Taiwan, Germany, France, Switzerland, Belgium, Monaco, Estonia are exceptions (need official translation).
Limitations
2026 reference prices. Expressway tolls change at midnight +0 yen on all cars April 2026 (planned at time of writing — verify). Rental rates vary by season (Hokkaido winter 2x). Real parking in Tokyo can hit ¥5,000/night near Shinjuku Station.
FAQ
Do I really need an IDP?
Yes. Without a valid 1949 IDB IDP you cannot legally drive; the rental counter will refuse you. Some countries (Taiwan, Vietnam, Thailand) need an official JAF translation instead. Carrying passport is required at all times.
Should I rent in Tokyo?
Probably not — traffic is heavy, parking is expensive, public transit is excellent. Rent in Kansai (Osaka/Kyoto/Nara) or Hokkaido (Sapporo) where car makes sense.
Why is my IDP valid in Switzerland but not in France?
Both work — France and Switzerland both honor the 1949 IDB IDP. Some countries don't sign the 1949 treaty; for them, Japan requires an official translation via JAF (¥4,000).
