DIY Car Inspection (Shaken) in Japan

Shaken (車検) is Japan's mandatory vehicle inspection required every 2 years (3 years for new cars). Dealer shaken typically costs ¥100,000-150,000, but user shaken (ユーザー車検) can save you ¥50,000 or more by doing it yourself.

The process involves booking a slot at your local inspection center (軽自動車検査協会 for kei cars, 運輸支局 for regular cars), paying mandatory fees (weight tax, jibaiseki insurance, inspection fee), and driving through the inspection line.

Common fail points include headlight alignment (光軸), worn wiper blades, tire tread depth, and brake pad thickness. Visit a "tester-ya" (テスター屋) near the inspection center before your test - they'll check and adjust these items for ¥1,000-3,000.

Pro tip: If you fail, you can fix the problem and return for free re-inspection the same day. From April 2025, you can do shaken up to 2 months before expiry without affecting your next expiry date.

Frequently Asked Questions

Shaken (sha-ken, or vehicle safety inspection) is Japan's mandatory roadworthiness certification required for all vehicles to drive legally on public roads. New passenger cars must pass their first shaken inspection after 3 years, then every 2 years thereafter. Kei trucks and commercial vehicles have different intervals. Driving without valid shaken is illegal and can result in a fine of up to ¥500,000 plus license suspension, so tracking your shaken expiry date is essential for every vehicle owner in Japan.
Doing user shaken (yuuza shaken) yourself at a government inspection center costs ¥40,000 to ¥60,000 covering mandatory taxes, insurance, and inspection fees only — you perform all safety checks personally. Taking your car to a dealer or specialty shop for shaken costs ¥100,000 to ¥200,000 or more once labor, replacement parts, and handling fees are added. Most mechanically capable vehicle owners in Japan can save ¥50,000 to ¥150,000 per shaken cycle by doing it themselves.
Japan's shaken inspection covers all major vehicle safety systems: brake function and lining thickness, all exterior and interior lights including indicators and reflectors, exhaust emissions against regulated limits, tire tread depth and condition, suspension and shock absorbers, windshield wipers, horn function, steering play, exhaust system integrity, and overall body condition for rust or structural damage. Lights and exhaust emissions are the most common shaken failure points, so check these before your appointment.
Your shaken expiration date is shown in two places: on a small sticker affixed to the lower center of your windshield displaying the year and month of expiry, and on your shaken certificate (sha-ken sho) kept in the vehicle's glove compartment. You can bring your car in for shaken up to 1 month before the expiration date without losing your renewal cycle date, meaning your new shaken will still be calculated from the original expiry month rather than the actual inspection date.
If your vehicle fails shaken, the inspection station issues a failure report (fuugoukaku tsuchisho) listing the specific items that did not meet standards. You have two options: repair the identified problems and return for a free re-inspection within 2 weeks at the same station (within the same inspection cycle), or take the car to a garage for repairs and return for a reinspection at any inspection station within 3 months. Driving an unregistered or shaken-expired vehicle on public roads remains illegal during the repair period.
