Motor-vehicle inspection (Japan)

The registration and inspection process may be performed by the owner of the vehicle, though it is most commonly contracted to a professional mechanic or a dealership.

A typical third-party shaken for a small or normal sized passenger vehicle costs between ¥100,000 (US$806) and ¥200,000 (US$1,612).

[5] Vehicles with an engine displacement of 250 cc (15 cu in) or less are exempt and therefore not required to undergo an inspection.

[citation needed] The process of the shaken involves these steps: Should a car not meet any of the tests, it will have to be repaired and retested before passing.

[citation needed] All headlamps must be an approved type, designed for left-hand traffic, emit white or yellow light, and be aimed correctly.

Incorrect headlight colour, depending on the person's knowledge during the inspection, will result in a fail.

[dubious – discuss] Cars older than 10 years may emit up to 4.5% carbon monoxide and up to 1200ppm unburned hydrocarbons.

[citation needed] All oxygen sensors must be in working order along with any oil catch tanks.
