Shaken (??), a contraction of Jid?sha Kensa T?rokuseido (?????????, "automobile inspection registration system"), is the name of the vehicle inspection program in Japan for motor vehicles over 250 cc in engine displacement.

Reason for existence
The inspection system is in place to ensure that vehicles on Japanese roads are properly maintained and are safe to be on the road. Another reason is to determine if a vehicle has been illegally modified. Illegally modified vehicles and vehicles deemed unsafe will have a red sticker with the following: fuseikaizousha (?????) (Illegal Vehicle) in yellow and the date the vehicle was declared not fit to be on the street.

Registration and cost
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. The cost for the shaken is broken up as follows:
- Paperwork fee
- Inspection fee
- Compulsory vehicle insurance
- Vehicle weight tax
For a new registration there are also additional fees for registration and number plates.
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). However, these prices often include large service fees so the cost of a self-performed "user" shaken is much lower, although exact prices are dependent on the size, weight and age of the vehicle.
Renewal periods
An initial inspection occurs at the vehicle's first registration and renewal inspections must then take place at prescribed intervals thereafter.
Vehicles with engine displacement under 250 cc (15 cu in) are exempt and therefore not required to undergo an inspection.
Testing process
The process of the shaken involves these steps:
- An exterior inspection to ensure the vehicle meets Japanese exterior regulations and does not have illegal exterior modifications such as extreme body kits that increase the exterior dimensions.
- A wheel alignment inspection to ensure the vehicle has its wheels in-line and can turn correctly.
- A speedometer inspection to ensure the vehicle's speedometer is accurate.
- A headlamp inspection to ensure that the vehicle's headlights are correctly placed and aligned.
- A brake inspection to ensure the brakes work correctly.
- An exhaust gas/muffler inspection which includes testing carbon monoxide and hydrocarbon emissions along with exhaust noise levels.
- An undercarriage inspection which includes looking at suspension parts.
Should a car not meet any of the tests it will have to be repaired and retested before passing.
Requirements
Exterior
- Tailpipes: Tailpipes are not allowed to protrude past the car's body however tailpipes that are built into the side of the vehicle are allowed.
- Body kits/Aero parts: Aerodynamic mirrors, windage trays under the tail section of the car and body kits using front bumper scoops are allowed. However all aerodynamic parts must fit and be molded correctly so they are flush with the car's body.
- Fenders and Overfenders: All fenders and overfenders (including widebody style-kits) must not inhibit the turning of the car's wheels (which must be able to turn 30 degrees inward and 50 degrees outward).
- Spoilers: All spoilers (aftermarket or OEM) must not be wider than the car's rear and must be bolted to the car's trunk.
- Lamps and reflectors: Front, side, and rear turn signals; brake lights, front and rear position lights, hazard warning lights, rear reflectors, low and high beam headlamps are all required. Sidemarker reflectors and lights and fog and driving lamps are permitted. All devices must function correctly and emit or reflect the required colours of light.
- Windows: No tint can be present on driver and passenger side windows however commercial UV window blocker is allowed. Lexan windows are not allowed unless they are approved via a case by case basis. Stickers/banners on the front windshield and rear glass are not allowed. etching on the windows, with the exception of VIN information, is not allowed.
Speedometer
The speedometer of the car is tested by driving up on to a dynamometer. The vehicle will be accelerated to 40 km/h twice and the vehicle's speedometer reading will be recorded; should the reading be different, it will not pass.
Headlamps
All headlamps must be an approved type, designed for left-hand traffic, emit white or yellow light, and be aimed correctly.
Exhaust and Emissions
Cars under 10 years old may emit not more than 1% carbon monoxide, and not more than 300ppm unburned hydrocarbons. Cars older than 10 years may emit up to 4.5% carbon monoxide and up to 1200ppm unburned hydrocarbons. This emission standard is laid out in the Japanese Emission Standard legislation. High flow catalytic converters are allowed. All oxygen sensors must be in working order along with any oil catch tanks. Exhaust noise is tested at a 45-degree angle, 50 centimetres (20 inches) from the tailpipe outlet. Vehicles up to 10 years old may emit not more than 96 decibels; older vehicles are allowed 103 dB.
Suspension
No bushings may be broken or in bad condition. All control arms must be in working order. There can be no rust/corrosion on springs, struts or other suspension components. If the car has 4 wheel steering it must be working. The vehicle must also meet minimum height requirements which will be checked by referencing the lowest part of the vehicle (not including the suspension components). For vehicles with 200-249 cm wheelbase they must be 8 cm off the ground and vehicles with 250-299 cm wheelbase they must be 9 cm off the ground. For all other vehicles for every 50 cm over 299 cm in wheelbase add .5 cm to the minimum height and for vehicles under 200 cm in wheelbase subtract .5 cm to the minimum height.
Interior
General interior equipment must be still intact (i.e.: dash). Roll cages (must have padding around bars) and carpet removal is allowed. Bucket seats must measure 420 mm from left to right bank but can not be over 450 mm from left exterior side to right exterior side (total width of seat). Aftermarket seats made of fiber-reinforced plastic are not allowed. Any holes or rips in seats must either be taped up or repaired.
Older vehicles
As vehicles get older, maintaining them to the required standards can become expensive. Most Japanese do not get involved in mechanical repairs, and as a result, mechanics can charge high prices. Vehicles which cannot pass inspection are not permitted on public roads. Unwanted vehicles must be exported or destroyed and recycled. Many Japanese used vehicles are exported once it is no longer cost-effective to keep them in service in Japan.
