The Role of Shaken (車検) in Maintenance Costs
One of the largest mandatory expenses is shaken, Japan’s vehicle inspection system. Every car must pass this inspection once it reaches three years old, and then every two years after that. Shaken includes technical inspection, weight tax, and mandatory insurance.
When broken down annually, shaken costs between ¥30,000 for kei cars and ¥70,000 for luxury vehicles. This expense is non-negotiable, and failing to renew shaken means you cannot legally drive your car.
Insurance: Mandatory and Voluntary Coverage
In Japan, every driver must have Compulsory Automobile Liability Insurance (CALI). However, most people also buy voluntary insurance for better protection.
On average, kei cars and compact vehicles cost about ¥60,000–¥70,000 per year in insurance, while larger sedans, SUVs, and luxury cars can reach ¥150,000 or more. These numbers vary depending on the driver’s age, history, and the insurance company, but they remain a consistent part of annual expenses.
Routine Maintenance: Oil, Tires, and Repairs
Beyond official fees, every car needs basic maintenance. Oil changes, tire replacements, and unexpected repairs depend on how much you drive each year.
For example, if you drive 10,000 km annually, a kei car might add only ¥100,000 in maintenance, while a luxury SUV could easily exceed ¥200,000. The more kilometers you drive, the higher these costs become, especially for vehicles with larger engines and more expensive parts.
Why Costs Differ Between Car Types
Car type matters a lot in Japan. Kei cars (660cc or less) are the cheapest to maintain, thanks to lower shaken fees, smaller tires, and reduced insurance premiums. Compact cars and sedans are more expensive, but still reasonable for families. SUVs, minivans, and luxury cars come with much higher costs because they consume more fuel, use larger tires, and are taxed at higher rates.
Choosing the right car type can make the difference between ¥150,000 per year and over ¥400,000 per year in total maintenance costs.
