How to Buy a Car in Japan

Buying a Car in Japan: What You Really Need to Know

Buying a car in Japan is a completely accessible process, but it involves a number of administrative steps that many foreigners don't know about before they start. And believe me, if you don't have at least an intermediate level of Japanese, it's going to get very complicated quickly.

Why Buy a Car in Japan?

In big cities like Tokyo or Osaka, public transportation is so efficient that a car is often unnecessary, even costly to maintain. But if you live in a medium-sized city, in the suburbs, or in a rural area, a car quickly becomes essential. Used car prices are also very affordable in Japan, sometimes even surprising for a European.

The Inkan and Inkan Shomeisho: The Foundation of Everything

Before even talking about a car, you need to understand a fundamental Japanese reality: the hanko (判子) system, in other words, your personal seal. In Japan, a handwritten signature has no legal value in most important transactions. What matters is your inkan, a stamp engraved with your name that you register at the city hall.

To buy a car, you will need an inkan shomeisho (印鑑証明書), which is an official certificate proving that your seal is registered with your municipality. This document is requested at the city hall of your place of residence, and it generally needs to be renewed regularly as it has a limited validity of three months. Without this document, it's impossible to finalize a real estate or automobile purchase in Japan. It's non-negotiable.

If you haven't registered your inkan yet, that's the first step. Go to your city hall with your residence card (在留カード), your seal, and the corresponding forms. Everything is, of course, in Japanese.

The Shakoshoumei: A Foreigner's Nightmare

This is where many people get stuck, and yet it's mandatory. The shako shomei (車庫証明), literally the "garage certificate," is a document you must obtain from the local police station before you can register your vehicle. This certificate proves that you have a parking space within two kilometers of your home.

To obtain it, you need to provide a map of the parking space, a document proving you have the right to use that space (lease, building owner's attestation, etc.), as well as your exact address. If you are renting and your parking is included in your lease, the landlord will need to provide you with a specific attestation. Everything is in Japanese, the forms are in Japanese, the police station staff speak Japanese.

This document usually takes between three and seven business days to be issued, so plan ahead.

The Shaken: Maintaining Your Car in Japan

The shaken (車検) is the Japanese vehicle inspection, but taken to a level far beyond what we know in Europe. It is mandatory every two years for most vehicles, and it includes a very comprehensive technical inspection, mandatory insurance and tax fees, as well as any necessary repairs to make the vehicle compliant. The cost can easily exceed 100,000 yen depending on the condition of the vehicle. When you buy a used car, always check the date of the next shaken, as it's a determining factor in the real price you pay.

Platforms for Buying

The two main references for buying used cars in Japan are Goo-net (グーネット) and Car Sensor (カーセンサー). You'll find thousands of listings there with all the information on mileage, shaken, vehicle history, etc. There are also auctions through dealers, but those are for more experienced profiles.

And What About Japanese in All This?

Let's be direct: buying a car in Japan without speaking Japanese is extremely difficult. The administrative forms, the exchanges with the police station for the shako shomei, the city hall for the inkan shomeisho, the dealer for the purchase contract, the car insurance... everything is done in Japanese. There really is no alternative, and agencies that offer English support are often significantly more expensive.

This is a reality found in many procedures in Japan: the language is not a plus, it's a necessity.
