There are two types of Car insurance in Japan.
They are the government's compulsory insurance and voluntary insurance.
The government's compulsory insurance alone does not cover money in the event of an accident.
Therefore, most people purchase voluntary insurance.
Since I apply for insurance online, my premiums are lower than other people's.
But it still costs about $153 (20,000 yen) per year.
It is not cheap, but it is important to be prepared for any eventuality.
