Cost (annual)	Type	Amount

Cars over 13 years old pay a surcharge on 自動車税 and 重量税 (roughly +15%). This calculator uses standard rates and does not add it — so for an older car (a common, cheap first car), the real tax will run a little higher than shown.

Paying too much for 任意保険? Premiums vary a lot by age and 等級 — comparing quotes can cut it. Note: the quote form is in Japanese.
