According to the Ministry of Foreign Affairs:
The fees are about 3,000 yen for a single-entry visa, 6,000 yen for a double-entry or multiple-entry visa, and 700 yen for a transit visa. Fees are collected in the currency of the country (region) in which the Embassy / Consulate General is located.
Depending on the purpose of your visit and your nationality, fees may not be required or may be a different amount.
But there is zero information about the price on the local website.
