Taxes and fees in Japan are directly deducted from wages. Since you have two jobs, you have to pay two taxes for two salaries.
The part directly deducted from the salary of part-time workers is called income tax, which is the need for studying in Japan paid by the employer company or shop instead of me. The amount of income tax varies according to wages. Generally, 1 0% of the total amount will be deducted from the salary of translators (those who live in Japan for1year or more).
