If you (a foreigner working in Japan) have earned a salary, you are probably subject to tax (income tax) in Japan.
If you have a dependent spouse or child, your income tax will be reduced. This is called the “dependent, etc. exemption.” It is irrelevant whether they live in a foreign country or Japan. Even if they live in a foreign country, they can receive the exemption for dependents by submitting certain documents.
How much tax will be reduced by the exemption for dependents?
Suppose your tax rate is 10%, and you have a spouse and one 19-year-old child
Your income tax will be reduced by (380,000+63,000)*10%=101,000 per year.
Amount of exemption for dependents
Children between 16 and 19 years old: 380,000 yen
Children between the ages of 19 and 23: 630,000 yen
Parents over 70 years old: 480,000 yen to 580,000 yen
Spouse: 380,000 yen
If you have not received this deduction in the past, you can receive a refund for up to 5 years retroactively.
101,000*5 years = 505,000 yen
The above is a significantly simplified explanation of the requirements. In reality, there are various other detailed requirements, and you need to submit quite a lot of documents.
