The Short Answer

Special benefits are gifts or advances given by a deceased person to an heir during their lifetime, and they reduce that heir’s statutory inheritance share under Japanese civil law.

What the Law Says

Japanese civil law treats certain lifetime transfers from a decedent to an heir as 'special benefits' that must be accounted for when calculating inheritance shares.

Under Article 903 of the Japanese Civil Code, if an heir received property from the deceased as a gift or advance (e.g., for marriage, adoption, or livelihood support), that amount is added back to the estate for calculation purposes — then subtracted from the heir’s final inheritance share.

This ensures fairness among heirs: the heir who received early support does not receive a double benefit. The law applies only to transfers made with the intent to provide for the heir’s future, not ordinary gifts or loans without such intent.

The value of the special benefit is calculated at the time it was given, not at the time of inheritance. If the property has appreciated or depreciated, the original value is used.

Statutory Text

If an heir has received a gift or advance from the decedent for marriage, adoption or livelihood, the value of such gift or advance shall be added to the value of the estate for the purpose of calculating the statutory share, and shall be deducted from the share of the heir who received it.

What to Do

1

Identify all lifetime transfers from the deceased to each heir (e.g., wedding money, tuition payments, home purchase assistance).

2

Determine whether each transfer qualifies as a 'special benefit' under Civil Code Art. 903 — i.e., made for marriage, adoption, or livelihood support.

3

Calculate the value of each qualifying benefit at the time it was given.

4

Add those values to the gross estate, then compute each heir’s statutory share based on the adjusted total.

5

Subtract the special benefit amount from the qualifying heir’s final share before distribution.
