Foreign Tax Credit and Deduction from Inheritance Tax Due in Japan
Introduction
Under the U.S.-Japan estate gift and tax treaty, the Foreign Tax Credit permits tax paid overseas that is similar to or the equivalent of the inheritance tax in Japan, to be deducted from the inheritance tax amount due in Japan.
 
Requirements to fulfill for the Foreign Tax Credit to be applied
In order to be able to qualify for the Foreign Tax Credit, under the Japanese laws, the heir or beneficiary must 1) Receive a foreign asset via inheritance; and 2) Tax that is similar to the inheritance tax in Japan was levied upon the asset in the foreign country in accordance with the law of that foreign country (e.g. estate tax in the United States).

Therefore, if a Japanese heir succeeds to an asset of a deceased that is located outside of Japan, and such asset was subjected to a tax that is similar to the inheritance tax in Japan in the country in which the asset exists, the tax levied upon such asset will be able to qualify for the Foreign Tax Credit.
 
How the Foreign Tax Credit can help avoid Double Taxation
An asset that a deceased Japanese national held in a foreign country outside of Japan can be subjected to the inheritance tax in Japan. Such asset can also be levied a tax that is similar to or the equivalent of an inheritance tax in Japan, in the foreign country that the asset originates from. In such case, some form of tax can be levied upon the same asset in both the foreign country in which the asset originates from, and in Japan.

In order to avoid such double taxation, the tax paid in the foreign country can be deducted from the Japanese inheritance tax due in Japan. Under the Japanese law, the lesser of 1. The tax amount paid overseas; or 2. Amount of Inheritance Tax Due in Japan × (Total Value of Asset(s) in Foreign Country ÷ Total Value of Entire Asset(s) Inherited by Heir) can be deducted from the inheritance tax amount due in Japan.

For example, say an heir inherited an equivalent of 40,000,000 JPY from overseas assets, and inherited 60,000,000 JPY worth of assets in Japan. The amount of inheritance tax to be paid in Japan is 50,000,000 JPY, while the estate tax amount paid in the U.S. was equivalent to 8,000,000 JPY. When the formula in 2. above is applied, 50,000,000 JPY × (40,000,000 JPY ÷ 100,000,000 JPY) = 20,000,000 JPY. Since 20,000,000 JPY is more than 8,000,000 JPY, which was the estate tax amount paid in the U.S., the heir will be able to deduct the lesser of the two amounts (i.e. 8,000,000 JPY) from the 50,000,000 JPY inheritance tax amount that is due to be paid in Japan. In total, the heir will owe 42,000,000 JPY in inheritance tax in Japan.
 
Conclusion
In the event that you pay any taxes overseas that is similar to the inheritance tax in Japan, it is good to know that it is likely to qualify for the Foreign Tax Credit and can be deducted on the inheritance tax return in Japan.
