Japan has only one estate tax treaty, signed with the United States in 1955. The treaty is designed to prevent double taxation for inheritances that involve both US and Japanese inheritance tax law.
When Japanese estates involve jurisdictions other than America, the heirs should carefully discuss the implications for double taxation with an attorney and accountant. With careful planning there may be a way to avoid double taxation.
