Japanese inheritance tax, assuming the estate is split in statutory shares. A spouse pays no tax up to ¥160M or the statutory share, whichever is larger. Family size is not in the securities reports, so you can choose it (with no children, parents or siblings also become heirs, so the real figure differs). Business-succession deferrals, lifetime gifts, donations to foundations, debts and other reliefs are not reflected.
