Inheritance tax (estimate)

Estate ¥896M = listed shares in own name ¥598M + other assets (est.) ¥298M

Total inheritance tax paid: ¥153M (17.1% of the estate).

HeirInheritsTaxAfter tax
Spouse¥448M¥0¥448M
Each child¥224M¥76.7M¥147M

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.

Estimates from annual securities reports (EDINET). The English name is romanized automatically and may differ from the spelling the person uses. Methodology · Corrections and removal requests: contact
