Spending, real estate, donations and savings from earlier years are not reflected.

"Partial" years carry forward the previous year's value for companies that have not yet filed that year's annual report (such as December year-end companies). Pay and dividends cover only companies that have filed.

Net worth for each year is listed shares plus the other assets (est.) accumulated up to that year. Grouped by the calendar year of each company's fiscal year-end. Years in which the person was not among the top 10 shareholders of a company exclude that company.

Inheritance tax (estimate)

Estate ¥335M = listed shares in own name ¥301M + other assets (est.) ¥33.8M

Total inheritance tax paid: ¥34.7M (10.4% of the estate).

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
