Calculated, not filed. Null where the holder's filing gives no usable denominator, never zero. holder_equity_basis says which accounting figure the denominator is, and a parent_only basis is not comparable with a consolidated one. A position CAN legitimately exceed 100% of equity — a holder whose book equity is smaller than one long-held stake is a real and commercially interesting case, not an error — so no ceiling is imposed. Extreme values are worth checking against the filing: where the position's own two filed numbers are mutually impossible the row is marked `implausible`, but that test catches only scale errors visible per share, so it does not catch every bad figure. The book value and share count are returned alongside so the reader can check.","action_calc":"keyword match over the filing's own stated purpose and table footnotes: 株式分割、株式併合、株式交換、株式移転、会社分割、合併、持株会社、商号変更、公開買付、上場廃止","ratio_calc":"current shares ÷ prior shares where that ratio is an exact whole number (or its exact reciprocal) — the signature of a split or a consolidation rather than a trade","history":[{"year":"2022","period_end":"2022-03-31","named_holdings":23,"book_value_yen":4694000000},{"year":"2023","period_end":"2023-03-31","named_holdings":21,"book_value_yen":4525000000},{"year":"2024","period_end":"2024-03-31","named_holdings":21,"book_value_yen":5946000000},{"year":"2025","period_end":"2025-03-31","named_holdings":21,"book_value_yen":6100000000},{"year":"2026","period_end":"2026-03-31","named_holdings":21,"book_value_yen":7941000000}],"history_note":"One point per annual report filed.
