The archive reaches back only as far as the capture does — EDINET's own list API reaches about five years — so an accumulation that began earlier is visible from its first captured report onward, not from its start.","event_note":"Each row is one report as filed on its own trigger date, not a running position. A holding group that drops below 5% files once more and then stops filing, so the absence of recent reports is not evidence of a position.","tape_note":"The tape is ordered by the date each report was FILED, which is when the market could read it. The trigger date beside it is the filing's own 提出義務発生日 and is shown as filed — a change report often restates the date the holder first crossed 5%, and a handful of filers mistype it outright, so ordering on it would put a typo at the top of the page.","group_note":"Positions are per filing GROUP (a filer plus its joint holders). The group ratio is the filing's own, not our sum of the members: the form deducts claims between joint holders, and a member that has left the group is still described in the report with last-report figures only.","proposal_note":"important_proposal is the filed answer to 重要提案行為等 — the acts under Article 27-26 that separate a campaign from a passive stake — read as true when the holder states it will, may or has made such proposals and false when it states none. The general form asks it on initial, change and amendment reports alike; the special-reporting form used by institutions that undertake to make no proposals carries no such field, and proposal_asked is false there. An answer that does not address the question (a lock-up clause typed into the box, say) is null with proposal_stance 'unclear'. A null answer never means 'no'.","ratio_note":"ratio_pct is the statutory 株券等保有割合. Its denominator is 発行済株式等総数 plus the holder's own potential shares and its numerator excludes underwritten shares, so it does not equal shares_held / shares_outstanding; both are published as filed.","names_note":"English company names are as filed: each company's own annual report states its English name on the cover page. For a company that files no annual report, EDINET's filer registry is used instead. The as-filed Japanese name is always returned alongside.","calc":{"ratio_change_pp":"ratio_pct − prior_ratio_pct, both as filed (percentage points)","is_current":"the group's latest report shows ratio_pct >= 5","activist_filings":"filings where any holder states an act under 重要提案行為等","filed_date":"the date EDINET received the document, from its own submission record — not the date printed on the cover page, which the filer types and occasionally gets wrong (cover_date keeps that one)","days_to_file":"filed_date − requirement_date, in days. NOT a lateness measure: a change report often restates the date the holder first crossed 5%, years earlier","proposal_stance":"the filed 重要提案行為 answer read as will_or_may (states it will, may or has made important proposals), none_planned (states none, in any wording) or unclear (text that does not answer the question, such as a lock-up clause typed into the box); a filing's stance is will_or_may if any holder's is","purpose_mentions_proposal":"the 保有目的 (purpose) reserves important proposals in a clause that does not deny a plan. Large asset managers write this into nearly every report as boilerplate, so it is not a campaign signal on its own","date_quality":"ok, or after_filing (trigger date later than the date EDINET received the report), before_5pct_rule (earlier than 1 December 1990, when the rule began) or missing","unique_proposal_docs":"distinct reports with important_proposal true; proposal_reports counts holder lines, so a joint filing counts once per co-filer there"},"provenance":{"trust":"official","note":"Figures exactly as filed in each company's 有価証券報告書 (annual securities report), EDINET.
