The median gap between filing days is 42 days. The latest filing is an ad hoc filing dated 2026-07-01, 128 days before the record date of 2026-11-06.

Its location is not on the record. Auditor changes are not on the record, as this market's register does not yet carry lifecycle type maps.\n\n## Events and halts\n\nListing, delisting, name change, domicile change and segment move are not on the record, as this register has no lifecycle type map yet. The halt flag shows the issuer as listed, not halted.\n\n## Orderability\n\nFor the client category Qualified Institutional Investors, the outcome is not determinable, with no signal code.

No issuer years are sealed, and the market's earliest sealed date and the start of the live record are not on the record.\n\n## Sources\n\n9 source pages are named on this page; every value above carries its own source page and read date in the numbers.\n\n- https://www.jpx.co.jp/english/markets/statistics-equities/misc/tvdivq0000001vg2-att/data_e.xlsx (identity.exchange)\n- https://mapping.gleif.org/api/v2/isin-lei/latest (identity.isin)\n- https://disclosure2dl.edinet-fsa.go.jp/searchdocument/codelist/Edinetcode.zip (identity.jurisdiction)\n- https://mapping.gleif.org/api/v2/isin-lei/latest/download (identity.lei)\n- https://mcp.jp-cm-kg.ai/events/TSE-PRIME/3864 (the disclosure lines)\n- https://www.jpx.co.jp/markets/equities/suspended/index.html (the halt flag)\n- https://disclosure2.edinet-fsa.go.jp/WZEK0040.aspx?S100YJLB (the auditor)\n- https://mcp.jp-cm-kg.ai/book/aio.json (the orderability chapter)\n- https://mcp.jp-cm-kg.ai/record/TSE-PRIME/3864 (the record)\n",
