Its ISIN is not on the record, and its LEI is not on the record. Its security type is Corporate, its segment is not on the record, its sector is 3600 Machinery, and its jurisdiction is Japan (EDINET domestic filer). It is listed and not halted.\n\n## The disclosure read\n\nThe record holds 8 filings across 4 filing days in the window 2025-11-06 to 2026-11-06, comprising 1 ad hoc filing, 5 regulatory filings and 2 results filings. The median gap between filing days is 8 days. The record date is 2026-11-06, and the latest filing is dated 2026-07-08, a regulatory filing, 121 days before the record date. The Standard Market median cadence gap is 67.5 days across 1559 issuers, with a median of 7 filings and a median latency of 107 days. The 3600 Machinery median cadence gap is 32.0 days across 211 issuers, with a median of 8 filings and a median latency of 92 days.\n\n## Auditor\n\nThe auditor of record is 普賢監査法人. Its location is not on the record. Auditor changes are not on the record, as the register has no lifecycle type map yet.\n\n## Events and halts\n\nListing, delisting, name change, domicile change and segment move are not on the record, as the 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 signal null. The reason given is that the rule states a product scope and the subject's record carries no instrument class to place within it. The rule version is acm-68000/jp/suitability-principle-fiea-article-40/r1, and the chapter is as of 2026-11-04.\n\n## Coverage\n\nThe record holds no research houses named on the issuer's investor-relations page; none was found on the pages read.\n\n## Open research\n\nNo openly published research notes are on the record; none was found.\n\n## Licensed\n\nLicensed research: none loaded. A licensed row is served only to an agent whose firm holds that licence (licensor, entitlement). No licensed row is loaded.\n\n## As-of depth\n\nThe vintage is not sealed for this market, and no issuer years are sealed. The market's earliest sealed date is not on the record, and the live record began date is not on the record.\n\n## Sources\n\n7 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://disclosure2dl.edinet-fsa.go.jp/searchdocument/codelist/Edinetcode.zip (identity.jurisdiction)\n- https://mcp.jp-cm-kg.ai/events/TSE-STANDARD/7991 (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?S100YJ8W (the auditor)\n- https://mcp.jp-cm-kg.ai/book/aio.json (the orderability chapter)\n- https://mcp.jp-cm-kg.ai/record/TSE-STANDARD/7991 (the record)\n",
