Its ISIN is JP3595200001 and its LEI is 529900YSLFVJF2MDBX02. Its security type is Corporate, its segment is not on the record, and its sector is 3200 Chemicals. Its jurisdiction is Japan (EDINET domestic filer). Its listing status is listed, not halted.\n\n## The disclosure read\n\nThe record holds 21 filings in the twelve months to 2026-11-06, across 13 filing days. The median gap between filing days is 17.5 days. The latest filing is dated 2026-07-10 and is of type ad_hoc, and 119 days separate it from the record date. The Prime Market median gap is 29.0 days and its median latency is 70.0 days, across 1557 issuers. The 3200 Chemicals sector median gap is 36.5 days and its median latency is 91 days, across 202 issuers. The issuer's median filings count is recorded for both comparators as 10 on the Prime Market and 9.0 in the sector.\n\n## Auditor\n\nThe auditor of record is 有限責任 あずさ監査法人. Its location is not on the record, and the record carries no auditor changes for this issuer because this register has no lifecycle type map yet.\n\n## Events and halts\n\nThe listing, delisting, name change, domicile change and segment move lines are not on the record, because this register has no lifecycle type map yet. The halt flag shows listed, not halted.\n\n## Orderability\n\nFor Qualified Institutional Investors, the outcome is not determinable, because the rule states a product scope and the subject's record carries no instrument class to place within it. The signal is null. 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 issuer's own investor-relations page names 4 research houses: SMBC日興証券株式会社, CLSA証券株式会社, BofA証券株式会社 and モルガン・スタンレーMUFG証券株式会社.\n\n## Open research\n\nNo openly published research notes were found, so the record holds none.\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, so no issuer years are sealed and the market's earliest sealed date is not on the record. The live record began date is not on the record.\n\n## Sources\n\n10 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/4042 (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?S100YE5Q (the auditor)\n- https://mcp.jp-cm-kg.ai/book/aio.json (the orderability chapter)\n- https://www.tosoh.co.jp/ir/stocks/coverage/ (coverage)\n- https://mcp.jp-cm-kg.ai/record/TSE-PRIME/4042 (the record)\n",
