(Prime Market: 4481) — research page\n\nAs of 2026-11-06 · jp-cm-kg · record version 1\n\n## Identity and listing\n\nThe issuer is BASE CO.,LTD., listed on the Prime Market under ticker 4481. ISIN is not on the record, and LEI is not on the record. The record holds no GLEIF registration for the issuer. Security type is Corporate. Segment is not on the record. Sector is 5250 Information & Communication. Jurisdiction is Japan (EDINET domestic filer). Listing status is listed, not halted.\n\n## The disclosure read\n\nThe record holds 8 filings across 5 filing days in the window 2025-11-06 to 2026-11-06. By type, the record holds 1 ad hoc filing, 2 corporate news filings, 3 regulatory filings and 2 results filings. The median gap between filing days is 57.0 days. The latest filing is dated 2026-08-14 and is of type regulatory_filing, which is 84 days before the record date of 2026-11-06.

The sector median is 38 days for cadence, 8.0 filings and 85.0 days for latency across 644 issuers.\n\n## Auditor\n\nThe auditor of record is EY新日本有限責任監査法人. Its location is not on the record. Auditor changes are not on the record, because the market's record does not carry them.\n\n## Events and halts\n\nThe record does not carry listing, delisting, name change, domicile change or segment move events, because no lifecycle type map exists for this register. The halt flag is not set: the issuer is listed, not halted.\n\n## Orderability\n\nThe rule acm-68000/jp/suitability-principle-fiea-article-40/r1 is applied to the client category Qualified Institutional Investors.

The count is 0.\n\n## Open research\n\nNo openly published research notes were found. The count is 0.\n\n## Licensed\n\nLicensed research: none loaded.

No issuer years are sealed, and the market's earliest sealed date is not on the record. The live record began on a date 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-PRIME/4481 (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?S100XUKI (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/4481 (the record)\n",
