Audit Report / Information Classification · 95% confidence The document text contains the Japanese phrase "訂正有価証券報告書" which translates to 'Amended Securities Report' or 'Correction to the Annual Securities Report'. It references the Financial Instruments and Exchange Act ("金融商品取引法") and is submitted to the Kanto Local Finance Bureau Director ("関東財務局長"). A standard US equivalent for a comprehensive annual report is the 10-K. Since this is a formal, comprehensive annual filing (even if it is a correction/amendment to one), and given the available codes, the closest match for a full annual report filing is '10-K'. The document is not a short announcement of a report's publication, but rather the content of the filing itself, confirming its contents. FY 2021

訂正有価証券報告書－第80期(2021/01/01－2021/12/31)
Annual Report Classification · 100% confidence The document is a Japanese 'Yukashoken Hokokusho' (Annual Securities Report), which is the Japanese equivalent of a 10-K. The text explicitly identifies it as an 'Annual Securities Report' (有価証券報告書) for the 80th fiscal year, covering the period from January 1, 2021, to December 31, 2021. It includes XBRL metadata and detailed corporate disclosure information, confirming it is the full annual report rather than an announcement or summary. FY 2021

Audit Report / Information Classification · 95% confidence The document text contains the Japanese phrase "訂正有価証券報告書（通常方式）" which translates to "Amended Securities Report (Normal Method)". It also references the Financial Instruments and Exchange Act ("金融商品取引法") and is submitted to the Kanto Local Finance Bureau Director ("関東財務局長"). A Securities Report in the US context is equivalent to a 10-K, but since this is a Japanese filing, and the definitions provided do not have a specific code for Japanese regulatory filings like 'Yuka Shoken Hokokusho' (which is the full annual report), we must look at the closest equivalent or the fallback. The 10-K code is defined as the "Official yearly report covering company activity and full financial performance." An Amended Securities Report is a formal, comprehensive annual filing, even if it is an amendment. Given the options, 10-K is the most appropriate classification for a comprehensive annual report filing, despite the amendment status, as it is not a short announcement (Rule 2). The document length (667 chars) is short, but the content explicitly identifies itself as a formal, legally mandated report (Securities Report), not just an announcement *about* a report, which leans towards classifying the report type itself.

訂正有価証券報告書－第79期(2020/01/01－2020/12/31)
Annual Report Classification · 100% confidence The document is a 'Correction Report' (訂正有価証券報告書) for an Annual Securities Report (有価証券報告書), which is the Japanese equivalent of a 10-K. It explicitly references the Financial Instruments and Exchange Act (金融商品取引法) and provides the fiscal year (第79期) and period (2020-01-01 to 2020-12-31). Although it is a correction, it functions as the official annual financial filing for the company. FY 2020

訂正有価証券報告書－第78期(2019/01/01－2019/12/31)
Annual Report Classification · 100% confidence The document is a Japanese 'Yukashoken Hokokusho' (Annual Securities Report), which is the Japanese equivalent of a 10-K. The header explicitly identifies it as an 'Annual Securities Report' (有価証券報告書) and includes a fiscal period (第78期, 2019-01-01 to 2019-12-31). It contains extensive XBRL tagging and financial data, confirming it is the full annual report rather than an announcement or summary. FY 2019

Report Publication Announcement Classification · 100% confidence The document text contains the header "第２四半期報告書" (Second Quarter Report) and explicitly mentions the period covered: "第83期中間期（自2024年１月１日 至2024年６月30日）" (83rd Fiscal Period Interim Period (From January 1, 2024, to June 30, 2024)). It also includes confirmation statements regarding the appropriateness of the filing content, referencing the Financial Instruments and Exchange Act ("金融商品取引法"). This structure strongly indicates a comprehensive financial report covering a period shorter than a year, which aligns with the definition of an Interim/Quarterly Report (IR). The document length is very short (651 chars), but the content is the substance of the report confirmation, not just an announcement of publication, making IR more appropriate than RPA/RNS.
