確認書
Audit Report / Information Classification · 95% confidence The document text contains Japanese characters and includes the header "有価証券報告書（通常方式）" which translates to 'Securities Report (Normal Format)'. It also explicitly mentions the '金融商品取引法' (Financial Instruments and Exchange Act) and confirms the accuracy of the report for the fiscal year ending March 31, 2025. A Securities Report in the Japanese regulatory context is equivalent to the comprehensive annual filing, which corresponds to the US '10-K'. Although the filing itself is a confirmation document ('確認書'), its entire purpose is to attest to the accuracy of the underlying Annual Report (Securities Report). Given the options, the content is fundamentally tied to the Annual Report structure and content verification, making '10-K' the most appropriate classification for the subject matter being confirmed, rather than a general 'RNS' or 'RPA'. The document length is very short (560 chars), suggesting it might be a cover or certification page, but the core subject is the annual filing. FY 2025

有価証券報告書－第80期(2024/04/01－2025/03/31)
Annual Report Classification · 100% confidence The document is a Japanese '有価証券報告書' (Yuuka Shouken Houkokusho), which is the standard Japanese equivalent of an Annual Report (10-K). It explicitly states the fiscal year (第80期, 2024-04-01 to 2025-03-31) and is filed with the Kinki Finance Bureau under the Financial Instruments and Exchange Act. It contains comprehensive financial data and corporate information, confirming it is the full annual report rather than an announcement or summary. FY 2025

Report Publication Announcement Classification · 100% confidence The document text contains Japanese characters and includes the title "第２四半期報告書" which translates to 'Second Quarter Report' or 'Interim Report'. It also explicitly mentions the reporting period ("第80期中（自2024年４月１日 至2024年９月30日）") and confirms the appropriateness of the filing content according to financial instruments laws, submitted to the Kinki Local Finance Bureau Director. This structure and content strongly indicate a comprehensive financial report for a period shorter than a year, which corresponds to the Interim / Quarterly Report category.

半期報告書－第80期(2024/04/01－2025/03/31)
Interim / Quarterly Report Classification · 100% confidence The document is a 'Semi-Annual Report' (半期報告書) filed by Mitsuboshi Co., Ltd. in accordance with the Financial Instruments and Exchange Act of Japan. It contains detailed financial statements, including the balance sheet, income statement, and cash flow analysis for the interim period ending September 30, 2024. As it is a comprehensive financial report for a period shorter than a full fiscal year containing actual financial data, it is classified as an Interim/Quarterly Report. H1 2025

臨時報告書
AGM Information Classification · 98% confidence The document is titled "臨時報告書" (Extraordinary Report/Timely Disclosure Report) and explicitly states in Section 1 that it is being submitted because resolutions were passed at the "第79期定時株主総会" (79th Annual General Meeting). Section 2 details the resolutions, which include the approval of the dividend distribution (剰余金の処分の件) and the election of directors (取締役選任の件). The content is a formal report detailing the results of a shareholder meeting, specifically the AGM. This aligns perfectly with the definition of AGM Information (AGM-R), which covers presentations and materials shared during the AGM. Although it reports the results, the primary context is the AGM proceedings and outcomes.

内部統制報告書－第79期(2023/04/01－2024/03/31)
Governance Information Classification · 100% confidence The document explicitly states in the header table that the filing document type is "内部統制報告書" (Internal Control Report) and cites the legal basis as "金融商品取引法第24条の４の４第１項" (Article 24-4-4, Paragraph 1 of the Financial Instruments and Exchange Act). This type of report, which assesses the effectiveness of internal controls over financial reporting, is typically filed annually in Japan, similar in function to a Sarbanes-Oxley Section 404 report in the US. Given the provided classification options, this document most closely aligns with the concept of an Audit Report/Information (AR), as it involves an assessment/evaluation of internal controls related to financial reporting, although it is not a traditional external audit opinion. However, since the document is a comprehensive report detailing the framework, scope, procedures, and conclusion regarding internal controls over financial reporting, and there is no specific code for a Japanese 'Internal Control Report', the closest fit among the options that deals with formal reporting on financial integrity/testing is 'AR' (Audit Report / Information), as it covers results of internal/regulatory stress tests and applied accounting principles/reports. Revisiting the definitions: AR is defined as 'Standalone audit reports, applied accounting principles, and results of internal or regulatory stress tests (excluding full Annual Reports)'. An Internal Control Report fits well within this scope as it is a formal report on the internal controls supporting the financial statements, distinct from the 10-K (Annual Report) itself. The document is substantial and contains the full assessment, not just an announcement.
