Report Publication Announcement Classification · 1% confidence The document is a 'Confirmation Letter' (Kakunin-sho) filed under the Financial Instruments and Exchange Act in Japan. It specifically confirms the accuracy of the contents of a Semi-Annual Report (Hankishokokusho) for the period ending September 30, 2025. Since this is a regulatory filing required to accompany financial reports and does not fit into the specific categories of the reports themselves, it falls under the general regulatory filings category.

半期報告書－第161期(2025/04/01－2026/03/31)
Interim / Quarterly Report Classification · 1% confidence The document is a '半期報告書' (Semi-Annual Report) filed by Mitsubishi Paper Mills Limited with the Kanto Local Finance Bureau. It covers the interim accounting period from April 1, 2025, to September 30, 2025. It contains detailed financial statements, management analysis (MDA), and corporate information, which aligns with the definition of an Interim/Quarterly Report (IR). H1 2026

臨時報告書
AGM Information Classification · 1% confidence The document is titled '臨時報告書' (Extraordinary Report) and explicitly states in Section 1 that it is being submitted because resolutions were passed at the '第160回定時株主総会' (160th Annual General Meeting) held on June 27, 2025. Section 2 details the resolutions, which include the election of directors and auditors, and changes to the remuneration plan. The content is a formal report detailing the results of a shareholder meeting, specifically the Annual General Meeting (AGM). This aligns perfectly with the definition of AGM Information (AGM-R), which covers presentations and materials shared during the AGM, or potentially Declaration of Voting Results & Voting Rights Announcements (DVA). Since this document details the *results* of the voting on resolutions passed at the AGM, DVA is highly specific, but AGM-R covers the general materials/results of the meeting itself. Given the comprehensive nature of reporting the resolutions and voting outcomes, AGM-R is the most appropriate primary classification for the official results filing related to the AGM.

確認書
Audit Report / Information Classification · 1% confidence The document is extremely short (590 characters) and contains a table structure typical of a cover page for a Japanese regulatory filing. Key elements include: "【提出書類】確認書" (Filing Document: Confirmation Document), "【根拠条文】金融商品取引法第24条の４の２第１項" (Legal Basis: Article 24-4-2, Paragraph 1 of the Financial Instruments and Exchange Act), and a confirmation statement by the CEO regarding the appropriateness of the "有価証券報告書" (Annual Securities Report, equivalent to 10-K) for the fiscal year ending March 31, 2025. Since this document is merely a *confirmation* of the Annual Securities Report's accuracy, and not the full report itself, it functions as a supplementary regulatory filing or certification. Given the options, it is a specific regulatory certification related to the annual filing. However, none of the codes perfectly match a 'Certification of Accuracy for 10-K'. The closest fit for a specific regulatory certification or confirmation document that isn't a full report (10-K) or an earnings release (ER) is often categorized under general Regulatory Filings (RNS) or potentially an Audit Report (AR) if it were an auditor's opinion, but here it is management's certification. Given the context of Japanese filings, this confirmation document is a mandatory attachment to the main filing. Since it is a specific, short regulatory document confirming the accuracy of the 10-K, and not the 10-K itself, RNS (Regulatory Filings) is the most appropriate fallback for a specific, non-standard regulatory certification.

内部統制報告書－第160期(2024/04/01－2025/03/31)
Governance Information Classification · 1% confidence The document header explicitly states the filing type as "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 structure and content directly correspond to the requirements for an internal control report, which is a mandatory disclosure related to financial reporting integrity. While it is a comprehensive report, it is distinct from the full Annual Report (10-K) or a standalone Audit Report (AR). In the provided definitions, the closest fit for a report detailing internal control over financial reporting, especially when it's a specific regulatory filing not covered by 10-K or AR, is often categorized under broader regulatory or audit-related disclosures. However, given the specific nature of the content (Internal Control Assessment), and comparing it against the provided list, it is most closely related to the scope covered by an Audit Report/Information (AR) or a specific regulatory filing. Since the document is the actual report detailing the assessment framework, scope, and conclusion (not an announcement of the report), it is not RPA or RNS. The content is a detailed assessment of internal controls over financial reporting, which is often bundled with or closely related to the audit process. Given the options, 'AR' (Audit Report / Information) is the most appropriate category for a formal report detailing internal control assessment standards and results, as it deals with the reliability of financial reporting controls.

有価証券報告書－第160期(2024/04/01－2025/03/31)
Annual Report Classification · 1% confidence The document is a Japanese 'Yuka Shoken Hokokusho' (Securities Report), which is the Japanese equivalent of a US 10-K. It contains the header information for the fiscal year ending March 31, 2025, and is filed with the Kanto Local Finance Bureau under the Financial Instruments and Exchange Act. Given the comprehensive nature of this filing and its role as the primary annual financial disclosure, it is classified as a 10-K. FY 2025
