臨時報告書
Board/Management Information Classification · 95% confidence The document is a Japanese "臨時報告書" (timely report) filed under the Financial Instruments and Exchange Act disclosing a corporate officer change—the appointment and resignation of representative directors, along with their backgrounds and shareholdings.

確認書
Regulatory Filings Classification · 100% confidence The document is titled '確認書' (Confirmation Letter) and explicitly cites '金融商品取引法第24条の５の２第１項' (Article 24-5-2, Paragraph 1 of the Financial Instruments and Exchange Act). It serves as an officer certification confirming the accuracy of a semi-annual report. According to the 'CERTIFICATION RULE', documents that are primarily officer certifications or attestations, even if they reference a report (in this case, a semi-annual report), should be classified as Regulatory Filings (RNS) rather than the report itself.

半期報告書－第61期(2025/04/01－2026/03/31)
Interim / Quarterly Report Classification · 100% confidence The document is a '半期報告書' (Semi-Annual Report) filed under the Financial Instruments and Exchange Act of Japan. It contains comprehensive financial statements, management analysis (MD&A), and business performance data for the interim period (April 1, 2025, to September 30, 2025). As it is a formal, comprehensive financial report for a period shorter than a full fiscal year, it is classified as an Interim/Quarterly Report. H1 2026

臨時報告書
AGM Information Classification · 100% 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 filed because resolutions were passed at the "第60回定時株主総会" (60th Annual General Meeting) held on June 25, 2025. Section 2 details the resolutions, including the approval of surplus distribution, amendments to the articles of incorporation, and the election of directors and auditors, along with the vote counts (approvals, rejections, abstentions) and the required majority thresholds. This content directly relates to the official results of a shareholder vote following an AGM. Therefore, the most appropriate classification is Declaration of Voting Results & Voting Rights Announcements (DVA).

内部統制報告書－第60期(2024/04/01－2025/03/31)
Governance Information Classification · 100% confidence The document is explicitly titled "内部統制報告書" (Internal Control Report) in the cover section and throughout the text. It references the legal basis as Article 24-4-4, Paragraph 1 of the Financial Instruments and Exchange Act (金融商品取引法第24条の４の４第１項), which mandates the filing of an Internal Control Report in Japan. The content details the scope, standards (based on the Financial Accounting Standards Board's framework), evaluation procedures, and the conclusion regarding the effectiveness of internal controls over financial reporting, specifically identifying a 'significant deficiency' (重要な不備). This directly corresponds to the requirements for an Internal Control Report, which is a mandatory annual filing in Japan, often filed alongside the 10-K equivalent (Yuka Shoken Hokokusho). Given the specific Japanese regulatory context and the document's explicit content, the most appropriate classification is 'Audit Report / Information' (AR), as it deals with the assessment of internal controls related to financial reporting, which is closely related to the audit function, although a more specific Japanese equivalent might exist, 'AR' is the closest fit among the provided options for a standalone report on internal control effectiveness assessment.
