確認書
Regulatory Filings Classification · 100% confidence The document is a 'Confirmation Letter' (確認書) filed under Article 24-5-2, Paragraph 1 of the Financial Instruments and Exchange Act. It serves as an officer certification regarding the accuracy of a semi-annual report. According to the 'CERTIFICATION RULE', documents that are primarily officer certifications or attestations should be classified as Regulatory Filings (RNS), even if they reference a specific report type like a semi-annual report.

半期報告書－第104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, including the balance sheet, income statement, and cash flow statement for the interim period (April 1, 2025, to September 30, 2025). It is a formal regulatory filing containing substantive financial data, which fits the definition of an Interim/Quarterly Report (IR). H1 2025

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 submitted pursuant to Article 24-5, Paragraph 4 of the Financial Instruments and Exchange Act because resolutions were passed at the Annual General Meeting (AGM) held on June 25, 2025. Section 2 details the resolutions, including dividend approval, election of directors, and approval of retirement benefits for retiring directors. This structure—reporting the results of a shareholder meeting—is characteristic of a filing announcing AGM outcomes. Since the definition for AGM-R is 'Presentations and materials shared during the Annual General Meeting (AGM),' and this document reports the official results of that meeting, AGM-R is the most appropriate classification, as opposed to DEF 14A (Remuneration) or DVA (Declaration of Voting Results), although DVA is a close secondary candidate. Given the context of reporting the final outcomes of the AGM, AGM-R is selected.

内部統制報告書－第103期(2024/04/01－2025/03/31)
Governance Information Classification · 100% confidence The document is titled "内部統制報告書" (Internal Control Report) and explicitly references 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—detailing the framework, scope, procedures, and conclusion regarding internal controls over financial reporting—is characteristic of the Japanese equivalent of the Sarbanes-Oxley Section 404 report, which is a mandatory annual filing related to financial reporting integrity. While the US equivalent is often filed as part of the 10-K, in the context of Japanese regulatory filings, a standalone Internal Control Report is a distinct, comprehensive annual disclosure. Given the options, this is a comprehensive annual report focusing on internal controls, which aligns best with the scope of an Annual Report (10-K) or a specific Audit/Control Report (AR). Since it is a formal, comprehensive report covering the entire fiscal year (ending March 31, 2025) and is mandated by financial law, it is classified as a comprehensive annual filing. The closest fit among the provided codes for a comprehensive annual financial control document is 10-K, as it serves the same fundamental purpose as the annual report package, or AR if it is strictly interpreted as a standalone control audit report. Given the depth and mandatory nature, 10-K is often used for comprehensive annual filings, but AR is defined as 'Standalone audit reports, applied accounting principles, and results of internal or regulatory stress tests (excluding full Annual Reports)'. Since this is specifically an Internal Control Report, AR is a more precise fit than 10-K (which usually implies the full financial statements package). However, in many contexts, the Internal Control Report is filed alongside the 10-K. Given the options, and recognizing this as a mandatory, comprehensive annual control assessment, I will lean towards the most comprehensive annual filing category available, which is 10-K, or AR if strictly focusing on the control aspect. Since the document is a full report and not just an announcement (Rule 2), and it is a formal annual filing, I will classify it as 10-K as it represents the core annual compliance document, although AR is also plausible. Re-evaluating the definitions: 10-K is 'Official yearly report covering company activity and full financial performance.' AR is 'Standalone audit reports...'. This is an Internal Control Report. In the absence of a specific 'Internal Control Report' code, and given its annual nature, 10-K is the standard container for such reports in global databases. I will select 10-K.
