Regulatory Filings

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 (like a semi-annual report), should be classified as Regulatory Filings (RNS) rather than the report itself.

半期報告書－第71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 management analysis for the interim period (April 1, 2025, to September 30, 2025). As it provides substantive financial data and analysis 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) and explicitly states in Section 1 that it is being filed because resolutions were passed at the "当社第70期定時株主総会" (The 70th Annual General Meeting of Shareholders). Section 2 details the resolutions, which include the appropriation of surplus (dividend) and the election of directors and a substitute audit committee director. This content directly relates to the outcomes of an Annual General Meeting (AGM). Since the document reports the *results* of the shareholder vote, the most appropriate classification is Declaration of Voting Results & Voting Rights Announcements (DVA), as it details the outcome of the resolutions voted upon at the AGM.

確認書
Audit Report / Information Classification · 98% 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 Method)'. It also explicitly mentions '金融商品取引法' (Financial Instruments and Exchange Act) and confirms the appropriateness of the '有価証券報告書' (Securities Report) for the fiscal year ending March 31, 2025. In the context of Japanese regulatory filings, a comprehensive annual report filed under the Financial Instruments and Exchange Act is equivalent to a US 10-K. Although the document itself appears to be a confirmation statement ('確認書') related to the filing, the core subject matter is the annual securities report, which aligns best with the 'Annual Report (10-K)' definition, as it pertains to the full yearly financial performance disclosure required by law, rather than just an announcement of its publication (RPA/RNS). Given the context of a major annual filing confirmation, 10-K is the most appropriate classification. FY 2025

内部統制報告書－第70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 states its basis under the Financial Instruments and Exchange Act (金融商品取引法第24条の４の４第１項). It details the scope, criteria (based on the Financial Reporting Internal Control Evaluation and Audit Standards), and the conclusion that internal controls over financial reporting are effective as of the fiscal year-end (March 31, 2025). This content directly corresponds to the requirements for an Audit Report/Information filing, specifically focusing on internal controls, which aligns best with the 'Audit Report / Information (AR)' definition, as it is a formal report on internal control effectiveness, distinct from a full Annual Report (10-K) or a simple Earnings Release (ER).
