半期報告書－第81期(2025/04/01－2025/09/30)
Interim / Quarterly Report Classification · 1% confidence The document is a '半期報告書' (Semi-Annual Report) filed with the Kanto Local Finance Bureau under the Financial Instruments and Exchange Act. 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). 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

確認書
Regulatory Filings Classification · 1% 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 should be classified as Regulatory Filings (RNS), even if they reference a specific report type. H1 81
2025-11-10 Japanese
臨時報告書
AGM Information Classification · 1% 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 the resolutions from the 80th Annual General Meeting (AGM) held on June 25, 2025, have been decided. Section 2 details the resolutions, including dividend approval and the election/re-election of directors and auditors. This content—reporting the official results of shareholder votes from a general meeting—directly corresponds to the definition of 'Declaration of Voting Results & Voting Rights Announcements'. The Japanese filing type is consistent with reporting the outcome of a shareholder meeting.
2025-06-30 Japanese
内部統制報告書－第80期(2024/04/01－2025/03/31)
Governance Information Classification · 1% 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 framework, scope, criteria date (March 31, 2025), and the conclusion that internal controls over financial reporting are effective. This directly corresponds to the requirements for an Internal Control Report, which is a mandatory disclosure in Japan, often filed alongside the Annual Report (10-K equivalent) or as a standalone document. Given the specific nature of this report focusing solely on internal controls over financial reporting, it aligns best with the general 'Audit Report / Information' category (AR) as it relates to assurance and control testing, although in the Japanese context, this is a distinct statutory filing. Since there is no specific code for 'Internal Control Report', and it is a comprehensive report on financial integrity assurance, AR is the closest fit among the provided options, as it covers 'applied accounting principles, and results of internal or regulatory stress tests'. It is clearly a full report, not just an announcement (RPA).

有価証券報告書－第80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 10-K annual report. It contains detailed financial statements, management indicators, and corporate information for the fiscal year ending March 31, 2025. It is a comprehensive annual filing, not an announcement or a summary. FY 2025

確認書
Audit Report / Information Classification · 1% confidence The document text contains Japanese characters and references to regulatory filings under the Financial Instruments and Exchange Act (金融商品取引法). Key phrases include '有価証券報告書' (Securities Report), '提出書類' (Filing Document) being '確認書' (Confirmation document), and referencing a specific fiscal period (2024年４月１日 至 2025年３月31日). The content is a confirmation by the CEO (代表取締役社長) regarding the appropriateness of the contents of the Securities Report for the 80th fiscal period. This confirmation document, which attests to the accuracy of a major annual filing (like a 10-K), is often filed alongside or as part of the annual reporting process. Given the context of confirming the '有価証券報告書' (Securities Report), which is the Japanese equivalent of a 10-K, and the document itself being a confirmation/attestation rather than the full report or a simple announcement, it aligns most closely with the comprehensive annual reporting structure. However, since '10-K' is specifically defined as the 'Official yearly report covering company activity and full financial performance,' and this document is a *confirmation* of that report's accuracy, it is a supporting document related to the annual filing. In the provided schema, there is no specific code for a 'Confirmation of Annual Report Filing.' The closest fit for a comprehensive annual filing document is '10-K'. If this were merely an announcement of the 10-K release, it would be RPA. Since it is a formal attestation related to the annual filing content, classifying it as the primary annual report type (10-K) is the most appropriate choice among the given options, as it is intrinsically linked to the full annual disclosure.
