Filing Released Lang Actions
臨時報告書
Board/Management Information Classification · 1% confidence The document is a Japanese “臨時報告書” (timely report) filed under the Financial Instruments and Exchange Act, detailing a change in the company’s representative director (management). It is not an annual or quarterly financial report but an announcement of a board/senior management change. According to our taxonomy, this falls under Board/Management Information.

確認書
Regulatory Filings Classification · 1% confidence The document is a 'Confirmation Letter' (Kakunin-sho) filed under the Financial Instruments and Exchange Act of Japan. It confirms the accuracy of the contents of a semi-annual report (Hankihokokusho) for the period ending September 30, 2025. Since this is a regulatory filing required by law to accompany financial reports but does not constitute the financial report itself, and given the specific nature of Japanese regulatory filings that do not fit into other categories, it is classified as a Regulatory Filing (RNS).

半期報告書－第80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 with the Kanto Local Finance Bureau under the Financial Instruments and Exchange Act. It contains detailed financial statements, including the balance sheet, for the interim period (April 1, 2025, to September 30, 2025). This fits the definition of an Interim/Quarterly Report (IR) as it provides comprehensive financial data and analysis for a period shorter than a full fiscal year. H1 2026

臨時報告書
AGM Information Classification · 1% confidence The document is titled with headers indicating it is a submission (提出書類: 臨時報告書 - Extraordinary Report) to the Kanto Local Finance Bureau (提出先: 関東財務局長) and is dated June 25, 2025. The content explicitly details the resolutions passed at the Annual General Meeting (株主総会が開催された年月日: 2025年6月24日), including dividend approval and director elections, along with the voting results (決議の結果). This structure perfectly matches the definition of reporting the results of a shareholder meeting, which corresponds to the AGM-R (AGM Information) code, as it reports on the outcomes of the AGM.

内部統制報告書－第79期(2024/04/01－2025/03/31)
Governance Information Classification · 1% confidence The document explicitly states in the header section (【提出書類】) that it is an "内部統制報告書" (Internal Control Report). It references the legal 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) and is submitted to the Kanto Local Finance Bureau Director (関東財務局長). The content discusses the framework, scope, criteria, and conclusion regarding the assessment of internal controls over financial reporting as of March 31, 2025. This type of report, focusing on internal controls over financial reporting, is typically filed annually in Japan, similar in function to the Sarbanes-Oxley Section 404 report in the US, which is part of the 10-K filing. However, based on the provided definitions, there is no direct equivalent for a standalone Japanese Internal Control Report. The closest related concepts are 'Audit Report / Information' (AR) or potentially 'Governance Information' (CGR). Given that this is a formal, required annual report detailing the effectiveness of internal controls over financial reporting, it is a comprehensive annual compliance document. Since '10-K' is defined as the 'Official yearly report covering company activity and full financial performance,' and this document is a critical component of that annual disclosure package (though focused specifically on internal controls), it is often grouped with major annual filings. However, 'AR' (Audit Report / Information) is defined as 'Standalone audit reports, applied accounting principles, and results of internal or regulatory stress tests (excluding full Annual Reports).' An Internal Control Report fits well within the scope of regulatory/audit-related information that is not the full 10-K. Given the highly specific nature of the Japanese filing, and lacking a direct match, 'AR' is the most appropriate fit among the choices for a formal, standalone compliance/control assessment document that is not the full annual report (10-K). The document length is 2766 characters, which is short, but the content is the report itself, not an announcement of a report, thus bypassing the RPA/RNS rule.

確認書
Audit Report / Information Classification · 1% confidence The document is titled '確認書' (Confirmation Document) and explicitly references the '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' (Annual Securities Report) for the fiscal period ending March 31, 2025. This type of confirmation statement, often filed alongside or shortly after the main annual filing, is a regulatory requirement. Since it is not the full Annual Report (10-K) itself, nor an Audit Report (AR), nor a specific management/board announcement, and it is a formal regulatory confirmation related to the annual filing, it fits best under the general 'Regulatory Filings' category (RNS) as a specific regulatory confirmation document, or potentially as a component related to the Annual Report process. Given the options, RNS serves as the best fit for miscellaneous, specific regulatory confirmations that aren't the primary reports themselves. The document length is very short (848 chars), suggesting it is an announcement or confirmation rather than a full report. FY 2025
