確認書
Audit Report / Information Classification · 95% confidence The document is extremely short (662 characters) and contains a header section typical of Japanese regulatory filings, specifically mentioning a '確認書' (Confirmation document) submitted to the Kanto Local Finance Bureau Director based on Article 24-4-2, Paragraph 1 of the Financial Instruments and Exchange Act. The core content confirms that the Representative Director has verified the appropriateness of the contents of the company's '有価証券報告書' (Annual Securities Report) for the fiscal year ending March 31, 2025. This confirmation document itself is not the full Annual Report (10-K) or the Interim Report (IR). Since it is a specific regulatory confirmation related to the annual filing, and it is not a general announcement of a report release (RPA), it falls best under the general 'Regulatory Filings' category (RNS) as a specific, non-standard confirmation document, or potentially related to the Audit Report (AR) if it were an auditor's confirmation, but here it is management's confirmation. Given the options, RNS is the most appropriate fallback for a specific regulatory confirmation document that isn't a primary financial statement report. FY 2025

有価証券報告書－第157期(2024/04/01－2025/03/31)
Annual Report Classification · 100% confidence The document is a Japanese 'Yuka Shoken Hokokusho' (Securities Report), which is the Japanese equivalent of an Annual Report (10-K). It contains a formal header, specifies the fiscal year (157th term, April 1, 2024 to March 31, 2025), identifies the company (Rengo Co., Ltd.), and includes XBRL-style metadata tags typical of a comprehensive annual financial filing submitted to the Kanto Local Finance Bureau under the Financial Instruments and Exchange Act.

訂正発行登録書
Capital/Financing Update Classification · 98% confidence The document is titled "訂正発行登録書" (Corrected Shelf Registration Statement) and is submitted to the Kanto Local Finance Bureau ("関東財務局長"). It references a previous filing date (July 18, 2024) and an expiration date (July 25, 2026) for a shelf registration. The subject matter is related to the issuance of corporate bonds ("社債"). This type of filing, which amends or corrects a registration statement related to securities issuance (financing), falls under the category of Capital/Financing Update (CAP). Although it is a correction, the core activity is capital raising/financing.

臨時報告書
Board/Management Information Classification · 100% confidence The document is titled '臨時報告書' (Extraordinary Report) and is submitted to the Kanto Local Finance Bureau ('関東財務局長'). The core content under section '１【提出理由】' explicitly states that the submission is due to a resolution made by the Board of Directors on February 27, 2025, regarding a change in the Representative Director ('代表取締役の異動を決議いたしました'). Section '２【報告内容】' details the outgoing director, their former title ('代表取締役兼副社長執行役員'), and the effective date of the change (April 1, 2025). This content directly corresponds to the definition of 'Board/Management Information' (MANG), which covers announcements of changes in the company's board of directors or senior management.

確認書
Report Publication Announcement Classification · 100% confidence The document is extremely short (651 characters) and contains a header section typical of Japanese regulatory filings, specifically mentioning a '確認書' (Confirmation document) submitted to the '関東財務局長' (Director of the Kanto Local Finance Bureau) based on Article 24-5-2, Paragraph 1 of the Financial Instruments and Exchange Act. The core content confirms the appropriateness of the '第157期中(自 2024年４月１日 至 2024年９月30日)の半期報告書' (Semi-annual Report for the 157th Period, April 1, 2024, to September 30, 2024). Since this document is a confirmation *about* the Semi-annual Report, and not the comprehensive report itself, and given its brevity and nature as a regulatory confirmation filing, it best fits the general 'Regulatory Filings' category (RNS) or potentially an 'Interim/Quarterly Report' (IR) if it were the actual report. However, because it is explicitly a '確認書' (Confirmation) related to the semi-annual report, and not the report itself, RNS is the most appropriate fallback for a specific confirmation document that isn't explicitly defined elsewhere. Given the context of confirming a semi-annual report, IR might be considered, but RNS is safer for confirmation/miscellaneous regulatory documents.

半期報告書－第157期(2024/04/01－2025/03/31)
Interim / Quarterly Report Classification · 100% confidence The document is a '半期報告書' (Semi-Annual Report) filed with the Kanto Local Finance Bureau in Japan. It covers the interim accounting period from April 1, 2024, to September 30, 2024. It contains comprehensive financial statements, management analysis, and corporate information, which aligns with the definition of an Interim/Quarterly Report (IR). H1 2025
