Filing Released Lang Actions
確認書
Report Publication Announcement Classification · 100% confidence The document is a 'Confirmation Letter' (Kakunin-sho) filed under the Financial Instruments and Exchange Act in Japan. It specifically confirms the accuracy of the contents of the 'Interim Report' (Hankishokokusho) for the period ending September 30, 2025. Since this is a regulatory filing required to accompany financial reports but is not the report itself, and does not fit into specific categories like 'Annual Report' or 'Earnings Release', it falls under the general regulatory filing category.

半期報告書－第97期(2025/04/01－2025/09/30)
Interim / Quarterly Report Classification · 100% confidence The document is a '半期報告書' (Semi-Annual Report) for RKB Mainichi Holdings Corporation, covering the period from April 1, 2025, to September 30, 2025. It contains comprehensive financial statements, including the balance sheet, and is filed under the Financial Instruments and Exchange Act. This 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) in the header and explicitly states in Section 1 ('提出理由') that it is being submitted because resolutions were passed at the '第96回定時株主総会' (96th Annual General Meeting) held on June 27, 2025. Section 2 details the resolutions, including dividend approval and the election of directors and an auditor. This content—reporting the results of a shareholder meeting—directly corresponds to the definition of AGM Information (AGM-R) or Declaration of Voting Results & Voting Rights Announcements (DVA). Since the document focuses heavily on the voting results (votes for/against/abstain) for each resolution, DVA is the most precise fit. However, given the context of reporting the results of the Annual General Meeting, AGM-R is also highly relevant, but DVA specifically captures the 'results' aspect. Reviewing the definitions, AGM-R is for 'Presentations and materials shared during the Annual General Meeting (AGM)', while DVA is for 'Official results from shareholder votes at any general meeting (AGM or EGM)'. This document is purely the official results tabulation. Therefore, DVA is the best fit. The document length is moderate, so it is not an RPA/RNS announcement of a report, but the report itself detailing the results.

内部統制報告書－第96期(2024/04/01－2025/03/31)
Governance Information Classification · 100% 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 also references the legal basis ("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) and details the scope, criteria date (2025年3月31日), and conclusion regarding the effectiveness of internal controls over financial reporting. This content aligns perfectly with the requirements for an Audit Report / Information filing, specifically concerning internal controls, which falls under the 'AR' code in the provided definitions, as it is a standalone report on internal controls rather than the full Annual Report (10-K) or an earnings release (ER).

確認書
Audit Report / Information Classification · 95% confidence The document is extremely short (600 characters) and appears to be a confirmation document ('確認書') related to the appropriateness of the contents of the Annual Securities Report ('有価証券報告書') for the 96th fiscal period (April 1, 2024, to March 31, 2025). It is signed by the CEO and filed with the Fukuoka Local Finance Bureau. This document is not the full Annual Report (10-K) itself, nor is it a standard Earnings Release (ER) or Interim Report (IR). It is a specific regulatory confirmation required under the Financial Instruments and Exchange Act. Given the options, this type of formal confirmation or certification related to statutory filings, which is not explicitly covered by other codes (like ER, IR, 10-K), falls best under the general 'Regulatory Filings' category (RNS) as a miscellaneous, specific regulatory submission, or potentially an Audit Report/Information (AR) if it were related to stress tests, but here it is a CEO certification. Since it is a specific regulatory filing confirmation that doesn't fit the primary financial report types, RNS is the most appropriate fallback. FY 2025

有価証券報告書－第96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). The header explicitly identifies it as a 'Securities Report' (有価証券報告書) filed under the Financial Instruments and Exchange Act, covering the fiscal year from April 1, 2024, to March 31, 2025. It contains comprehensive financial data, XBRL tags, and corporate information, confirming it is the full annual filing rather than an announcement or summary. FY 2025
