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, specifically confirming the accuracy of the contents of a Semi-Annual Report (Hankishokokusho). Since this is a regulatory filing confirming the validity of a report rather than the report itself, and it does not fit into specific categories like 10-K or IR, it falls under the general regulatory filing category.

半期報告書－第54期(2025/04/01－2026/03/31)
Interim / Quarterly Report Classification · 100% confidence The document is a 'Semi-Annual Report' (半期報告書) filed with the Kinki Local Finance Bureau in Japan, dated November 13, 2025. It covers the interim accounting period from April 1, 2025, to September 30, 2025. It contains detailed financial statements, management analysis (MDA), and audit review information, which aligns with 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) and explicitly states in Section 1 that it is being submitted because resolutions were passed at the '定時株主総会' (Annual General Meeting) held on June 26, 2025, in accordance with financial regulations. Section 2 details the resolutions, which concern the election of directors and substitute audit committee directors, along with the voting results (votes for, against, abstentions). This content directly corresponds to reporting the outcomes of a shareholder meeting, specifically the AGM, and the voting results. Based on the definitions: - AGM-R (AGM Information): This document reports the *results* of the AGM, not just the presentation materials. - DVA (Declaration of Voting Results & Voting Rights Announcements): This is the most precise fit, as the core content is the detailed voting results for the resolutions passed at the meeting. Since the document is a formal regulatory filing reporting the specific voting outcomes of the Annual General Meeting, DVA (Declaration of Voting Results) is the most accurate classification, although AGM-R is also highly relevant. Given the explicit tabular presentation of '賛成数' (Votes For), '反対数' (Votes Against), and '決議の結果' (Resolution Result), DVA is superior to AGM-R.

Audit Report / Information Classification · 95% confidence The document is extremely short (598 characters) and appears to be a confirmation document ('確認書') related to the appropriateness of the contents of a securities report ('有価証券報告書') for the 53rd fiscal period (ending March 31, 2025). It is signed by the CEO and filed with the Kinki Local Finance Bureau Director ('近畿財務局長') based on Article 24-2, Paragraph 1 of the Financial Instruments and Exchange Act. This structure strongly suggests a certification or confirmation document accompanying a major statutory filing, likely the Annual Report (10-K equivalent in Japan, which is the Yuho). However, the document itself is not the full Annual Report, nor is it a standard Earnings Release (ER) or Interim Report (IR). Given the context of confirming the accuracy of a major annual filing, and the lack of a specific code for a 'Securities Report Confirmation,' this document functions as a regulatory filing that doesn't fit the primary report codes. Since it is a specific regulatory confirmation rather than a general announcement of a report's release (RPA) or a miscellaneous filing (RNS), I must check the definitions. It is not an Audit Report (AR), Management Discussion (MDA), or Governance Report (CGR). Because it is a specific, required regulatory confirmation document that doesn't map directly to the main report types (10-K, IR), the most appropriate fallback category is Regulatory Filings (RNS), as it is a specific regulatory submission. Revisiting the definitions: The document confirms the contents of the '有価証券報告書' (Securities Report, equivalent to 10-K). If the document *was* the 10-K, it would be '10-K'. Since it is a *confirmation* of the 10-K's accuracy, it is a specific regulatory filing. Given the options, RNS (Regulatory Filings - general regulatory announcements and fallback) is the best fit for a specific, non-standard regulatory confirmation document that isn't a standard report or announcement of a report.
