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 'Semi-Annual Report' (Hankishokokusho) for the period ending September 30, 2025. Since this is a regulatory filing required to accompany the interim report and does not fit into the specific categories of the report itself or other specialized categories, it is classified as a general regulatory filing.

半期報告書－第83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 Kanto Local Finance Bureau in Japan, pursuant to the Financial Instruments and Exchange Act. It contains detailed financial statements, including the balance sheet and management analysis for the interim period ending September 30, 2025. As it is a comprehensive financial report for a period shorter than a full fiscal year containing substantive financial data, it is classified as an Interim/Quarterly Report. H1 2026

内部統制報告書－第82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 cites 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 submission of internal control reports. The content discusses the framework, scope, criteria date (2025年3月31日), and the conclusion regarding the effectiveness of internal controls over financial reporting. This directly corresponds to the definition of an Audit Report / Information (AR), which covers internal or regulatory stress tests and applied accounting principles, although 'Internal Control Report' is a specific type of assurance/audit-related filing. Given the provided options, 'AR' (Audit Report / Information) is the closest fit for a formal report detailing internal control effectiveness assessment, distinct from a full annual report (10-K) or a simple earnings release (ER).

Regulatory Filings Classification · 95% confidence The document is extremely short (687 characters) and contains a header section typical of Japanese regulatory filings, specifically mentioning "有価証券報告書" (Annual Securities Report, equivalent to 10-K) and confirming its appropriateness based on the Financial Instruments and Exchange Act ("金融商品取引法"). The core content is a confirmation statement by the CEO regarding the accuracy of the company's 82nd period Annual Securities Report (covering April 1, 2024, to March 31, 2025). Since this document is a *confirmation* or *attestation* related to the Annual Report, and not the full Annual Report itself, it fits best under the general 'Regulatory Filings' category (RNS) or potentially an Audit/Attestation report (AR). However, given the context of Japanese filings, this specific confirmation document (often filed alongside or shortly after the 10-K equivalent) is a mandatory regulatory disclosure that doesn't fit the specific definitions of 10-K, ER, or IR. It is a regulatory filing confirming compliance. RNS is the most appropriate fallback for specific regulatory attestations that aren't explicitly defined elsewhere, especially when the primary document (the 10-K) is not provided.

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 based on the Financial Instruments and Exchange Act following the resolutions passed at the '第82回定時株主総会' (82nd Annual General Meeting) held on June 27, 2025. Section 2 details the resolutions passed, including changes to the articles of association and the election of directors. This content—reporting the results of a shareholder meeting—perfectly matches the definition of 'Declaration of Voting Results & Voting Rights Announcements' (DVA). Although it relates to the AGM, the primary purpose is reporting the *results* of the vote, not providing the initial AGM materials (AGM-R) or proxy information (PSI). The document length is moderate, but the content is a formal regulatory filing reporting specific voting outcomes.

有価証券報告書－第82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 comprehensive financial data, management indicators, and business information for the fiscal year ending March 31, 2025. It is a formal regulatory filing submitted to the Kanto Local Finance Bureau. FY 2025
