臨時報告書
Regulatory Filings Classification · 75% confidence The document is titled “臨時報告書” (Timely Disclosure Report) submitted under the Japanese Financial Instruments and Exchange Act (金融商品取引法). It announces a material impairment loss affecting financial results, and contains no full financial statements beyond the one-off event. This is a regulatory disclosure of a significant event rather than an Annual Report, Interim Report, Earnings Release, or management commentary. Therefore it falls under the catch-all “Regulatory Filings” category.

確認書
Regulatory Filings Classification · 100% confidence The document is a 'Confirmation Letter' (確認書) filed under the Financial Instruments and Exchange Act. It serves as an officer certification regarding the accuracy of a semi-annual report. According to the 'CERTIFICATION RULE', documents that are primarily officer certifications or attestations should be classified as Regulatory Filings (RNS), even if they reference a specific report type like a semi-annual report.

半期報告書－第106期(2025/04/01－2026/03/31)
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 contains detailed financial statements, including the balance sheet and income statement for the interim period (April 1, 2025, to September 30, 2025). It also includes management's analysis of financial conditions and results of operations. This fits the definition of an Interim/Quarterly Report (IR) as it provides comprehensive financial data for a period shorter than a full fiscal year. H1 2026

内部統制報告書－第105期(2024/04/01－2025/03/31)
Governance Information Classification · 100% confidence The document header explicitly states the filing type as "内部統制報告書" (Internal Control Report) and 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). Section 1 discusses the basic framework for internal controls over financial reporting, and Section 3 concludes that internal controls are deemed effective as of the end of the business year (March 31, 2025). This content directly corresponds to the requirements for an Internal Control Report, which is often filed alongside the Annual Report (10-K) but is a distinct regulatory document in Japan. Given the specific Japanese regulatory context and the content focusing entirely on the assessment of internal controls over financial reporting, the closest equivalent classification among the provided options is 'Audit Report / Information' (AR), as it covers reports on internal/regulatory stress tests and applied accounting principles, although 'Internal Control Report' is a more precise term not explicitly listed. However, since the document is a comprehensive report detailing the internal control framework and assessment results, and not merely an announcement of a report (the document length is substantial and it contains the full report content), it is classified as a formal report. 'AR' is the best fit among the choices for a standalone report on internal controls/auditing principles.

確認書
Audit Report / Information Classification · 95% confidence The document is extremely short (580 characters) and contains a header structure typical of Japanese regulatory filings, specifically mentioning "有価証券報告書" (Annual Securities Report, which corresponds to a 10-K in the US context, but this document is a confirmation). The key content is a confirmation statement ("確認書") signed by the CEO regarding the appropriateness of the contents of the company's 105th period Securities Report (covering April 1, 2024, to March 31, 2025). This is not the full 10-K itself, but a formal confirmation document related to it. Given the options, this document serves as a formal declaration or confirmation related to statutory reporting requirements. It is not a standard Earnings Release (ER), Interim Report (IR), or Audit Report (AR). Since it is a formal declaration confirming the accuracy of a major statutory filing (the Annual Securities Report), and it is not the report itself, it fits best under the general 'Regulatory Filings' (RNS) category as a specific confirmation document, or potentially as a type of Audit/Assurance document if the confirmation is regulatory in nature. However, the content is purely a CEO confirmation of the *accuracy* of the 10-K filing, which is a specific procedural step. Given the lack of a specific code for 'Confirmation of 10-K Accuracy', and its nature as a formal regulatory submission, RNS (Regulatory Filings) is the most appropriate fallback, although it is closely related to the 10-K process. Since it is a formal submission to the Kanto Local Finance Bureau Director, it is a regulatory filing. FY 2025
