Regulatory Filings Classification · 1% confidence The document is titled '確認書' (Confirmation Letter) and explicitly cites '金融商品取引法第24条の５の２第１項' (Article 24-5-2, Paragraph 1 of the Financial Instruments and Exchange Act). It serves as an officer certification confirming 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.

Interim / Quarterly Report Classification · 1% confidence The document is a '半期報告書' (Semi-Annual Report) filed with the Kanto Local Finance Bureau in Japan. It contains comprehensive financial statements, including the balance sheet, income statement, and cash flow analysis for the interim period (April 1, 2025, to September 30, 2025). It is a formal regulatory filing containing substantive financial data, fitting the definition of an Interim/Quarterly Report (IR). H1 2026

Audit Report / Information Classification · 1% confidence The document text contains Japanese regulatory headers, specifically mentioning "有価証券報告書" (Yuka Shoken Hokokusho), which translates to 'Securities Report' or 'Annual Securities Report'. It references the Financial Instruments and Exchange Act ("金融商品取引法") and is submitted to the Kanto Local Finance Bureau ("関東財務局長"). The content confirms the accuracy of the Securities Report for the fiscal period ending March 31, 2025, signed by the CEO. In the context of US/global filings, the comprehensive annual report is typically classified as a 10-K. Since this is a Japanese regulatory filing confirming the accuracy of the annual report, and given the available codes, the closest equivalent for a comprehensive annual report is '10-K'. However, the document itself is a confirmation/attestation related to the filing, not the full report. Given the options, and the fact that it is a formal annual filing confirmation, '10-K' is the most appropriate classification for the underlying document being attested to, although 'RPA' or 'RNS' could be argued if it were merely an announcement. Since it explicitly deals with the content verification of the annual report ('有価証券報告書'), 10-K is chosen as the primary classification for the subject matter. FY 2025

内部統制報告書－第2期(2024/04/01－2025/03/31)
Governance Information Classification · 1% confidence The document is titled "内部統制報告書" (Internal Control Report) and explicitly cites the legal basis as "金融商品取引法第24条の４の４第１項" (Financial Instruments and Exchange Act Article 24-4-4, Paragraph 1). This specific filing requirement in Japan mandates the submission of an Internal Control Report, which is a key component of the annual reporting cycle, similar in function to the Sarbanes-Oxley Section 404 report in the US. Although it is a standalone report focusing on internal controls, it is a comprehensive annual assessment, distinct from a simple Audit Report (AR) or a general Earnings Release (ER). Given the specific nature of the content (assessment of internal controls over financial reporting), it aligns best with the comprehensive nature of an annual review, but since there is no direct 'Internal Control Report' code, I must select the closest fit based on the provided definitions. The content is a detailed report on internal controls, not just a brief factsheet (FS) or a management discussion (MDA). Since it is a formal, legally mandated report covering the entire fiscal year's control framework, it is most closely related to the comprehensive annual reporting structure. However, none of the codes perfectly match 'Internal Control Report'. The closest related concepts are 'Audit Report / Information' (AR) or 'Annual Report' (10-K). Since this is a specific, legally required report on internal controls, and not the full 10-K, 'AR' (Audit Report / Information) is the most appropriate category among the choices for a detailed, standalone compliance/control report, even though it is not strictly an external auditor's opinion. The document length (2294 chars) is substantial enough to be the report itself, not just an announcement (RPA/RNS).

有価証券報告書－第2期(2024/04/01－2025/03/31)
Annual Report Classification · 1% confidence The document is a Japanese 'Yuuka Shouken Houkokusho' (Annual Securities Report), which is the Japanese equivalent of a 10-K. It contains comprehensive financial statements, business descriptions, and governance information for the fiscal year ending March 31, 2025. The document is clearly the full report rather than an announcement, as evidenced by the extensive XBRL tagging and detailed financial data provided. FY 2025
