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, even if they reference a specific report type, should be classified as Regulatory Filings (RNS) rather than the report itself.

半期報告書－第102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 by Mitsubishi Steel Mfg. Co., Ltd. with the Kanto Local Finance Bureau under the Financial Instruments and Exchange Act. It contains detailed financial statements, including the balance sheet, for the interim period ending September 30, 2025. This fits the definition of an Interim/Quarterly Report (IR) as it provides comprehensive financial data and analysis for a period shorter than a full fiscal year. H1 2026

内部統制報告書－第101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 ("金融商品取引法第24条の４の４第１項"). This directly corresponds to the requirements for an Internal Control Report in Japan, which is typically filed alongside the Annual Securities Report (10-K equivalent). However, based on the provided definitions, there is no specific code for a Japanese 'Internal Control Report'. The content discusses the framework, scope, standards, and conclusion regarding the effectiveness of internal controls over financial reporting as of the fiscal year-end (March 31, 2025). This type of comprehensive annual internal control assessment is most closely related to the scope and timing of a 10-K filing, but since the document is specifically about internal controls and not the full financial performance report itself, and given the lack of a specific code, we must evaluate the closest fit. The closest related concepts are 'Annual Report (10-K)' or 'Audit Report/Information (AR)'. Since this is a management assessment of internal controls, it is a mandatory component often associated with the annual filing cycle. Given the options, 'AR' (Audit Report / Information) is the best fit as it covers reports on internal/regulatory stress tests and applied accounting principles, which aligns with the nature of an internal control assessment, even though it's management's report, not an external auditor's. If '10-K' were interpreted broadly to include all major annual filings, it would be a candidate, but 'AR' captures the nature of a specific, non-financial statement report better than the general '10-K'. Since this is a specific regulatory report on internal controls, and not a general audit report, 'RNS' (Regulatory Filings) might be considered, but 'AR' is more specific to control/assessment reports. I will select 'AR' as the most appropriate category for a formal, standalone internal control assessment report.

確認書
Audit Report / Information Classification · 98% confidence The document is extremely short (622 characters) and contains a header section indicating it is a '確認書' (Confirmation Document) submitted to the Kanto Local Finance Bureau Director, referencing Article 24-4-2, Paragraph 1 of the Financial Instruments and Exchange Act. The main body explicitly states that the Representative Director and CFO have confirmed the contents of the company's '第101期（自2024年４月１日 至2025年３月31日）の有価証券報告書' (101st Fiscal Year Annual Securities Report) are appropriate. This document is not the Annual Report (10-K) itself, but rather a formal confirmation/attestation regarding the accuracy of the Annual Securities Report. Since there is no specific category for an 'Attestation of Accuracy of Annual Report,' and it is a formal regulatory filing confirming a major report, it falls best under the general 'Regulatory Filings' (RNS) category, as it is a specific regulatory submission related to the annual reporting cycle, but not the report itself. Given the context of confirming the 10-K, RNS is the most appropriate fallback. FY 2025

有価証券報告書－第101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 the US 10-K. It contains the standard header information for an annual filing, including the fiscal year (101st term, 2024-04-01 to 2025-03-31), the filing date (2025-06-19), and the regulatory basis (Financial Instruments and Exchange Act Article 24, Paragraph 1). This is a comprehensive annual financial report. FY 2025
