確認書
Regulatory Filings Classification · 1% confidence The document is a 'Confirmation Letter' (Kakunin-sho) filed under the Financial Instruments and Exchange Act in Japan. 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 (like a semi-annual report), should be classified as Regulatory Filings (RNS) rather than the report itself, as they do not contain the actual financial statements.

半期報告書－第132期(2025/04/01－2026/03/31)
Interim / Quarterly Report Classification · 1% confidence The document is a '半期報告書' (Semi-Annual Report) filed by Nakayama Steel Works, Ltd. with the Kanto Local Finance Bureau under the Financial Instruments and Exchange Act. It contains comprehensive financial statements, including the balance sheet, income statement, and management analysis for the interim period ending September 30, 2025. This fits the definition of an Interim/Quarterly Report (IR) as it provides substantive financial data and analysis for a period shorter than a full fiscal year. H1 2025

臨時報告書
AGM Information Classification · 1% 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 Article 24-5, Paragraph 4 of the Financial Instruments and Exchange Act, following resolutions made at the Annual General Meeting (AGM) held on June 26, 2025. Section 2 details the resolutions, including dividend approval, amendments to the articles of incorporation, and the election/re-election of directors and auditors. Crucially, Section 3 provides the detailed voting results (votes for, against, abstentions) for all proposals, including shareholder proposals. This structure—a formal report detailing the outcomes of a shareholder meeting—is characteristic of a Declaration of Voting Results & Voting Rights Announcement (DVA). While it relates to the AGM, the primary focus is reporting the *results* of the votes, not just providing the presentation materials (AGM-R) or proxy information (PSI).

内部統制報告書－第131期(2024/04/01－2025/03/31)
Governance Information Classification · 1% 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 also references the legal basis ("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) and details the scope, criteria, and results of the internal control assessment as of the fiscal year-end (2025年３月31日). This content perfectly matches the description of an Audit Report / Information filing, which covers internal control assessments, even though the primary focus is internal control rather than an external audit opinion. Given the provided definitions, 'AR' (Audit Report / Information) is the most appropriate fit for a formal internal control report required under Japanese financial regulations, as it covers 'applied accounting principles, and results of internal or regulatory stress tests' which aligns with the nature of an internal control assessment report.

有価証券報告書－第131期(2024/04/01－2025/03/31)
Annual Report Classification · 1% confidence The document is a Japanese 'Yuka Shoken Hokokusho' (Securities Report), which is the Japanese equivalent of a 10-K annual report. It contains a formal header identifying the document type, the fiscal year (131st period, 2024-04-01 to 2025-03-31), and the filing date. The presence of extensive XBRL-like metadata tags and the comprehensive nature of the filing confirm it is the full annual financial report. FY 2025

確認書
Audit Report / Information Classification · 1% confidence The document is extremely short (645 characters) and contains a table structure typical of a cover page for a Japanese regulatory filing, specifically mentioning "【提出書類】確認書" (Document Submitted: Confirmation Document) and referencing the Financial Instruments and Exchange Act ("金融商品取引法"). The content confirms that the Representative Director has verified the appropriateness of the contents of the company's 131st period Annual Securities Report ("有価証券報告書"). This document is not the Annual Report (10-K) itself, but rather a confirmation document related to it. Since there is no specific category for a 'Confirmation Document for Annual Report', and it is a formal regulatory submission confirming compliance, it best fits the general 'Regulatory Filings' (RNS) category, which serves as a fallback for miscellaneous regulatory submissions that don't fit other specific codes like ER, IR, or 10-K.
