臨時報告書
Board/Management Information Classification · 93% confidence The document is a 臨時報告書 (Timely Disclosure Report) submitted under the Financial Instruments and Exchange Act, detailing changes in the company’s representative directors (new and outgoing president positions) and their biographies. This is an announcement of changes in senior management/board positions. Hence it matches the Board/Management Information category.

確認書
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 references the 'Semi-Annual Report' (Hankishokokusho) for the period ending September 30, 2025, and confirms the accuracy of its contents. Since this is a regulatory filing required by law to accompany financial reports but is not the report itself, and does not fit into specific categories like 10-K or IR, it falls under the general regulatory filing category.

半期報告書－第127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) for Okamoto Machine Tool Works, Ltd., covering the period from April 1, 2025, to September 30, 2025. It contains detailed financial statements (balance sheets, etc.), management analysis, and business information. Under the provided definitions, a comprehensive financial report for a period shorter than a full fiscal year (like a half-year report) is classified as an Interim / Quarterly Report (IR). H1 2026

臨時報告書
AGM Information Classification · 100% confidence The document is explicitly titled "臨時報告書" (Extraordinary Report/Timely Disclosure Report) and is submitted to the Kanto Local Finance Bureau Director on July 1, 2025. Section 1 states the reason for filing is that resolutions were made at the Annual General Meeting (AGM) held on June 27, 2025, pursuant to Article 24-5, Paragraph 4 of the Financial Instruments and Exchange Act. Section 2 details the resolutions, including dividend approval, articles of incorporation changes, and the election of directors and auditors. This structure—a formal report detailing the results of a shareholder meeting (AGM)—aligns perfectly with the definition of reporting voting results and meeting outcomes. The most specific code for reporting official results from a general meeting is DVA (Declaration of Voting Results & Voting Rights Announcements). Although it is a formal filing, the content is specifically about the voting results, making DVA more precise than RNS or a general report code.

確認書
Regulatory Filings Classification · 95% 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 the company's Annual Securities Report (有価証券報告書). According to the 'Certification Rule', documents that are primarily officer certifications or attestations, even if they reference a specific report, should be classified as Regulatory Filings (RNS).

内部統制報告書－第126期(2024/04/01－2025/03/31)
Governance Information Classification · 100% confidence The document is explicitly titled "内部統制報告書" (Internal Control Report) in the header and throughout the text. It references 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 filing of an Internal Control Report in Japan. The content details the framework, scope, criteria date (March 31, 2025), evaluation procedures, and the conclusion that internal controls are effective. This directly corresponds to the requirements for an Internal Control Report, which is a specific type of regulatory filing related to financial reporting assurance, distinct from a full Annual Report (10-K) or a general Audit Report (AR). Given the specific nature of this Japanese regulatory filing, and the provided definitions, it is closest to an Audit Report/Information (AR) as it deals with the assurance/testing of internal controls over financial reporting, although it is a specific Japanese statutory report. However, since 'Internal Control Report' is not an explicit code, and it is a formal report on financial reporting integrity, 'AR' (Audit Report / Information) is the most appropriate fit among the choices, as it covers assurance results. *Self-Correction/Refinement*: While AR covers audit reports, this document is specifically an 'Internal Control Report' (J-SOX requirement). In many classification schemes, this falls under general assurance or regulatory filings. Given the options, 'AR' (Audit Report / Information) is the best fit for a document focused on the assessment and conclusion regarding the effectiveness of internal controls over financial reporting, which is closely related to auditing functions.
