確認書
Regulatory Filings Classification · 100% 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 confirming the accuracy of a previously filed 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 an interim/semi-annual report.

半期報告書－第67期(2025/04/01－2026/03/31)
Interim / Quarterly Report Classification · 100% confidence The document is a 'Semi-Annual Report' (半期報告書) filed by YAMAURA CORPORATION in Japan. It contains detailed financial statements, including the balance sheet and income statement, for the interim period from April 1, 2025, to September 30, 2025. It is a comprehensive financial report for a period shorter than a full fiscal year, which fits the definition of an Interim/Quarterly Report (IR). H1 2026

臨時報告書
AGM Information Classification · 100% confidence The document is titled '臨時報告書' (Extraordinary Report) in the header 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 passed, including dividend approval, director elections, and approval of the anti-takeover defense policy. The content is a formal report detailing the results of shareholder votes at a general meeting. This strongly aligns with the definition of 'Declaration of Voting Results & Voting Rights Announcements' (DVA), which covers official results from shareholder votes at any general meeting. Although it relates to the AGM, the primary function is reporting the *results* of the votes, not presenting the meeting materials (AGM-R) or soliciting votes (PSI).

確認書
Audit Report / Information Classification · 95% confidence The document is extremely short (693 characters) and contains a header section indicating it is a '確認書' (Confirmation Document) submitted to the Kanto Local Finance Bureau Director based on Article 24-8, Paragraph 1 of the Financial Instruments and Exchange Act. The main body explicitly states that the Representative Director and President, Masataka Yamaura, has confirmed the appropriateness of the contents of the company's 66th period Annual Securities Report (covering April 1, 2024, to March 31, 2025). This document is not the Annual Report (10-K) itself, but rather a formal confirmation or certification related to its filing. Since there is no specific category for a 'Confirmation of Annual Report Appropriateness,' and given its nature as a formal regulatory submission confirming compliance related to a major filing, it fits best under the general 'Regulatory Filings' (RNS) category, as it is a required regulatory submission that doesn't match the other specific definitions. It is not an Earnings Release (ER), Interim Report (IR), or Audit Report (AR). FY 2025

内部統制報告書－第66期(2024/04/01－2025/03/31)
Governance Information Classification · 100% confidence The document is titled "内部統制報告書" (Internal Control Report) in the header section, filed under the Financial Instruments and Exchange Act (金融商品取引法). It explicitly discusses the assessment and framework of internal controls over financial reporting (財務報告に係る内部統制) as of the fiscal year-end (2025年３月31日). This content aligns perfectly with the description of an Audit Report / Information filing, specifically focusing on internal control assessments, which is categorized as 'AR' in the provided schema, as it is a standalone report on internal controls rather than the full annual financial report (10-K) or a general announcement.
