臨時報告書
AGM Information Classification · 100% confidence The document is titled '臨時報告書' (Extraordinary Report) and explicitly states in Section 1 that it is being submitted because resolutions were passed at the '定時株主総会' (Annual General Meeting) held on May 21, 2025, in accordance with financial regulations. Section 2 details the resolutions passed, including dividend approval, articles of incorporation changes, and director elections, along with the voting results (votes for, against, abstentions). This content perfectly matches the description of reporting the results of a shareholder meeting. The most specific code for reporting voting results from a general meeting is 'DVA' (Declaration of Voting Results & Voting Rights Announcements). Although it relates to the AGM, the core purpose is reporting the *results* of the vote, not general AGM presentation materials (AGM-R).

内部統制報告書－第29期(2024/03/01－2025/02/28)
Governance Information Classification · 100% 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). The legal basis cited is 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 internal control reports. Section 1 discusses the framework for internal controls over financial reporting, and Section 3 concludes that the internal controls are effective as of the end of the business year (2025年２月28日). This content aligns perfectly with the requirements for an Audit Report / Information filing, specifically concerning internal control assessments, which falls under the 'AR' code in the provided definitions, as it deals with internal control testing results, distinct from a full Annual Report (10-K) or a simple Audit Report.

The document structure, including the header and the 'Corporate Information' section, confirms it is the comprehensive annual financial filing. FY 2025
