確認書
Regulatory Filings Classification · 1% confidence The document is a 'Confirmation Letter' (確認書) filed under the Financial Instruments and Exchange Act, Article 24-4-2, Paragraph 1. 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) rather than the report itself.

有価証券報告書－第51期(2024/10/01－2025/09/30)
Annual Report Classification · 1% confidence The document is a Japanese 'Yuuka Shouken Houkokusho' (有価証券報告書), which is the standard Japanese equivalent of an Annual Report (10-K). It contains the formal cover page, fiscal year information (第51期), and extensive XBRL-tagged financial data, confirming it is the full annual report rather than an announcement or summary. FY 2025

半期報告書－第51期(2024/10/01－2025/09/30)
Interim / Quarterly Report Classification · 1% confidence The document is a '半期報告書' (Semi-Annual Report) for Seiyu Kogyo Co., Ltd., covering the period from October 1, 2024, to March 31, 2025. It contains detailed financial statements, including the balance sheet, income statement, and comprehensive income statement, as well as management analysis of financial conditions and operating results. This fits the definition of an Interim/Quarterly Report (IR) as it provides comprehensive financial data for a period shorter than a full fiscal year. H1 2025

確認書
Report Publication Announcement Classification · 1% confidence The document text contains the title "第２四半期報告書" (Second Quarter Report) and explicitly mentions the reporting period ("第51期中（自 2024年10月１日 至 2025年３月31日）"). It also includes confirmation statements regarding the appropriateness of the filing content based on financial instruments laws, signed by the Representative Director and CFO. This structure strongly indicates a comprehensive financial report covering a period shorter than a year, which aligns with the definition of an Interim / Quarterly Report (IR). The document is not a short announcement about a report (RPA/RNS) but appears to be the core content or a cover/confirmation page of the actual report itself.

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 because resolutions were passed at the company's 50th Annual General Meeting (AGM) held on December 20, 2024, pursuant to financial regulations. Section 2 details the resolutions, which include dividend approval and the election/re-election of directors and audit committee members. This content—reporting the results of a shareholder vote at a general meeting—directly corresponds to the definition of 'Declaration of Voting Results & Voting Rights Announcements' (DVA). Although it relates to the AGM, the core purpose is reporting the *results* of the vote, not providing AGM materials (AGM-R) or proxy information (PSI).
2024-12-24 Japanese
内部統制報告書－第50期(2023/10/01－2024/09/30)
Governance Information Classification · 1% confidence The document is titled "内部統制報告書" (Internal Control Report) and explicitly references the legal basis as "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). This structure and content—detailing the framework, scope, criteria, and conclusion regarding the effectiveness of internal controls over financial reporting—is characteristic of the Japanese equivalent of the Sarbanes-Oxley Section 404 report. In the provided classification scheme, there is no direct equivalent for a Japanese 'Internal Control Report'. However, this document is a comprehensive, formal report detailing internal controls and assessment results, which is closely related to the scope of an Audit Report or comprehensive financial review documents. Given the options, 'Audit Report / Information' (AR) is the closest fit for a formal, standards-based assessment of internal controls related to financial reporting, although it is not a traditional external audit report. It is a formal regulatory filing, but RPA/RNS are less appropriate as this is the report itself, not an announcement of it. Since it is a formal report on internal controls, AR is the best available category.
