確認書
Regulatory Filings Classification · 100% 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 a 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56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 with the Kinki Finance Bureau in Japan, pursuant to the Financial Instruments and Exchange Act. It contains detailed financial statements, including the balance sheet and income statement for the interim period ending September 30, 2025. As it is a comprehensive financial report for a period shorter than a full fiscal year containing substantive financial data, it is classified as an Interim/Quarterly Report. H1 2025

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 ('提出理由') that it is being submitted because resolutions were passed at the Annual General Meeting ('定時株主総会') held on June 26, 2025, in accordance with Japanese financial regulations (FSA Ordinance Article 19, Paragraph 2, Item 9-2). Section 2 ('報告内容') details the date of the meeting, the resolution (election of 7 directors), and the voting results (votes for, against, and the approval percentage). This structure—reporting the results of a shareholder meeting's resolutions—perfectly matches the definition of 'Declaration of Voting Results & Voting Rights Announcements' (DVA). Although it relates to the AGM, the content is specifically the *results* of the vote, not the presentation materials (AGM-R) or the proxy solicitation (PSI). The document length is short (1830 chars), suggesting it is an announcement/report of results rather than a comprehensive annual filing.

内部統制報告書－第55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 provision of the Financial Instruments and Exchange Act (金融商品取引法第24条の４の４第１項). It explicitly discusses the assessment 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 requirements for an Audit Report/Information filing, specifically concerning internal controls, which is categorized as 'AR' (Audit Report / Information) in the provided definitions, as it is a standalone report on internal control assessment rather than the full Annual Report (10-K) or a mere announcement of a report.
