確認書
Regulatory Filings Classification · 100% confidence The document is titled '確認書' (Confirmation Letter) and explicitly cites '金融商品取引法第24条の５の２第１項' (Article 24-5-2, Paragraph 1 of the Financial Instruments and Exchange Act). It serves as an officer certification confirming 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.

半期報告書－第50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) filed under the Financial Instruments and Exchange Act of Japan. It contains comprehensive financial statements, including the balance sheet, income statement, and cash flow statement for the interim period (April 1, 2025, to September 30, 2025). It is a substantive financial report rather than an announcement or certification, fitting the definition of an Interim/Quarterly Report (IR). H1 2026

訂正臨時報告書
Regulatory Filings Classification · 100% confidence The document is a 'Rinji Hokokusho' (Extraordinary Report) filed with the Kanto Local Finance Bureau in Japan. It details the establishment of a new subsidiary (KOIKEYA AMERICA INC.) and its classification as a 'specified subsidiary' (tokutei kogaisha) under the Financial Instruments and Exchange Act. Since this is a regulatory filing regarding corporate structure changes that does not fit into specific categories like M&A or Board changes, it is classified as a Regulatory Filing (RNS).

臨時報告書
AGM Information Classification · 100% confidence The document is titled "臨時報告書" (Extraordinary Report/Timely Disclosure Report) and explicitly states in Section 1 that it is being filed pursuant to Article 24-5, Paragraph 4 of the Financial Instruments and Exchange Act, following the resolutions passed at the Annual General Meeting (AGM) held on June 19, 2025. Section 2 details the resolutions, which concern the election of directors and audit committee members. This structure—a formal filing reporting the results of a shareholder meeting—aligns perfectly with the definition of reporting voting results from a general meeting. The specific code for this is Declaration of Voting Results & Voting Rights Announcements (DVA). Although it relates to the AGM, the core content is the voting outcome report, not the AGM presentation itself (AGM-R).

確認書
Audit Report / Information Classification · 95% confidence The document text contains Japanese characters and includes the header "有価証券報告書（通常方式）" which translates to 'Securities Report (Normal Method)'. It explicitly mentions the submission date ('提出日': 2025年６月20日), the filing basis ('根拠条文': 金融商品取引法第24条の４の２第１項 - Financial Instruments and Exchange Act Article 24-4-2 Paragraph 1), and confirms the accuracy of the contents of the Securities Report for the 49th fiscal period (ending March 31, 2025). A Securities Report in the context of Japanese regulation (EDINET) is the equivalent of the US 10-K filing, which is the official yearly report covering company activity and full financial performance. Although the document itself appears to be a confirmation statement ('確認書') related to the filing, the core subject matter is the annual audited financial report (Securities Report). Given the provided definitions, the closest match for a comprehensive annual report is '10-K'. Since this is a confirmation *of* the annual report, and not the report itself, it could potentially be RNS or RPA, but the content is so intrinsically tied to the annual filing that 10-K is the most appropriate classification for the underlying document type being referenced and confirmed.
