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32期(2025/07/01－2026/06/30)
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 detailed financial statements, management analysis (MDA), and corporate information for the interim period ending December 31, 2025.

確認書
Audit Report / Information Classification · 95% confidence The document is a 'Confirmation Letter' (確認書) filed under the Financial Instruments and Exchange Act, specifically related to the accuracy of the Annual Securities Report (有価証券報告書). While it references the Annual Securities Report, the document itself is a standalone regulatory filing confirming the validity of the report's contents. Since it does not fit into the specific categories of the report itself (10-K) or a simple publication announcement (RPA), it is best classified as a general regulatory filing. FY 2025

有価証券報告書－第31期(2024/07/01－2025/06/30)
Annual Report Classification · 100% confidence The document is a Japanese 'Yuka Shoken Hokokusho' (Securities Report), which is the standard annual financial report required by the Financial Instruments and Exchange Act of Japan (Article 24, Paragraph 1). It contains comprehensive financial data, including consolidated and non-consolidated financial indicators, balance sheets, and income statements for the fiscal year ending June 30, 2025. This document is the primary annual financial filing for the company, fitting the definition of a 10-K equivalent. FY 2025

確認書
Report Publication Announcement Classification · 100% confidence The document text contains Japanese characters and includes the title "第２四半期報告書" (Second Quarter Report) and references the period "第31期中（自2024年７月１日 至2024年12月31日）" (31st term, from July 1, 2024, to December 31, 2024). This clearly indicates a comprehensive financial report covering a period shorter than a year (a half-year report). This aligns directly with the definition of an Interim / Quarterly Report (Code: IR). The document structure suggests it is the report itself, not just an announcement of its publication, despite its short length, as it contains confirmation statements regarding its appropriateness under financial regulations ("金融商品取引法令に基づき適正に記載されていることを確認しました").
