確認書
Regulatory Filings Classification · 85% confidence The document is a “確認書” (confirmation letter) under the Financial Instruments and Exchange Act, confirming that the half-year report contents are correct. It contains no actual financial statements or substantive data but is an officer certification. Under the Certification Rule, such confirmation letters are classified as Regulatory Filings (RNS), not as the half-year Interim Report itself.

半期報告書－第25期(2025/10/01－2026/09/30)
Interim / Quarterly Report Classification · 92% confidence The document is the actual semi-annual financial report (‘半期報告書’) filed under Japan’s Financial Instruments and Exchange Act Article 24-5 for the period October 1, 2025 to March 31, 2026. It contains full interim consolidated financial statements (balance sheet, income statement, cash flows), management’s discussion and analysis, segment results, risk factors, Notes, and audit review information—not merely an announcement or link to a report. This matches the definition of an Interim/Quarterly Report (IR). H1 2026

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, Article 24-4-2, Paragraph 1. This is a mandatory internal control and accuracy certification document that accompanies the Annual Securities Report (Yuuka Shouken Houkokusho) in Japan. Since it is a regulatory filing confirming the accuracy of the annual report and does not constitute the annual report itself, it falls under the general regulatory filings category. FY 2025

有価証券報告書－第24期(2024/10/01－2025/09/30)
Annual Report Classification · 100% confidence The document is a Japanese 'Yuka Shoken Hokokusho' (Securities Report), which is the Japanese equivalent of a 10-K annual report. It contains the cover page, business information, and financial indicators for the fiscal year ending September 30, 2025. The document structure, including the 'Financial Information' section and XBRL tags, confirms it is the full annual financial filing. FY 2025

半期報告書－第24期(2024/10/01－2025/09/30)
Interim / Quarterly Report Classification · 100% confidence The document is a '第２四半期報告書' (Second Quarter Report) for Fixstars Corporation, covering the period from October 1, 2024, to March 31, 2025. It contains detailed financial statements (balance sheet, income statement, cash flow analysis) and management discussion. 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 · 100% confidence The document text is extremely short (574 characters) and contains a header indicating "第２四半期報告書" (Second Quarter Report) and a submission date of May 14, 2025. The content confirms the appropriateness of the '半期報告書' (Half-Year Report) for the period ending March 31, 2025, signed by the CEO and CFO, and submitted to the Kanto Local Finance Bureau Director, referencing Article 24-5-2, Paragraph 1 of the Financial Instruments and Exchange Act. This structure strongly suggests a formal confirmation or cover sheet accompanying a comprehensive periodic report, rather than the full report itself. Since it pertains to a comprehensive report for a period shorter than a year (half-year), the underlying document is an Interim/Quarterly Report (IR). However, given the brevity and the nature of the text being a confirmation/cover page referencing the filing of the '半期報告書', it fits the criteria for a Report Publication Announcement (RPA) or a general Regulatory Filing (RNS) under the 'MENU VS MEAL' rule, as it is not the full report. Since 'IR' (Interim/Quarterly Report) is a specific category for the comprehensive report, and this document is the formal confirmation/submission wrapper, 'RPA' (Report Publication Announcement) is a strong candidate if it were just announcing the filing. However, the content is a formal certification ('確認書') regarding the accuracy of the '半期報告書' (Half-Year Report). In Japanese regulatory filings, the formal submission document confirming the accuracy of a periodic report (like a 10-Q equivalent) is often classified based on the underlying report type if it contains substantive confirmation, or as a general regulatory filing. Given the explicit mention of the '半期報告書' (Half-Year Report) and the confirmation of its contents, the most accurate classification for the *substance* being addressed is the Interim/Quarterly Report (IR). If this were purely an announcement stating 'The IR is attached,' RPA would be better. Since it is the formal certification document for the IR, IR is chosen as the primary classification for the subject matter being certified, although RPA is a close secondary possibility due to length. I will classify it as IR because the core subject is the certification of the Half-Year Report.
