Annual Report Classification · 100% confidence The document is titled '有価証券報告書（通常方式）', which translates to 'Securities Report (Regular Form)', corresponding to the Japanese equivalent of an Annual Report. It references the financial period from April 1, 2025 to March 31, 2026, which is a fiscal year. The content includes confirmation statements by the president regarding the accuracy of the Securities Report as required under Financial Instruments and Exchange Act. This report is comprehensive and annual in nature, covering company activities and financials for a full fiscal year. Given the document length and detailed confirmation, it is the report itself, not just an announcement or certification letter. Therefore, the correct classification is Annual Report (10-K). FY 2026

有価証券報告書－第54期(2025/04/01－2026/03/31)
Annual Report Classification · 100% confidence The document's title and metadata clearly indicate it is a "有価証券報告書" which translates to "Securities Report" or "Annual Securities Report" under Japanese law. The filing references the financial period ending March 31, 2026, and includes extensive financial tables and detailed company information including business overview, financial data for multiple fiscal years, consolidated and non-consolidated figures. The document length is very large, and the content includes comprehensive financial statements and business discussion rather than mere announcements or summaries. This matches the characteristics of an Annual Report filing, specifically the Japanese equivalent of a Form 10-K that includes detailed annual financial and corporate information. Hence, the appropriate classification is 10-K (Annual Report). The confidence is high given the explicit indication and content consistency. FY 2026
