臨時報告書
Declaration of Voting Results & Voting Rights Announcements Classification · 1% confidence The document is a 臨時報告書 (timely report) under Japan’s Financial Instruments and Exchange Act, detailing the resolutions passed at the ordinary general meeting held on April 23, 2026, and providing vote counts for each agenda item. It presents the official voting results (for, against, abstentions) for multiple proposals. This matches the definition of “Declaration of Voting Results & Voting Rights Announcements” (DVA).

確認書
Regulatory Filings Classification · 1% confidence The document is a “確認書” (confirmation letter) submitted under the Japanese Financial Instruments and Exchange Act (金融商品取引法第24条の4の2第1項) by Taiyo Kisokogyo Co., Ltd., confirming the accuracy of its annual securities report for the 59th fiscal period (Feb 1, 2025 to Jan 31, 2026). It is not the securities report itself (which would be akin to an Annual Report or 10-K/AR) nor is it simply announcing publication or dividends, but rather a regulatory submission confirming compliance. It therefore falls under the fallback category for miscellaneous regulatory filings.

有価証券報告書－第59期(2025/02/01－2026/01/31)
Annual Report Classification · 1% confidence The document is a Japanese 'Yuka Shoken Hokokusho' (Securities Report), which is the Japanese equivalent of an Annual Report (10-K). It contains formal headers, fiscal year information (59th term), and detailed financial data structures typical of an annual filing submitted to the Financial Services Agency (Tokai Finance Bureau).

確認書
Regulatory Filings Classification · 1% 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, even if they reference a specific report type, should be classified as Regulatory Filings (RNS) rather than the report itself.

半期報告書－第59期(2025/02/01－2026/01/31)
Interim / Quarterly Report Classification · 1% confidence The document is a '半期報告書' (Semi-Annual Report) filed with the Tokai Finance Bureau in Japan. It contains detailed financial statements, including the balance sheet, for the interim period ending July 31, 2025. It is a comprehensive financial report for a period shorter than a full fiscal year, fitting the definition of an Interim/Quarterly Report (IR). H1 2026

内部統制報告書－第58期(2024/02/01－2025/01/31)
Governance Information Classification · 1% confidence The document header explicitly states the filing type as "内部統制報告書" (Internal Control Report) and cites the legal basis as Article 24-4-4, Paragraph 1 of the Financial Instruments and Exchange Act ("金融商品取引法第24条の４の４第１項"). The content discusses the framework, scope, criteria, and results of the assessment of internal controls over financial reporting ("財務報告に係る内部統制"). This directly corresponds to the requirements for an Internal Control Report, which is typically filed alongside the Annual Report (10-K) in the US context, but in Japan, it is a distinct mandatory filing. Among the provided codes, 'AR' (Audit Report / Information) is the closest fit for a standalone report detailing internal control assessment results, as it covers regulatory stress tests and applied accounting principles/reports, which aligns with the nature of an internal control assessment report, even though 'Internal Control Report' is not explicitly listed. Given the comprehensive nature of the report (not just an announcement) and its focus on internal controls and financial reporting integrity, 'AR' is the most appropriate classification, as it covers standalone audit/assessment reports.
