確認書
Regulatory Filings Classification · 100% 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 previously filed 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69期(2025/03/21－2026/03/20)
Interim / Quarterly Report Classification · 100% confidence The document is a '半期報告書' (Semi-Annual Report) filed with the Tokai Finance Bureau under the Financial Instruments and Exchange Act. It contains comprehensive financial statements, including the balance sheet, income statement, and management analysis for the interim period (March 21, 2025, to September 20, 2025). This fits the definition of an Interim/Quarterly Report (IR) as it provides substantive financial data and analysis for a period shorter than a full fiscal year. H1 2026

臨時報告書
AGM Information Classification · 100% confidence The document is titled '臨時報告書' (Extraordinary Report) and is submitted to the '東海財務局長' (Director of the Tokai Local Finance Bureau) on June 13, 2025. Section 1 explicitly states the reason for filing is that resolutions were passed at the '定時株主総会' (Annual General Meeting) held on June 11, 2025, citing relevant Japanese financial regulations (FIEA Article 24-5(4)). Section 2 details the resolutions, which include dividend approval, amendments to the articles of incorporation (transitioning to a company with an Audit and Supervisory Committee), and the election/remuneration of directors. The content is a formal report detailing the results of a shareholder meeting, specifically the AGM resolutions and voting outcomes. This aligns perfectly with the definition of 'AGM Information' (AGM-R), which covers presentations and materials shared during the AGM, or potentially a Declaration of Voting Results (DVA). Since it details the resolutions and voting results of the AGM, AGM-R is the most appropriate primary classification, as it encompasses the voting results of the Annual General Meeting.

内部統制報告書－第68期(2024/03/21－2025/03/20)
Governance Information Classification · 100% confidence The document is titled "内部統制報告書" (Internal Control Report) and references the Financial Instruments and Exchange Act ("金融商品取引法"). It explicitly discusses the framework, scope, criteria, and results of evaluating internal controls over financial reporting ("財務報告に係る内部統制"). This structure and content strongly indicate a formal report related to internal controls, which aligns best with the Audit Report/Information category (AR), as it deals with the results of internal assessments related to financial reporting integrity, distinct from a full annual report (10-K) or a simple earnings release (ER). The document is comprehensive, not just an announcement of a report.

確認書
Audit Report / Information Classification · 95% confidence The document is extremely short (579 characters) and appears to be a confirmation document ('確認書') submitted to the Tokai Local Finance Bureau Director ('東海財務局長') on June 10, 2025. Section 1 explicitly states that the Representative Director confirmed the appropriateness of the contents of the company's 68th period Annual Securities Report ('有価証券報告書') for the period ending March 20, 2025, based on the Financial Instruments and Exchange Act. This document is not the Annual Report (10-K) itself, but rather a certification or confirmation related to it. Since there is no specific code for a 'Confirmation of Annual Report Accuracy,' and it is a regulatory filing confirming compliance related to statutory reporting, it best fits the general 'Regulatory Filings' (RNS) category, as it is a specific, short regulatory submission that doesn't match the detailed definitions of AR, 10-K, or ER.
