定款一部変更に関するお知らせ
Regulatory Filings Classification · 80% confidence The document is a stock exchange disclosure announcing the Board of Directors’ resolution to propose partial amendments to the Articles of Incorporation at the upcoming 78th Annual General Meeting. It does not contain financial statements, proxy forms, or detailed AGM materials but is a regulatory announcement of corporate governance changes. This best fits the fallback category “Regulatory Filings (RNS).”

確認書
Regulatory Filings Classification · 100% confidence The document is titled '確認書' (Confirmation Letter) and explicitly references '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, even if they reference a report, should be classified as Regulatory Filings (RNS). H1 78

半期報告書－第78期(2025/04/01－2026/03/31)
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 comprehensive financial statements, including the balance sheet, income statement, cash flow statement, and notes for the interim period (April 1, 2025, to September 30, 2025). As it is a formal, comprehensive financial report for a period shorter than a full fiscal year, it is classified as an Interim/Quarterly Report. H1 2026

臨時報告書
AGM Information Classification · 100% confidence The document is titled "臨時報告書" (Extraordinary Report/Timely Disclosure Report) and explicitly states in Section 1 that it is being filed pursuant to Article 24-5, Paragraph 4 of the Financial Instruments and Exchange Act, following the resolution of matters at the Annual General Meeting (AGM) held on June 26, 2025. Section 2 details the resolutions, including the approval of the dividend (剰余金の処分の件) and the election of directors (取締役２名選任の件), along with the voting results. This structure perfectly matches the definition of reporting the results of a shareholder meeting. Since the content is the official results of the AGM, the most specific code is AGM-R (AGM Information/Results). Although it reports on voting results (DVA), AGM-R is more specific when the context is clearly the results stemming directly from the Annual General Meeting.

内部統制報告書－第77期(2024/04/01－2025/03/31)
Governance Information Classification · 100% confidence The document explicitly states in the header and body that it is an "内部統制報告書" (Internal Control Report). The basis cited is 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). This type of report, focusing on the assessment of internal controls over financial reporting, is a specific regulatory filing in Japan. While it is a comprehensive report, it is not the Annual Report (10-K) or the Interim Report (IR). In the provided classification scheme, there is no direct equivalent for a Japanese 'Internal Control Report' (which often accompanies the 10-K equivalent or standalone filing). However, given its nature as a formal, comprehensive regulatory document detailing internal controls and assessment results, it is closest in function and formality to a comprehensive report, but since it is not explicitly listed, the most appropriate general category for a formal, non-standard report that is not an ER, IR, or 10-K, but is a formal regulatory submission, is the general Regulatory Filings category (RNS). Alternatively, if we strictly interpret the content as a formal report on internal structure/governance, CGR (Governance Information) might be considered, but the explicit title points to a specific regulatory filing type. Given the strict definitions, and the lack of a specific 'Internal Control Report' code, RNS (Regulatory Filings) is the safest fallback for a formal, non-standard regulatory document. The document length (2217 chars) is substantial enough to be the report itself, not just an announcement (RPA).
