定款の一部変更に関するお知らせ
Governance Information Classification · 75% confidence The document is a timely board resolution announcement regarding proposed amendments to the company’s articles of incorporation—essentially internal governance rules—and provides the detailed changes to the charter. It is not a financial report or earnings release, nor is it a simple publication notice. The content directly relates to the company’s internal rules and governance structure, matching the “Governance Information” category rather than a proxy statement or purely regulatory fallback. Therefore, it is classified as CGR.

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 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 like an interim/semi-annual report.

半期報告書－第59期(2025/04/01－2026/03/31)
Interim / Quarterly Report Classification · 100% confidence The document is a 'Semi-Annual Report' (半期報告書) filed with the Kanto Local Finance Bureau in Japan, covering the interim accounting period from April 1, 2025, to September 30, 2025. It contains detailed financial statements, including the balance sheet, and is prepared in accordance with the Financial Instruments and Exchange Act. As it is a comprehensive financial report for a period shorter than a full fiscal year containing actual financial data, 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) and is submitted to the Kanto Local Finance Bureau. Section 1 explicitly states the reason for filing: '2025年６月19日開催の当社第58回定時株主総会において、決議事項が決議されましたので...' (Because resolutions were passed at our 58th Annual General Meeting held on June 19, 2025...). Section 2 details the resolutions passed, including dividend approval (剰余金の処分の件) and the election of directors (取締役６名選任の件). This structure—reporting the results of a shareholder meeting—is characteristic of a filing related to shareholder voting outcomes following a general meeting. While it relates to an AGM, the specific content is the official declaration of the voting results. This aligns best with the 'Declaration of Voting Results & Voting Rights Announcements' (DVA), which covers official results from shareholder votes at any general meeting.

内部統制報告書－第58期(2024/04/01－2025/03/31)
Governance Information Classification · 100% confidence The document is titled "内部統制報告書" (Internal Control Report) in the header section, which is a mandatory filing in Japan under the Financial Instruments and Exchange Act (金融商品取引法). This report details the assessment of the company's internal controls over financial reporting as of the fiscal year-end (March 31, 2025). While the content relates to internal controls, which might overlap with an Audit Report (AR), the specific nature of an 'Internal Control Report' in the Japanese regulatory context is distinct. However, among the provided English codes, 'AR' (Audit Report / Information) is the closest fit for a formal report assessing controls and principles, as there is no specific code for a standalone 'Internal Control Report'. Given the document's structure and explicit mention of internal control assessment standards, it is a formal regulatory report concerning financial integrity, making AR the most appropriate classification, although it is not a standard US 10-K or 10-Q component. The document is comprehensive, not just an announcement, ruling out RPA/RNS based on the 'MENU VS MEAL' rule.

確認書
Audit Report / Information Classification · 95% confidence The document is extremely short (577 characters) and appears to be a confirmation statement regarding the appropriateness of the contents of a securities report (有価証券報告書 - Yuuka Shouken Houkokusho). The key elements are: '【提出書類】確認書' (Filing Document: Confirmation Document), reference to the Financial Instruments and Exchange Act (金融商品取引法), and confirmation by the CEO regarding the appropriateness of the '第58期...有価証券報告書' (58th Period... Securities Report). Since this is a short confirmation document related to a major filing (the Annual Securities Report, which is equivalent to a 10-K in structure for Japanese filings), and it is not the full report itself, it fits best under the general 'Regulatory Filings' category (RNS) as a specific procedural document, or potentially an Audit Report/Information (AR) if it were an auditor's confirmation, but here it is management's confirmation. Given the options, and that it is a specific regulatory confirmation rather than a general announcement, RNS is the most appropriate fallback for specific, non-core regulatory confirmations that don't fit elsewhere. It is definitely not the 10-K itself. FY 2025
