確認書
Regulatory Filings Classification · 1% 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 (like a semi-annual report), should be classified as Regulatory Filings (RNS) rather than the report itself.

半期報告書－第26期(2025/04/01－2026/03/31)
Interim / Quarterly Report Classification · 1% confidence The document is a '半期報告書' (Semi-Annual Report) filed with the Kanto Local Finance Bureau in Japan, covering the period from April 1, 2025, to September 30, 2025. It contains detailed financial statements, management analysis (MD&A), and corporate information. This corresponds to the definition of an Interim/Quarterly Report (IR) as it provides comprehensive financial data for a period shorter than a full fiscal year. H1 26

臨時報告書
AGM Information Classification · 1% 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 submitted because resolutions were passed at the "第25回定時株主総会" (25th Annual General Meeting) held on June 27, 2025, in accordance with Japanese financial regulations (FIEA). The content details the resolutions passed, including the election of directors (Section 2, Item 2, Proposal 1) and capital reduction/surplus appropriation (Proposal 2), along with the voting results. Since the document reports the official results of a shareholder vote at an Annual General Meeting, the most appropriate classification is AGM-R (AGM Information/Results), as it directly relates to the outcomes of the AGM.

確認書
Audit Report / Information Classification · 1% confidence The document text contains Japanese characters and includes the header "有価証券報告書（通常方式）" which translates to "Securities Report (Normal Format)". It also explicitly mentions the submission date ("提出日"), the filing authority ("関東財務局長"), and confirms the appropriateness of the contents of the Securities Report for the fiscal year ending March 31, 2025, signed by the Representative Director and President. A Securities Report in the context of Japanese regulation is the equivalent of a comprehensive annual filing, most closely aligning with the US 10-K filing, which covers full company activity and financial performance for the year. Given the comprehensive nature implied by the title and content confirming the accuracy of the annual report, the classification should be 10-K, despite the document being a confirmation/cover sheet for that report, as it directly relates to the annual filing requirement.

内部統制報告書－第25期(2024/04/01－2025/03/31)
Governance Information Classification · 1% confidence The document is explicitly titled "内部統制報告書" (Internal Control Report) in the header and within the table structure. It references 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), which mandates the filing of an Internal Control Report by listed companies in Japan. The content discusses the framework, scope, criteria, and conclusion regarding the effectiveness of internal controls over financial reporting as of the fiscal year-end (March 31, 2025). This directly corresponds to the requirements for an Internal Control Report, which is a specific type of annual disclosure in Japan, distinct from the full 10-K or a general Audit Report (AR). Given the context of Japanese regulatory filings, this is best classified as a specialized report related to financial integrity, but since there is no specific code for 'Internal Control Report' among the provided options, I must select the closest fit or the most appropriate general category. The document is a comprehensive report detailing internal controls, not just an announcement of a report (RPA) or a general regulatory filing (RNS). However, in many classification schemes, this type of report is often grouped with Audit Reports or comprehensive annual filings. Since 'AR' is defined as 'Standalone audit reports, applied accounting principles, and results of internal or regulatory stress tests,' and this document is fundamentally about the assessment of internal controls over financial reporting, 'AR' is the most suitable category among the choices, even though it is not strictly an external auditor's opinion.

有価証券報告書－第25期(2024/04/01－2025/03/31)
Annual Report Classification · 1% confidence The document is a Japanese '有価証券報告書' (Yuuka Shouken Houkokusho), which translates to 'Annual Securities Report'. This is the standard Japanese regulatory filing equivalent to a 10-K in the US, containing comprehensive financial statements, business overviews, and management analysis for the fiscal year ending March 31, 2025. It is not an announcement or a summary, but the full report itself. FY 2025
