2026年３月期 決算説明資料
Investor Presentation Classification · 92% confidence The document is titled “2026年3月期 決算補足説明資料” (supplementary explanatory materials for the fiscal year ending March 2026) and presents a slide‐style breakdown of full‐year financial highlights, segment results, cash flows, KPI, earnings forecast, strategic initiatives, dividend policy, and company overview. It is not a full statutory annual report (10-K) or regulatory filing; rather it is a detailed presentation of results and outlook intended for investors. This matches the definition of an Investor Presentation (IP).

確認書
Regulatory Filings Classification · 100% confidence The document is a 'Confirmation Letter' (確認書) filed under Article 24-5-2, Paragraph 1 of the Financial Instruments and Exchange Act. It serves as an officer certification regarding the accuracy of the semi-annual report. According to the 'Certification Rule', documents that are primarily officer certifications or attestations, even if they reference a specific report type (like a semi-annual report), should be classified as Regulatory Filings (RNS) rather than the report itself, as they do not contain the actual financial statements.

半期報告書－第22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, and cash flow statement 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 (IR). 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 is submitted to the "北海道財務局長" (Director of Hokkaido Local Finance Bureau). Section 1 explicitly states the reason for filing is that resolutions were passed at the "第21期定時株主総会" (21st Annual General Meeting) on June 26, 2025, pursuant to the Financial Instruments and Exchange Act. Section 2 details the resolutions, which include amendments to the Articles of Association and the election of six directors. The document provides the voting results (votes for, against, abstentions) for these resolutions. This content—reporting the results of an Annual General Meeting—perfectly matches the definition of AGM Information (AGM-R). It is not the presentation material itself, but the official report of the results.

内部統制報告書－第21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) and explicitly cites the legal basis as "金融商品取引法第24条の４の４第１項" (Financial Instruments and Exchange Act Article 24-4-4, Paragraph 1). This specific report type in Japanese regulatory filings corresponds to the assessment of internal controls over financial reporting, which is a mandatory component of the annual filing process, often associated with the 10-K equivalent in the US context, but here it is a standalone report detailing the framework, scope, procedures, and conclusion regarding internal controls. Given the provided definitions, this document is a comprehensive report detailing internal control structure and assessment results, not just a brief announcement of a report's publication (which would be RPA or RNS). While it relates to the annual cycle, it is specifically an 'Internal Control Report'. Among the options, 'AR' (Audit Report / Information) is the closest fit for a formal, comprehensive report on internal controls and testing, although '10-K' covers the full annual performance. Since this is a specific, mandatory report on internal controls, and 'AR' covers 'applied accounting principles, and results of internal or regulatory stress tests (excluding full Annual Reports)', it is the most appropriate classification for a dedicated Internal Control Report, which is a key component of the overall annual filing. However, in many classification schemes, a dedicated Internal Control Report (which is often filed alongside or as part of the 10-K/Annual Report) is sometimes categorized separately or grouped with Audit/Assurance reports. Given the strict definitions, and noting that this is a formal report on internal control effectiveness (a form of assurance/audit function), AR is selected over 10-K (which implies the full annual financial statements and MD&A) or RNS/RPA (since this is the report itself, not an announcement of it).

確認書
Audit Report / Information Classification · 98% confidence The document text contains Japanese regulatory headers such as "有価証券報告書" (Securities Report) and references to the "金融商品取引法" (Financial Instruments and Exchange Act). It includes a confirmation statement by the Representative Director and CFO regarding the appropriateness of the contents of the company's 21st period Securities Report (covering April 1, 2024, to March 31, 2025). This structure strongly indicates a formal annual filing, which corresponds to the US equivalent of a 10-K, or in this context, the comprehensive Annual Report (AR) or 10-K category. Given the explicit mention of the full annual reporting period and the confirmation of its contents, the most appropriate classification is '10-K' (Annual Report), even though the Japanese term used is slightly different, as it serves the same regulatory function as a comprehensive annual filing.
