確認書
Report Publication Announcement Classification · 1% confidence The document is a short confirmation letter (“確認書”) filed under Japan’s Financial Instruments and Exchange Act, in which the company’s president certifies that its annual securities report (“有価証券報告書” for the 94th fiscal year ending Dec 31, 2025) has been properly prepared and submitted. It does not contain the full annual report itself but simply announces/submits the report and provides inspection details. Under the “menu vs meal” rule for short notices announcing a report’s submission or availability, this is a Report Publication Announcement.

有価証券報告書－第94期(2025/01/01－2025/12/31)
Annual Report Classification · 1% confidence The document is a Japanese 'Yuka Shoken Hokokusho' (Securities Report), which is the Japanese equivalent of an Annual Report (10-K). The header explicitly identifies it as a 'Securities Report' (有価証券報告書) filed under the Financial Instruments and Exchange Act, covering a full fiscal year (2025-01-01 to 2025-12-31). It contains extensive XBRL tagging for financial statements, confirming it is the full annual report rather than an announcement. FY 94

半期報告書－第94期(2025/01/01－2025/12/31)
Interim / Quarterly Report Classification · 1% confidence The document is a '半期報告書' (Semi-Annual Report) for the company '株式会社ハマイ' (Hamai Industries Ltd.) for the period ending June 30, 2025. It contains detailed financial statements, including the balance sheet, and is filed in accordance with the Financial Instruments and Exchange Act. This fits the definition of an Interim/Quarterly Report (IR) as it provides comprehensive financial data for a period shorter than a full fiscal year. H1 2025

確認書
Regulatory Filings Classification · 1% confidence The document is a 'Confirmation Letter' (確認書) filed under the Financial Instruments and Exchange Act in Japan. It serves as an officer certification by the CEO of Hamai Industries Ltd. regarding the accuracy of the interim report for the period ending June 30, 2025. According to the 'CERTIFICATION RULE', documents that are primarily officer certifications or attestations, even if they reference a specific report type, should be classified as Regulatory Filings (RNS) rather than the report itself. H1 94

臨時報告書
AGM Information Classification · 1% confidence The document is titled '臨時報告書' (Extraordinary Report) and explicitly states in Section 1 that it is being submitted based on Article 24-5, Paragraph 4 of the Financial Instruments and Exchange Act, following the resolutions passed at the '第93回定時株主総会' (93rd Annual General Meeting) on March 25, 2025. Section 2 details the resolutions, including the approval of the dividend proposal and the election of directors. This content—reporting the results of a shareholder meeting—perfectly matches the definition of 'Declaration of Voting Results & Voting Rights Announcements' (DVA). Although it relates to an AGM, the specific filing type for reporting the *results* is DVA, not AGM-R (which is for presentations/materials). The document is a formal regulatory filing reporting the outcome of a shareholder vote.

内部統制報告書－第93期(2024/01/01－2024/12/31)
Governance Information Classification · 1% confidence The document header explicitly states the filing type as "【提出書類】 内部統制報告書" (Filing Document: Internal Control Report) and 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, detailing the assessment of internal controls over financial reporting, corresponds directly to the requirements for an Audit Report / Information filing in the provided definitions, especially since it is a standalone report on internal controls rather than the full Annual Report (10-K) or a general earnings release. The code 'AR' (Audit Report / Information) is the most appropriate fit for a formal internal control report.
