確認書
Regulatory Filings Classification · 85% confidence The document is a “確認書” (confirmation letter) submitted under Japan’s Financial Instruments and Exchange Act to the Kanto Local Finance Bureau confirming the accuracy of the company’s annual securities report (第79期有価証券報告書). It does not contain the full report itself, nor is it an AGM material, earnings release, or notice of dividend. It is a regulatory attestation/filing under local securities law, making it a miscellaneous regulatory filing. The best match from the presented categories is Regulatory Filings (RNS).

有価証券報告書－第79期(2025/01/01－2025/12/31)
Annual Report Classification · 100% confidence The document is a Japanese 'Yuka Shoken Hokokusho' (Securities Report), which is the Japanese equivalent of an Annual Report (10-K). It contains a formal header identifying the company (Keiwa Incorporated), the fiscal year (2025), and the regulatory filing basis (Financial Instruments and Exchange Act). The document includes extensive XBRL tagging for financial statements and corporate data, confirming it is the full annual report rather than an announcement or summary. FY 2025

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, Article 24-5-2, Paragraph 1. It serves as an officer certification by the CEO of KEIWA Incorporated, confirming the accuracy of the contents of the semi-annual report for the period ending June 30, 2025. Per 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.

半期報告書－第79期(2025/01/01－2025/12/31)
Interim / Quarterly Report Classification · 100% confidence The document is a 'Semi-Annual Report' (半期報告書) filed under the Financial Instruments and Exchange Act of Japan. It contains detailed financial statements, management analysis, and auditor review information for the period ending June 30, 2025. As it is a comprehensive financial report for a period shorter than a full fiscal year, it falls under the 'Interim / Quarterly Report' category. H1 2025

確認書
Audit Report / Information Classification · 95% confidence The document is extremely short (589 characters) and contains a table structure typical of Japanese regulatory filings, specifically mentioning '確認書' (Confirmation Document) and referencing the '金融商品取引法' (Financial Instruments and Exchange Act). The core content confirms that the Representative Director has verified the contents of the '有価証券報告書の訂正報告書' (Correction Report for the Annual Securities Report) for the fiscal year ending December 31, 2024, are appropriate. This document is a confirmation statement regarding the accuracy of a previously filed report (likely a 10-K equivalent or similar annual filing correction), not the full report itself. Since it is a confirmation/verification document related to a major statutory filing, and it doesn't fit perfectly into the standard US SEC codes (like 10-K), it is best classified as a general Regulatory Filing (RNS) or potentially an Audit Report/Information (AR) if the confirmation relates directly to the audit opinion. Given the context of confirming the *accuracy* of a filed report, and its brevity suggesting it's an ancillary document rather than the main report, RNS is the safest general regulatory fallback, although AR is plausible if this is a specific type of assurance statement. However, since it is a confirmation of the *accuracy* of a filed report, and not the report itself, and it is a specific regulatory submission, RNS is the most appropriate general category for non-standard regulatory confirmations.

訂正有価証券報告書－第78期(2024/01/01－2024/12/31)
Annual Report Classification · 100% 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 the fiscal year from January 1, 2024, to December 31, 2024. It contains extensive XBRL tagging and financial data, confirming it is the full annual report rather than a mere announcement. FY 2024
