確認書
Regulatory Filings Classification · 85% confidence The document is a Japanese "確認書" (confirmation letter) under the Financial Instruments and Exchange Act, confirming the accuracy of the company’s annual securities report (有価証券報告書) for the period Jan 1–Dec 31, 2025. It is not the full annual report (10-K) itself but a required regulatory submission/attestation. Therefore it does not fit specialized categories like Annual Report or Earnings Release. It is best classified as a general regulatory filing (RNS).

有価証券報告書－第64期(2025/01/01－2025/12/31)
Annual Report Classification · 100% confidence The document is a Japanese '有価証券報告書' (Yuuka Shouken Houkokusho), which is the standard annual securities report required by the Financial Services Agency of Japan under the Financial Instruments and Exchange Act. It contains comprehensive financial statements, management discussion and analysis, and corporate information for the fiscal year ending December 31, 2025. This corresponds to the 10-K filing category in the provided schema. 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. It serves as an officer certification regarding the accuracy of a previously filed semi-annual report. Per 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64期(2025/01/01－2025/12/31)
Interim / Quarterly Report Classification · 100% confidence The document is a '半期報告書' (Semi-Annual Report) filed with the Kanto Local Finance Bureau on August 6, 2025, covering the period from January 1, 2025, to June 30, 2025. It contains detailed financial statements, management analysis (MDA), and audit review information. According to the filing definitions, a comprehensive financial report for a period shorter than a full fiscal year (such as a half-year report) containing actual financial statements is classified as an Interim/Quarterly Report (IR).

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 Director. Section 1 explicitly states the reason for filing: '2025年３月26日開催の当社第63期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 the 63rd Annual General Meeting held on March 26, 2025...). Section 2 details the resolutions, specifically regarding the '剰余金処分の件' (Resolution on Appropriation of Surplus), including the dividend amount, and provides the voting results (votes for, against, abstentions). This content perfectly matches the description of reporting the results of a shareholder vote following a general meeting. The closest specific code is DVA (Declaration of Voting Results & Voting Rights Announcements). Although it is filed as an Extraordinary Report (which might suggest RNS), the core content is the voting outcome of the AGM.

確認書
Audit Report / Information Classification · 95% confidence The document is extremely short (592 characters) and appears to be a confirmation or certification document related to the accuracy of a financial report. Key Japanese terms include: '【提出書類】確認書' (Filing Document: Confirmation Document), '金融商品取引法' (Financial Instruments and Exchange Act), and confirmation by the CEO regarding the accuracy of the '有価証券報告書' (Securities Report) for the fiscal year ending December 31, 2024. This structure strongly suggests a certification accompanying a major filing, often related to the Annual Report (10-K equivalent in Japan, which is the Yuka Shoken Hokokusho). However, since the document itself is only the confirmation, and not the full report, and given the available codes, it most closely aligns with a specific regulatory confirmation or a general regulatory filing. Since there is no specific code for a 'Confirmation of Accuracy' document, and it is a formal filing under the Financial Instruments and Exchange Act, it falls best under the general 'Regulatory Filings' (RNS) category, or potentially related to the Annual Report process. Given the explicit mention of confirming the '有価証券報告書' (Securities Report), it is a document intrinsically linked to the 10-K equivalent. However, following Rule 2 (Menu vs Meal), this is not the 10-K itself. It is a formal regulatory document. I will classify it as RNS as it is a specific regulatory confirmation document that doesn't fit the other specific categories like ER, IR, or AR, and is not an announcement of a report release (RPA).
