確認書
Regulatory Filings Classification · 70% confidence The document is a statutory "confirmation letter" (確認書) filed under Article 24-4-2 of Japan’s Financial Instruments and Exchange Act, certifying the accuracy of the company’s annual securities report. It is not the full annual report itself, nor an earnings release, proxy statement, or any other specific category, and it doesn’t announce a shareholder vote or dividend. Therefore, it falls into the general regulatory announcement/fallback category.

有価証券報告書－第11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 Japanese equivalent of an Annual Report (10-K). It contains comprehensive financial data, management indicators, and business information for the fiscal year ending December 31, 2025. It is clearly a full annual report rather than an announcement or a summary. FY 2025

自己株券買付状況報告書（法２４条の６第１項に基づくもの）
Transaction in Own Shares Classification · 100% confidence The document is a '自己株券買付状況報告書' (Report on Status of Purchase of Own Shares) filed with the Kanto Local Finance Bureau under the Financial Instruments and Exchange Act. It details the company's (MRSO Inc.) share buyback activity for the period of August 2025, including the number of shares acquired and the total cost. This aligns perfectly with the definition for 'Transaction in Own Shares' (POS).

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 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, as they do not contain the actual financial statements. H1 2025

半期報告書－第11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 under the Financial Instruments and Exchange Act. It contains comprehensive financial statements, including the balance sheet, income statement, and cash flow analysis for the period from January 1, 2025, to June 30, 2025. As it is a formal, comprehensive interim financial report containing actual financial data, it is classified as an Interim/Quarterly Report (IR). H1 2025

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 ('関東財務局長'). The content explicitly details the resolutions passed ('決議事項') at the Annual General Meeting ('定時株主総会') held on March 27, 2025, including changes to the articles of incorporation (transitioning to an audit and supervisory committee company structure) and the election/remuneration of directors. This structure—reporting the results of a shareholder meeting—is characteristic of an AGM-related filing. Since it reports the *results* of the vote rather than being a presentation (AGM-R) or a proxy solicitation document (DEF 14A/PSI), and it specifically details voting outcomes, it aligns best with the category for Declaration of Voting Results & Voting Rights Announcements (DVA). Although it is a formal regulatory filing, DVA is more specific than the general RNS fallback.
