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, signed by the CEO and CFO to certify the accuracy of the Annual Securities Report (有価証券報告書). According to the 'CERTIFICATION RULE', documents that are primarily officer certifications or attestations, even if they reference a report, should be classified as Regulatory Filings (RNS) rather than the report itself.

有価証券報告書－第22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, including consolidated and non-consolidated financial indicators, balance sheets, and income statements for the fiscal year ending December 31, 2025. It is clearly the full report and not an announcement or summary. FY 2025

確認書
Report Publication Announcement Classification · 100% confidence The document is a 'Confirmation Letter' (Kakunin-sho) filed under Article 24-5-2 of the Financial Instruments and Exchange Act in Japan, which accompanies a semi-annual report (第２四半期報告書). Since this document is a formal regulatory filing confirming the accuracy of the interim report and does not contain the full financial statements themselves, it falls under the category of general regulatory filings.

半期報告書－第22期(2025/01/01－2025/12/31)
Interim / Quarterly Report Classification · 100% confidence The document is a '第２四半期報告書' (Quarterly Report) for the period ending June 30, 2025, filed by rakumo Inc. It contains detailed financial statements, management analysis (MDA), and corporate information as required by the Financial Instruments and Exchange Act of Japan. It is a comprehensive financial report for a period shorter than a full fiscal year, fitting the definition of an Interim/Quarterly Report (IR). H1 2025

臨時報告書
Capital/Financing Update Classification · 100% confidence The document is explicitly titled "臨時報告書" (Extraordinary Report or Timely Disclosure Report) and is submitted to the Kanto Local Finance Bureau Director ("関東財務局長"). The filing reason states it is submitted based on Article 24-5, Paragraph 4 of the Financial Instruments and Exchange Act and related cabinet office ordinance, specifically due to the conclusion of a loan agreement with financial covenants on July 1, 2025. This structure (a formal, mandatory disclosure triggered by a specific corporate event like financing) strongly suggests a regulatory filing that doesn't fit the specific categories like 10-K, ER, or IR. Since it is a mandatory, non-standard disclosure, the most appropriate general regulatory category is 'Regulatory Filings' (RNS), as it is a catch-all for required disclosures not covered by the primary forms. The document length is short (1134 chars), but it contains the full substance of the disclosure, not just an announcement of an attachment, so RPA is less likely than RNS for this type of mandatory filing.

臨時報告書
M&A Activity Classification · 100% confidence The document is titled "臨時報告書" (Extraordinary Report/Timely Disclosure Report) and is submitted to the Kanto Local Finance Bureau Director on June 30, 2025. Section 1 explicitly states the reason for filing: the resolution by the Board of Directors to acquire all shares of Startre Co., Ltd., making it a consolidated subsidiary. This action falls under the disclosure requirements for material events like M&A or significant subsidiary changes. The content details the acquisition target's financials, the acquisition price (1,015 million yen), and the expected date of change (July 1, 2025). This type of report, filed promptly upon a major corporate action (like an acquisition leading to a subsidiary change), is best classified as a general Regulatory Filing (RNS) or potentially a specific M&A filing (TAR). However, since the core event is the acquisition of a company leading to a change in control/subsidiary status, and it is a Japanese 'Extraordinary Report' (which often covers M&A), 'TAR' (M&A Activity) is a strong candidate. Given the comprehensive nature detailing the acquisition, TAR is more specific than RNS. The document length (2831 chars) is substantial enough to be the report itself, not just an announcement of a report. Since the document explicitly details the acquisition terms and target financials, it aligns with M&A Activity (TAR).
