臨時報告書
Regulatory Filings Classification · 95% confidence The document is titled '臨時報告書' which translates to 'Extraordinary Report' or 'Special Report'. It is submitted to the financial bureau and references a significant event affecting the consolidated financial position, performance, and cash flow of the company. The content describes a specific impairment loss on investment securities recognized as a special loss, impacting the consolidated financial results for the fiscal year ending March 2026. The document is short (1041 characters) and serves as a notification of a material event affecting financial results rather than a full financial report. This matches the characteristics of a Regulatory Filing (RNS), which is a general regulatory announcement or compliance document that does not constitute a full annual or interim report. It is not an Annual Report (10-K), Interim Report (IR), nor an Earnings Release (ER) because it lacks comprehensive financial statements or key highlights. It is not a Report Publication Announcement (RPA) because it contains substantive information about the event itself, not just a notice of report availability. Therefore, the best classification is Regulatory Filings (RNS).

確認書
Regulatory Filings Classification · 100% confidence The document is titled '確認書' (Confirmation Letter) and explicitly cites '金融商品取引法第24条の５の２第１項' (Article 24-5-2, Paragraph 1 of the Financial Instruments and Exchange Act). It serves as an officer certification confirming the accuracy of a semi-annual report. 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.

半期報告書－第46期(2025/04/01－2026/03/31)
Interim / Quarterly Report Classification · 100% confidence The document is a '半期報告書' (Semi-Annual Report) filed under the Financial Instruments and Exchange Act of Japan. It contains comprehensive financial statements, including the balance sheet, income statement, and cash flow analysis for the interim period (April 1, 2025, to September 30, 2025). It is a formal regulatory filing containing substantive financial data, which fits the definition of an Interim/Quarterly Report (IR). H1 2026

臨時報告書
Regulatory Filings Classification · 100% confidence The document is explicitly titled "臨時報告書" (Extraordinary Report/Timely Disclosure Report) and is submitted to the "中国財務局長" (Director of the Kanto Local Finance Bureau). The filing reason states that an event significantly impacting the consolidated financial condition, operating results, and cash flow has occurred, citing Article 24-5, Paragraph 4 of the Financial Instruments and Exchange Act. The content details a debt waiver (債務免除) received by a subsidiary, resulting in the recognition of a debt waiver gain (債務免除益) in the consolidated financial statements for the first quarter of the fiscal year ending March 2026. This structure—a formal, timely disclosure of a significant, non-periodic financial event—is characteristic of a Japanese Extraordinary Report (or Timely Disclosure). Among the provided codes, 'RNS' (Regulatory Filings) is the most appropriate general category for miscellaneous, non-standardized regulatory disclosures that are not 10-K, IR, or ER, especially when the document is a specific Japanese regulatory filing form (Fifth Series No. 3 Form) detailing a material event. Given the specific nature of the filing (a timely disclosure of a material event under Japanese law), RNS is the best fit as a general regulatory filing category, although it is not one of the highly specific US SEC forms.
