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 titled '自己株券買付状況報告書' which translates to 'Report on Acquisition of Treasury Shares'. It references the Financial Instruments and Exchange Act Article 24-6-1 and is submitted to the Kanto Finance Bureau. The content details the number of shares acquired by the company as treasury stock during April 2026, including dates and amounts, as well as the total shares held as treasury stock at the end of the period. This is a report of the company's own share repurchases, not a general financial report or announcement. The document length is 2341 characters, which is consistent with a detailed report but not a brief announcement. Therefore, this fits the category of 'Transaction in Own Shares' (POS).

It is not the full annual report itself (10-K), nor an AGM document, dividend notice, earnings release, or other specific category. It is a regulatory filing for the FSA, and does not fit any more specific code, so it falls under the general “Regulatory Filings” category (RNS).
