Filing Released Lang Actions
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 · 97% confidence The document is titled “自己株券買付状況報告書 (Report on Own Share Purchases)” filed under Article 24-6 of Japan’s Financial Instruments and Exchange Act, detailing the number of shares repurchased, disposal status, and current holdings. It is a formal regulatory report of the company’s share buyback transactions, fitting the definition of “Transaction in Own Shares” rather than an earnings release, capital change notice, or presentation. Therefore, it should be classified under POS.
2026-06-04 Japanese
Notice Regarding Completion of Cancellation of Treasury Shares
Share Issue/Capital Change Classification · 89% confidence The document is a brief corporate announcement notifying shareholders that the company has completed the cancellation of treasury shares (a capital reduction) under the Companies Act. It details the number and type of shares cancelled and the effective date. This constitutes an announcement of a capital change (share cancellation), fitting the “Share Issue/Capital Change” category rather than a buyback report or an investor presentation. Therefore, the correct classification is SHA.

自己株式の消却完了に関するお知らせ
Share Issue/Capital Change Classification · 85% confidence The document is a Japanese notice titled “自己株式の消却完了に関するお知らせ” (Notice of Completion of Cancellation of Treasury Shares) describing the cancellation of 6,250,000 ordinary shares under Article 178 of the Companies Act. This is an announcement of a capital change (cancellation of treasury stock), not a share repurchase or issuance per se. It therefore falls under Share Issue/Capital Change (Code: SHA).
2026-06-01 Japanese
訂正発行登録書
Regulatory Filings Classification · 70% confidence The document is a Japanese “訂正発行登録書” (Corrected Issuance Registration Statement) filed with the Kanto Local Finance Bureau under Japan’s Financial Instruments and Exchange Act. It is a regulatory compliance filing regarding corporate bond issuance registration, not a standard financial report (e.g., Annual Report or Interim Report) nor a press release of financial results. It does not match specialized categories like CAP (Financing Update) because it is the formal registration statement, nor IRAT (interest rate notice). Therefore it should be classified as a general regulatory filing (RNS).
2026-05-21 Japanese
臨時報告書
Transaction in Own Shares Classification · 95% confidence The document is titled “臨時報告書” and is a timely disclosure under Japan’s Financial Instruments and Exchange Act, describing the disposal of treasury shares (“自己株式処分”) to the employee shareholding plan. It details the number of shares to be disposed of, pricing, contracts, schedule, and conditions—i.e., a company’s sale/issuance of its own shares. This matches the definition for Transaction in Own Shares (POS).
