Filing Released Lang Actions
訂正発行登録書
Regulatory Filings Classification · 90% confidence The document is a Japanese “訂正発行登録書” (corrected registration statement) submitted to the Kanto Finance Bureau under the Financial Instruments and Exchange Act. It is a regulatory form related to securities issuance (corporate bonds) rather than a financial report, earnings release, or other specific category. It does not contain financial statements or management discussion, nor is it a shareholder vote result, dividend notice, or merger announcement. Therefore, it falls into the fallback category of general regulatory filings (RNS).

臨時報告書
Transaction in Own Shares Classification · 92% confidence The document is a Japanese ‘臨時報告書’ filed under the Financial Instruments and Exchange Act, detailing the board resolution to dispose of the company’s own shares (treasury stock) to an employee share plan. It describes the number of shares, disposal price, and terms of the restricted share allocation – i.e., a transaction in own shares. This aligns with the ‘Transaction in Own Shares’ category (POS).

臨時報告書
Share Issue/Capital Change Classification · 92% confidence The document is a Japanese 臨時報告書 (timely disclosure report) filed under the Financial Instruments and Exchange Act, detailing the issuance of restricted stock units (RSUs) and associated share disposition numbers and prices. It describes a capital change (new share issuance to employees/subsidiary directors under an RSU plan), not a buy‐back, dividend, or earnings release. Therefore it fits the “Share Issue/Capital Change” category (Code: SHA).

臨時報告書
Transaction in Own Shares Classification · 96% confidence The document is a Japanese “臨時報告書” (Timely Report) filed under the Financial Instruments and Exchange Act, disclosing the board’s resolution to grant performance‐based share units to directors and executive officers and detailing the planned disposal of treasury shares to satisfy that grant. This is not a capital increase (no capital inclusion) but a disposal of own shares (treasury shares). Accordingly, it falls under “Transaction in Own Shares” (POS).
2026-05-11 Japanese
臨時報告書
Transaction in Own Shares Classification · 87% confidence The document is an extraordinary report (臨時報告書) filed under Japan’s Financial Instruments and Exchange Act disclosing the disposal (sale) of the company’s own shares (treasury stock) to employees under an RSU plan. It contains detailed information on share type, number disposed, disposal price, total amount, and related terms. This matches our “Transaction in Own Shares” category (Code POS), which covers reports of buybacks or disposals (issuance) of a company’s own shares. Other categories (e.g., SHA for new capital-raising issues) are less fitting since this is a treasury share disposal rather than a capital increase announcement.
