Regulatory Filings Classification · 80% confidence The document is a brief “確認書” (confirmation letter) submitted under the Financial Instruments and Exchange Act verifying the accuracy of the company’s annual securities report (第69期有価証券報告書). It is not the full annual report itself, nor is it an announcement of publication timing. This short compliance filing does not match any specific category and thus falls under the general Regulatory Filings fallback (RNS).
