確認書
Regulatory Filings Classification · 83% confidence The document is a “確認書” (confirmation letter) submitted under the Japanese Financial Instruments and Exchange Act (金融商品取引法第24条の4の2第1項) by Taiyo Kisokogyo Co., Ltd., confirming the accuracy of its annual securities report for the 59th fiscal period (Feb 1, 2025 to Jan 31, 2026). It is not the securities report itself (which would be akin to an Annual Report or 10-K/AR) nor is it simply announcing publication or dividends, but rather a regulatory submission confirming compliance. It therefore falls under the fallback category for miscellaneous regulatory filings.
