内部統制報告書－第15期(2022/04/01－2023/03/31)
Governance Information Classification · 100% confidence The document is an 'Internal Control Report' (内部統制報告書) filed under the Financial Instruments and Exchange Act (金融商品取引法). This is a specific regulatory requirement in Japan for companies to report on the effectiveness of their internal controls over financial reporting. Since it is a standalone regulatory filing regarding internal controls and does not fit into the other specific categories like 10-K or IR, it is classified as a Regulatory Filing (RNS).

確認書
Regulatory Filings Classification · 95% confidence The document is a 'Confirmation Letter' (Kakunin-sho) filed under the Financial Instruments and Exchange Act in Japan, which accompanies the Annual Securities Report (Yukashoken Hokokusho). Since it is a formal regulatory filing confirming the accuracy of the annual report and does not contain the full financial report itself, it falls under the category of general regulatory filings.

確認書
Report Publication Announcement Classification · 100% confidence The document is a 'Confirmation Letter' (Kakunin-sho) filed under the Financial Instruments and Exchange Act, specifically related to the accuracy of a Quarterly Report (第３四半期報告書). While it references a quarterly report, the document itself is a formal regulatory filing confirming the accuracy of the financial statements, which is a standard regulatory requirement in Japan. Since it is a specific regulatory filing that does not fit into the 'Interim/Quarterly Report' (IR) category (which would be the financial report itself) or other specific categories, it is best classified as a Regulatory Filing (RNS).
