Annual Report Classification · 100% confidence The document is identified as a Japanese 'Yuka Shoken Hokokusho' (Securities Report), which is the Japanese equivalent of the US 10-K. The header explicitly states '有価証券報告書' (Securities Report) and provides the fiscal year period (第117期, 2022-04-01 to 2023-03-31), which is the standard annual reporting requirement under the Financial Instruments and Exchange Act of Japan. The presence of XBRL tags and detailed financial metadata confirms this is the full annual report, not an announcement. FY 2023

確認書
Report Publication Announcement Classification · 100% confidence The document is a 'Confirmation Letter' (確認書) filed under the Financial Instruments and Exchange Act, specifically related to the 'Third Quarter Report' (第３四半期報告書). It serves as a formal attestation by the CEO regarding the accuracy of the quarterly report. Since it is a regulatory filing required by law to accompany the quarterly report and does not contain the financial statements themselves, it falls under the category of general regulatory filings.

四半期報告書－第117期第3四半期(2022/10/01－2022/12/31)
Interim / Quarterly Report Classification · 100% confidence The document is a 'Quarterly Report' (四半期報告書) for Riken Keiki Co., Ltd. for the third quarter of the 117th fiscal period (ending December 31, 2022). It contains detailed financial statements, including the consolidated balance sheet, income statement, and comprehensive income statement, as well as notes to the financial statements. This meets the criteria for an Interim/Quarterly Report (IR) as it provides substantive financial data and analysis for a period shorter than a full fiscal year. 9M 2023

Report Publication Announcement Classification · 100% confidence The document is a 'Confirmation Letter' (確認書) filed under the Financial Instruments and Exchange Act, specifically related to the accuracy of the Second Quarter Report (第２四半期報告書). It is a regulatory filing required by Japanese law to accompany the quarterly report, confirming the validity of the financial statements. Since it is a specific regulatory filing document that does not fit into the primary financial report categories (like 10-K or IR) and is not a mere announcement of a report, it falls under the Regulatory Filings category.
