臨時報告書
Share Issue/Capital Change Classification · 85% confidence The document is a Japanese "臨時報告書" (Timely Report) filed under the Financial Instruments and Exchange Act detailing a new issuance of restricted stock shares as remuneration for directors. It provides specifics on the number of shares, issue price, capital incorporation amount, and share lock-up terms—all hallmarks of a share issue/capital change announcement. This matches the "Share Issue/Capital Change" category.

有価証券報告書－第16期(2025/01/01－2025/12/31)
Annual Report Classification · 100% confidence The document is a Japanese 'Yuka Shoken Hokokusho' (Securities Report), which is the Japanese equivalent of an Annual Report (10-K). It contains the header information for the fiscal year ending December 31, 2025, and includes XBRL tagging for financial statements, confirming it is the full annual report rather than an announcement or summary.

確認書
Regulatory Filings Classification · 74% confidence The document is a Japanese ‘確認書’ (confirmation statement) filed under the Financial Instruments and Exchange Act, confirming the accuracy of the company’s annual securities report for fiscal year ending December 31, 2025. It is not the full annual report itself, nor an earnings release, proxy statement, or other specific category. It represents a regulatory compliance filing without fitting any other specific category, so it is best classified under the fallback “Regulatory Filings” (RNS).

訂正臨時報告書
M&A Activity Classification · 100% confidence The document is a 'Rinji Hokokusho' (Extraordinary Report) filed with the Kanto Local Finance Bureau in Japan. It details a specific corporate event: the acquisition of a 51% stake in 'Jiangxi Shengtai Precision Optical Co., Ltd.' by a subsidiary, making it a consolidated subsidiary. This type of regulatory filing under the Financial Instruments and Exchange Act is used for material corporate events that do not fit into standard periodic reports. Since it is a specific regulatory disclosure of a material event (M&A/subsidiary acquisition) rather than a general announcement or a report publication notice, it falls under the 'Regulatory Filings' category.

Regulatory Filings Classification · 95% confidence The document is a 'Rinji Hokokusho' (Extraordinary Report) filed with the Kanto Local Finance Bureau in Japan. It details a specific corporate event: the acquisition of a 51% stake in 'Jiangxi Shengtai Precision Optical Co., Ltd.' by a subsidiary, making it a consolidated subsidiary. This type of regulatory filing in Japan, which reports significant corporate changes (like M&A or subsidiary status changes) under the Financial Instruments and Exchange Act, is best classified as a Regulatory Filing (RNS) as it does not fit into the specific M&A (TAR) category which is typically reserved for public takeover bids or merger proposals, and it is a formal regulatory disclosure.
