The Nihon Seima Co.,Ltd: what insiders have been doing
Every trade that managers of The Nihon Seima Co.,Ltd disclose to EDINET (Japan FSA) is tracked on this page. The company sits in the Industrials sector and is based in Toyama Prefecture, Japan. It was founded in 1947. 2 insiders have disclosed 43 filings since 26 October 2025.
All open-market trades in the period are sales: 24 sales, by 1 insider, with no purchase on record. The totals do not cover 24 filings with an undisclosed amount.
The median gap between a trade and its publication by EDINET (Japan FSA) is 42 days. This delay matters because a trade only becomes useful information once it is public. Selling is not necessarily a view on the stock: liquidity needs and diversification are common motives.
Across the 3,205 companies tracked on its exchange, the median is 3 filings; at 43 filings, this issuer sits above that mark. Since 2022, the database holds 16 purchases and 25 sales by insiders of the company.
Every figure here comes from the filings published by EDINET (Japan FSA) and describes the past, not future prices; it is not investment advice.
