Nihonkousen

Filings by Nihonkousen span 2 companies, the busiest being 株式会社コンセック and 中国工業株式会社. We count 18 filings; the first trade dates from 26 April 2022 and the latest from 2 July 2026.

No open-market purchase or sale appears among the filings, only grants, plan transactions and other operations. Grants and option exercises follow pay plans set in advance, so they reveal less about an insider's own view than a purchase made with personal money.

The record was last updated on 28 July 2026 with a transaction in 中国工業株式会社. Typically, a trade is published a median of 8 days after it takes place. The shorter that gap, the sooner other investors can see what insiders have done. Every figure here comes from the filings published by EDINET (Japan FSA) and describes the past, not future prices; it is not investment advice.
