Tohoku Steel Co.,Ltd., founded in 1937, is a listed company based in Miyagi Prefecture, Japan. Its directors and officers file their transactions with EDINET (Japan FSA). Between 18 October 2025 and 18 October 2026, 4 insiders published 12 filings.
None of the filings is a plain purchase or sale on the open market; they cover grants, option exercises and other movements. 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.
Insider buying of Tohoku Steel Co.,Ltd. has been absent for the past year. Between a trade and the moment it shows up on EDINET (Japan FSA), the median delay is 7 days. That lag is the time during which only the insider knows about the trade.
Across the 3,419 companies tracked on its exchange, the median is 3 filings; at 12 filings, this issuer sits above that mark.
Every figure here comes from the filings published by EDINET (Japan FSA) and describes the past, not future prices; it is not investment advice.
