Kaihou Co., Ltd.

Kaihou Co., Ltd. is a declared insider at 2 companies; the most frequent names are 地盤ネットホールディングス株式会社 and 株式会社ERTH Group. We count 3 filings; the first trade dates from 8 February 2026 and the latest from 30 October 2026.

The filings describe grants, exercises and other transfers rather than trades on the open market. 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.

On 9 November 2026 came the latest disclosure, a transaction in 株式会社ERTH Group. Between a trade and the moment it shows up on EDINET (Japan FSA), the median delay is 8 days. Until a filing is published, the market cannot know about the trade. Every figure here comes from the filings published by EDINET (Japan FSA) and describes the past, not future prices; it is not investment advice.
