Sakiyama Osamu

Sakiyama Osamu (major shareholder) discloses dealings in 株式会社キューブシステム to EDINET (Japan FSA). The record holds 6 filings, for trades running from 8 December 2022 to 26 March 2026.

The newest entry dates from 2 April 2026: a transaction, in 株式会社キューブシステム. Between a trade and the moment it shows up on EDINET (Japan FSA), the median delay is 2 days. This delay matters because a trade only becomes useful information once it is public. Sales are harder to read than purchases, since they often meet personal needs such as tax or diversification. These figures are compiled from regulatory filings published by EDINET (Japan FSA). They describe what insiders did and are not a recommendation.
