Subsidiary CYBER CONSULTANT provides digital marketing consulting, and a Green Energy business extends into solar power generation and EV charging stations by leveraging municipal relationships built through Furunavi. The company was founded in August 2007 by Tanaka Toshihiko (Chairman) and Noguchi Tetsuya (CEO), listed on TSE Mothers in 2016, upgraded to TSE First Section in July 2018, and transitioned to the Prime Market in 2022.
