In February 2008, police announced they were investigating Sahashi for aggravated breach of trust for using his position to reap profits for his affiliated company, Ginganet, which he also controlled. Ginganet sold the TV-phone sets system to Nova in addition to leasing the Ginganet-managed server for the video-phone lessons. The investigation revealed that Ginganet had illicitly received around 500 million yen in profits from Nova for the use of the server. The bankruptcy administrator had also earlier noted that the price of the TV-telephone devices Ginganet charged Nova was unreasonably high, which could have resulted in Nova losing several billion yen.
