After being arrested twice under suspicion of engaging in insider trading, the co-creator of Sonic the Hedgehog and other notable Sega titles has been found guilty of the offense by the Tokyo District Court.

The details:

  • As reported by the Jiji Press, the Tokyo District Court ruled that Naka's actions in purchasing shares in both Aiming and ATeam Entertainment based on inside information violated Japan's Financial Instruments and Exchange Act. In March 2023, Naka admitted to insider trading, saying there was "no doubt that I found out about the games before they were made public and bought shares in them.” In June, he was originally sentenced to two years and six months in prison.
  • He was sentenced to 30 months in prison but has been suspended for four years after he demonstrated "remorse," which means he will avoid prison as long as the suspension conditions, such as staying out of legal trouble, are met. Naka was also fined two million and 171 million yen, totaling more than one million USD. According to previous reports, the developer only made "hundreds of thousands" from his two instances of insider trading, so he'll have to dig deep into his pockets to cover the hefty fines.
  • In November 2022, Naka and former Square Enix employees Taisuke Sazaki and Fumiaki Suzuki were arrested on suspicion of insider trading after all three purchased $20,000 in stocks in developer Aiming just before it was announced that the studio was working on a new Dragon Quest title. Naka and Sazaki were arrested again a month later for similar reasons after purchasing shares in ATeam Entertainment before the public announcement of Final Fantasy VII: The First Soldier, which he later sold for around $146,000.
