2022: Insider trading charges

On November 17, 2022, Naka was arrested by the Tokyo District Public Prosecutors Office and charged with violating the Financial Instruments and Exchange Act of 2006.[59][60][61] The Public Prosecutors Office accused him of insider trading related to non-public information, with the media speculating that the arrest was related to 2020 mobile game Dragon Quest Tact.

Two other former Square Enix employees were also arrested, alleged to have bought 162,000 shares between December 2019 and February 2020 for approximately 47.2 million yen.[61][59][60]
