Former Japanese Judge Indicted for Insider Trading

On December 25, 2024, 32-year-old former Japanese judge Soichiro Sato was indicted by public prosecutors for alleged insider trading. Along with him, former Tokyo Stock Exchange employee Keito Hosomichi, 26, and his father Masato, 58, were indicted in a separate insider trading case.

Sato was charged with buying shares in about 10 companies for approximately 9.5 million yen using insider information about tender offers. This activity took place between April and early September while he was employed at the Financial Services Agency. On the other hand, Hosomichi was accused of providing undisclosed information to his father about tender offers involving three firms, enabling his father to profit by purchasing 17 million yen in shares based on that information.

Reportedly, Sato made about 4 million yen in profit from the insider trading, while the Hosomichi side generated over 3 million yen in profits. These cases highlight the serious consequences of insider trading and serve as an important reminder of the legal implications of such actions.
