The president of Kappa Sushi's operating company was arrested Friday on suspicion of illegally obtaining data that was a trade secret of rival chain Hama-Sushi, the police said.
The Metropolitan Police Department believes that Kappa Create Co. President Koki Tanabe and two others -- an executive at the firm and a Hama-Sushi employee who was formerly Tanabe's subordinate -- violated the Unfair Competition Prevention Law.
The MPD also intends to send a report to the public prosecutor's office on Kappa Create's violation of the same law as a corporation.
