A criminal complaint was filed Tuesday against Hyogo Gov. Motohiko Saito and two others over the leak of private information relating to a whistleblower in the prefecture.

Kobe Gakuin University professor Hiroshi Kamiwaki filed the complaint with the Kobe District Public Prosecutors Office, alleging violations of the confidentiality duty under the local public service law. The complaint also targeted former Vice Gov. Yasutaka Katayama and Chiaki Inomoto, former head of the prefecture's general affairs department.

According to the complaint, Inomoto showed three prefectural assembly members in April 2024 a printed copy of the private information, which had been stored on a computer for official use. The information was regarding a former senior prefectural government official who wrote and distributed a document alleging harassment by Saito, and who died in an apparent suicide July that year.
