Nihon Univ. offices, chairman's home searched

Tokyo prosecutors have raided the offices of Nihon University, and its chairman's residence, in connection with a possible case of breach of trust.

Investigators from the Tokyo District Public Prosecutors Office on Wednesday began searching the university's head office, an office at Nihon University Enterprise Company, the home of Chairman Tanaka Hidetoshi and other places.

They suspect that a person with ties to the university caused the institution to suffer losses in connection with a contract for construction work at the university's hospital.

Nihon University has 17 colleges and schools. It also has over 73,000 students, more than any other university in Japan.

The university has four hospitals that are linked to its School of Medicine and its School of Dentistry.

Nihon University Enterprise Company was set up by the university 11 years ago to handle the procurement of supplies and equipment, as well as to supervise and operate its facilities. A private credit research firm says the company's sales topped 61 million dollars last year.

Tanaka assumed the university's top post 13 years ago. He also served as deputy head of the Japan Olympic Committee for four years through 2017.

Investigators will analyze materials they have seized to determine how money was handled at one of the largest universities in Japan.
