An internal investigation conducted since July at the University of Tokyo found at least?21 cases of business dealings with partner organizations that violated the university¡¯s code of ethics.

The results of the monthslong corruption probe, released Wednesday, comes after a series of bribery scandals involving faculty members at the institution were revealed last year.?

The probe found 21 cases of ethics violations, with one case still under review by the disciplinary committee.?

The most serious cases involved a specially appointed associate professor in their 40s receiving entertainment and meals worth around ?50,000 from interested parties, and another associate professor in their 30s receiving similar services of unknown amounts on three separate occasions.?

In the other 19 cases, faculty members were found to have received meals and gifts worth around ?10,000 from stakeholders.

All of the faculty members involved were reprimanded, but none were dismissed.

The probe comes after revelations last year that Shinichi Sato, then professor and practicing doctor at the University of Tokyo Hospital, had been treated to services worth around ?1.8 million at high-end clubs and brothels by the Japan Cosmetic Association, which he had been partnering with in a joint research project.

Sato, along with a former specially appointed associate professor who worked on the project, have since been indicted on bribery charges.?

Last November, Takehiro Matsubara, another doctor at the university hospital, was arrested and later indicted for spending over ?15.1 million of his research funds for personal purposes.?

A report issued by a third-party panel of lawyers last week criticized the university for its governance failures, saying its delayed response to the scandals was problematic and that its nonconfrontational stance helped build a breeding ground for misconduct among faculty.??

University President Teruo Fujii is scheduled to hold a news conference Thursday to explain how the institution plans to reform its governance system.
