The chief executive officer of Teikyo University in Tokyo has resigned to take responsibility over allegations that questionable donations were taken from students seeking admission to its medical school, Teikyo officials said Wednesday.

The resignation of Shoichi Okinaga from the top post of the private university, effective the day before the announcement, and from his positions as president and trustee, effective Oct. 6, will leave him with no involvement in university affairs, they said.

Okinaga has apologized and said he resigned to take oversight responsibility for the scandal.

The officials said the post of CEO will be abolished and that Okinaga's son Yoshihito will become president.

The Education, Culture, Sports, Science and Technology Ministry announced last month that Teikyo violated a government ban on donations from students by accepting money before applicants were formally admitted to the medical school. It demanded the university return about 6.4 billion yen in government subsidies received over the past five years.

The ministry earlier said the university took in 860 million yen in donations over the past five years from students before they were formally admitted to the medical school.

Okinaga's resignation and other measures taken by the school were conveyed to the education ministry on Tuesday by four Teikyo officials.

They told ministry staff that, starting with admissions for next fiscal year, Teikyo will accept donations only after students have been admitted. Also, the university will announce successful applicants sooner, about three days after the results of admissions procedures are known.

The officials said all board members from the past five years will not receive pay for three months.
