The heads of 10 national universities that acquired corporate status in spring 2004 have voluntarily cut their pay in an effort to promote business efficiency, it was learned Saturday.

The heads of the Kitami Institute of Technology, Ehime University, Nagasaki University and seven others have cut their pay by up to 120,000 yen per month, university officials said.

"Acquiring corporate status forced Nagasaki University to think like a corporate entity," said an official at the university, which lowered its president's monthly salary to 1.15 million, yen down from 1.23 million yen. "We cut something that was unthinkable when we were civil servants."
