The University of Tokyo remained Asia's No. 1 institution of higher education, according to an annual international ranking released Wednesday, but other Japanese universities lost ground.

The country's most prestigious university, known colloquially as Todai, held steady in 23rd place in the Times Higher Education World University Rankings for 2014-15.

But four other Japanese universities that made the top-200 list dropped in the rankings. Kyoto University fell seven places to 59th, while the Tokyo Institute of Technology dropped to 141st from 125th. Osaka University slipped to 157th from 144th, and Tohoku University moved down to 165th from 150th.
