In 1901, Keio University played "Yokohama Foreigners" losing 35–5, but the game demonstrated that the racial barriers in the sport were breaking down. Prof. Clarke played in this game, taking the conversion, after a student called Shiyoda scored a try. From Keio, Japanese rugby swept to the other universities of Japan, and to this day, the private universities remain a stronghold of the Japanese game. Doshisha and Waseda played their first inter-university game in 1923. The Keio and Waseda match, a long running rivalry between two of Tokyo's most prominent universities, has been played annually since 1924.
