Shun Takayama homered and drove in five runs, Kentaro Yoshinaga threw a shutout and Tokyo's Nichidai Daisan routed Kosei Gakuin of Aomori Prefecture 11-0 in the final of the National High School Baseball Championship Saturday.

The Nihon University affiliate school finished at the top of 4,014 participating teams across the country from the regional preliminaries, winning the summer tournament for the first time in 10 years and the second time overall.

Takayama, batting fifth and playing right field, gave the Tokyo school a 3-0 lead in the third inning with a three-run shot over the center-field wall at Koshien Stadium.
