Nagano's Saku Chosei fought back from a six-run deficit to beat Higashiyama of Kyoto 11-7 in the national high school baseball championship Tuesday.
After cutting Higashiyama's lead to 7-6, Saku Chosei went ahead for good in a five-run eighth on a two-run single by Daisuke Harano before Yoshimasa Ogihara capped the scoring with a two-run homer.
In Tuesday's other second-round games, Yugakukan of Ishikawa Prefecture routed Gunma's Kiryu Shogyo 8-3 in a meeting between Koshien debutantes, Chukyo of Gifu Prefecture beat Oita's Yanagigaura 5-3, and Koryo of Hiroshima beat Yamanashi's Japan Aviation 3-2.
Yugakukan built a 7-2 lead through six innings after Atsushi Gyoda hit the 1,000th homer in the history of the annual tournament while left hander Tatsuya Kojima struck out 15 over the distance.
Ryo Sakakibara pitched a complete game as Chukyo won for the first time in 27 years.
