The 2017 Asian Championship was held in October 2017 in New Taipei City. The participants were the top four finishers from the 2015 Asian Championship ( Japan, South Korea, Chinese Taipei and People's Republic of China), the top two teams from the 2017 West Asian Cup ( Sri Lanka and Pakistan) and (as there was no East Asian Baseball Cup this year) the two highest-ranked teams that play in the East Asian Cup ( Philippines and Hong Kong. China was a late withdrawal, citing administrative issues and trouble booking return tickets due to the Golden Holiday in that country, denying politics played a role in not going to Taiwan (they had attended the 2012 and 2015 Asian Championships in Taiwan).
- Japan 30, Hong Kong 0. Japan starts with an expected 4 1/2 inning mercy rule romp. Hong Kong starter Chung-Hei Leung retires none of the nine batters he faces, with 3 walks, four hits, a hit batsmen, an error and 8 runs (6 earned) while Masaki Tanigawa strikes out five in three perfect innings before LF Ho-Lam Andy Lo singles off Keita Hirao in the 4th for the first Hong Kong baserunner. 3B Hoi-Ting Cheng adds a triple off Keita Watanabe in the 5th. 2B Shunta Tanaka has 4 runs and 5 RBI, backup RF Kazuki Kanizawo drives in five and homers and C Yuki Yamauchi drives in five and scores three, going 5-for-5.
