The translation was rough to understand so hopefully I did the scores correctly. I tried watching this event live but my feed was really choppy and then I couldn't refresh the link. I got tired so I went to sleep. The Japanese Universiade team for 2013 will be Ryohei Kato, Yusuke Tanaka, Shogo Nonomura, Chihiro Yoshioga and Hiroki Ishikawa. I'm not sure if I got all the names right.
Oh I just found Day 2 part 1 (watch it before it might get deleted)
