Substitute Takuma Asano struck twice in the second half as Japan came back from two goals down to beat archrival South Korea 3-2 to win the Asian Under-23 Championship on Saturday.

It looked gloomy for Japan after Kwon Chang-hoon opened the scoring in the 20th minute for South Korea before Jin Seong-uk doubled the lead two minutes into the second half.

But Asano, who took the pitch on the hour for Ryota Oshima, closed the gap in the 67th minute with his first of the evening from a through pass by Shinya Yajima.
