University of Nebraska standout Keisei Tominaga made six three-pointers and scored a game-high 20 points as Japan defeated Angola 75-65 Tuesday in a FIBA Basketball World Cup warmup game.

Japan, ranked 36th in the world, turned a 49-44 deficit into a 51-49 lead at the end of the third quarter and never looked back against No. 41 Angola at Tokyo's Ariake Arena.

Tominaga shot six of 14 from three-point range. Chiba Jets point guard Yuki Togashi added 13 points for head coach Tom Hovasse's team.

An injury concern popped up for Japan as the Phoenix Suns' Yuta Watanabe did not return after hurting his right ankle in the second quarter.

Japan will also play warmup games against France on Thursday and Slovenia on Saturday before taking on 11th-ranked Germany on Aug. 25, the opening day of the World Cup, to be co-hosted by the Philippines, Japan and Indonesia.

Japan has also been drawn with No. 24 Finland and No. 3 Australia in a challenging Group E at Okinawa Arena. The top two teams in each group advance to the second round.
