What you are about to see is a match point situation and final points of play from a televised match in Japan. There are 8,000 fans watching this game and it's the Championship of this league. The announcer is Mr. Matsuidiara, the 1972 Gold Medal coach of the Japanese Men's Olympic Team. The blue team is serving for match and championship point after winning the first set and being up 14-10 in this game. Watch for amazing match point saving digs in the lower right hand corner by the red defender and the way way they set outside even though they are running/faking the middle quick sets.
About 2:30 into the video there will be further explanation about what you are watching. Prepare to have your mind blown :)
