Baseball and softball will return to the Olympics in 2020, while skateboarding, surfing, karate and sport climbing are joining the Games for the first time.

The IOC on Wednesday approved the addition of those sports to the Tokyo Games, calling it an "innovative mix" of traditional and youth-oriented events that will attract Japanese and global fans.

The five bids, including a combined baseball-softball pitch, were put forward for inclusion last year by Tokyo organizers.
