TOKYO — Baseball and softball were joined by youth-oriented sports such as surfing and skateboarding as Japanese organizers on Monday recommended the inclusion of five additional sports and 18 events for the 2020 Tokyo Olympics.

Karate and sports climbing were also on the list proposed by the Tokyo organizing committee. Bowling, squash and wushu failed to make the cut from the list of eight finalists.

The recommendation will be submitted to the International Olympic Committee, which will make a final decision in Rio de Janeiro in August 2016.

Under the “Olympic Agenda 2020” program adopted by the IOC last December, host cities are allowed to propose one or more additional sports for their games.

The proposed new events would add 474 athletes to the Tokyo Games, a total that fits within the cap of 500 additional athletes set by the IOC.

The IOC has repeatedly stressed that any additional sports must have a strong youth appeal, something which Tokyo organizers sought to address.

“This package of events represents both traditional and emerging, youth-focused events, all of which are popular both in Japan and internationally,” the organizing committee said in a statement.
