The Asian Games are open with more athletes than the Summer Olympics and some unfamiliar sports

The opening ceremony of the Asian Games has marked the official start of the 16-day event

NAGOYA, Japan -- The opening ceremony of the Asian Games on Saturday marked the official start of the 16-day event — but in name only.

Facing a packed schedule, competition in basketball started on Sept. 10 — more than a week ago. The semifinals in men's basketball were on Friday, a day before the official opening.

Soccer has been going on for almost as long. The Summer Olympics typically start a few days early, but this multi-sport event pushes the envelope.

Welcome to the Asian Games , which feature at least 11,000 athletes. The 2024 Summer Olympics in Paris had about 10,700. The last Asian Games in Hangzhou, China, in 2023 had roughly 12,000.

Japanese organizers have yet to release an official athlete total from the 45 countries and regions contesting 43 sports. But it seems likely to reach the total in China of three years ago. Maybe more with a few new sports added.

The games feature the old-standby Olympic disciplines like track and field, swimming and soccer. But there are some Asian specialties, too: kurash, kabaddi, and sepaktakraw to name three.

Kurash is an ancient form of wrestling that originated in Uzbekistan. Kabaddi looks like a game of team tag with a physical edge. And sepaktakraw is a mix of volleyball and soccer.

Games organizers have also added mixed martial arts, padel and teqball to the menu — with esports also on the schedule — hence the time crunch.

Host Japan has the largest delegation with 933 athletes and China came with just over 800. China won 201 gold medals in the last games, followed by Japan (52) and South Korea (42). That pattern is expected to be repeated.

Emperor Naruhito and Empress Masako headed the list of dignitaries. The president of the Olympic Council of Asia, Sheikh Joaan bin Hamad Al Thani, elected earlier this year, was alongside.

“Tonight the eyes of Asia, and much of the world, turn to Japan,” Sheikh Joaan said in his address, which was followed by the Emperor officially opening the games.

The president of the International Olympic Committee, Kirsty Coventry, was also present.

The theme of the opening ceremony was the “Harmonic Heart Beat,” and the stage on the infield at the Nagoya City Stadium was in the shape of a large heart.
