Each National Olympic Committee can enter a maximum 18 competitors (12 men and 6 women), with a maximum of one athlete per event. As hosts, Japan will be given two quotas (1 man and 1 woman) to compete, if they fail to qualify normally. This will cause a reduction of quotas given at the Asian Qualification Tournament. The remaining quotas will be decided through various events, specifically, the 2019 World Championships, the Continental Qualification Tournaments and the 2021 World Qualification Tournament.
Qualification events are listed in hierarchical order.
