Foreign athletes competing at this summer's Tokyo Olympics and Paralympics could be kicked out of Japan if they violate regulations aimed at preventing the spread of coronavirus infections, according to a rulebook released Tuesday.

The third and the newest version of the "playbook" with various COVID-19 countermeasures also said all athletes may face penalties for not complying with them, including a withdrawal of accreditation and the right to participate in the games, as well as facing a fine.

"There may be consequences imposed upon you in the event of a breach of these measures...including procedures for revocation of your permit of stay in Japan," it said, while noting that some of the steps are under the jurisdiction of Japanese authorities.
