J.LEAGUE announced the start of polymerase chain reaction (PCR) testing on all registered players in the league, officials, etc., prior to the resume/start of the MEIJI YASUDA J1 LEAGUE, MEIJI YASUDA J2 LEAGUE and MEIJI YASUDA J3 LEAGUE, using saliva.

The PCR testing will be done as one measure to reduce the risk of infection as much as possible on the pitch, given the competitive nature of football which involves physical contact. The J.LEAGUE will establish a testing center managed by the league and a specialized organization will do the testing about every two weeks until the end of the season in December. Only those who are tested negative in the most recent PCR test designated by the league will be eligible for entry to the matches.
