J.LEAGUE and NTT Group, the official technology partner of J.LEAGUE, as well as the National Institute of Advanced Industrial Science and Technology, have collaborated to conduct a survey to confirm the effectiveness of infection control measures at the 2021 Meiji Yasuda J1 League Sec. 9 match between FC Tokyo and Kawasaki Frontale (kickoff at 2:00 PM / Ajinomoto Stadium).
In accordance with this, we will raise the upper limit of the number of visitors during the survey.
