J-League and NTT Group, the official technology partner of J-League, as well as the National Institute of Advanced Industrial Science and Technology, will collaborate to conduct a survey to confirm the effectiveness of infection prevention measures at the 2021 Meiji Yasuda J1 League Matchday 9 between FC Tokyo and Kawasaki Frontale (14:00 kickoff / Ajinomoto Stadium).
In accordance with this, we will raise the upper limit of the number of visitors during the survey from now on.
