The soccer J-League will be held safely in the match between J1 Nagoya Grampus and FC Tokyo on April 3 in Toyota City, Aichi Prefecture, with 20,000 spectators who exceed the standards of the government guidelines. I decided to investigate whether I could do it.

The soccer J-League is currently holding a match with an upper limit of 10,000 spectators in accordance with government guidelines as a countermeasure against infection with the new coronavirus.



The J-League will play J1's Nagoya Grampus and FC Tokyo on April 3 at Toyota Stadium in Aichi Prefecture in an attempt to provide useful data for running large-scale sporting events such as the Tokyo Olympics and Paralympics. So I decided to do a special investigation.



With the permission of the local government related to the national government, the maximum number of spectators will be raised to 20,000 only for this match, and it will be used as a guide to judge the risk of infection in cooperation with the National Research and Development Corporation and the National Institute of Advanced Industrial Science and Technology. In addition to measuring the concentration of carbon dioxide and the wearing rate of masks, NTT DoCoMo's mobile phone radio waves are used to analyze the behavior of spectators.



The J.League will provide data to the national and local governments as soon as the results of the survey are finalized.
