After a record-setting 2019 season that saw larger crowds than ever attending games from Hokkaido to Okinawa, the J. League is committed to keeping both its fans and players safe.

Following a similar request to reporters covering last weekend's Super Cup at Saitama Stadium, media attending Friday's J. League Kickoff Conference were urged to wear masks as they spoke to players and managers about the upcoming first-division season.

"We've shared the package we used at last week's Super Cup with all of our clubs," J. League Chairman Mitsuru Murai told The Japan Times.
