Chiefs of local governments in central Japan on Monday condemned the organizer of a hip-hop music event held the previous day in Aichi Prefecture for its lax COVID-19 measures despite a pledge to follow the anti-infection guidelines set by the live concert industry.

According to the Aichi prefectural government, about 8,000 tickets had been sold for the event, Namimonogatari2021, held at a convention center in Tokoname, which its organizer says is one of the largest outdoor music events in Japan, bringing together hip-hop and R&B artists.

"No social distancing was observed near the stage, and some alcoholic beverages were sold at the venue. It is extremely regrettable that our safety requests were not followed," Aichi Gov. Hideaki Omura said in a press conference.
