Operators of nightlife establishments will have to keep a record of their customers' names and contact information and enforce social distancing rules as part of measures to contain the spread of the coronavirus, according to guidelines released by the government on Saturday.

The guidelines on nighttime establishments, including host clubs where women pay to talk to male employees over drinks and snacks, come as new infections in Tokyo are being traced to such businesses. The new rules were also made public before nightclubs and similar entertainment establishments reopen from June 19.

Economy minister Yasutoshi Nishimura urged the businesses to reopen by taking proper countermeasures against COVID-19. "It's an effort to protect the lives of employees and customers," he told a news conference.
