The daily number of new coronavirus cases reported in Japan on Friday topped 100 for the first time since May 9, adding to signs that the epidemic is gaining strength since the country eased business and social restrictions.

Of the 105 cases, Tokyo reported 54 — 31 of them connected to the nightlife industry, such as at so-called host clubs, where women pay to drink with and be entertained by young men. The daily figure for the capital came to around 50 for the third day in a row.

Since Japan lifted a nationwide state of emergency entirely on May 25, it recorded more than 70 new COVID-19 cases for six days and the cumulative number reported each week has been increasing gradually. It was 291 two weeks ago, 407 last week, and has reached more than 500 this week.
