For Yuuki Hamazono, it was a relief to find bars and restaurants in Tokyo flouting the Japanese government's request to close by 8 p.m.

The 30-year-old financial trader was one of many people out in the Shimbashi nightlife district during the first weekend of an expanded state of emergency, with the government pleading for residents to stay home to contain the coronavirus.

Prime Minister Yoshihide Suga declared a state of emergency for Tokyo and surrounding prefectures this month. He expanded it to 11 prefectures accounting for 55% of the population on Wednesday. Unlike in many other countries with mandatory lockdowns, Japanese authorities legally can only urge people to stay at home and businesses to close.
