In total 2,487 people have died of the coronavirus in Japan, just over half the number in China and fewer people than on a single day in America several times over the past week. Japan has suffered just 18 deaths per million people, a higher rate than in China, but by far the lowest in the G7. As early as March, Japanese officials began warning citizens to avoid the san-mitsu or "3Cs": closed spaces, crowded places and close-contact settings. The phrase was blasted across traditional and social media. Authorities [made] granular distinctions about risks, opting for targeted restrictions rather than swinging between the extremes of strict lockdowns and free-for-all openings. Nishimura Yasutoshi, the minister overseeing the government's response to covid-19, carries a device that monitors carbon dioxide to measure the quality of ventilation during his meetings. Crowded subways pose little risk, if windows are open and passengers wear masks, Mr Nishimura insists. Sitting diagonally, rather than directly across from each other can reduce the risk of infection by 75%. Movie theatres are safe ... Mr Nishimura says. While most cinemas in the West are closed, "Demon Slayer", a new animeflick, has been playing to full houses in Japan. In addition to the 3Cs, the Japanese government warns of five more specific dangers: dinner parties with booze; drinking and eating in groups of more than four; talking without masks at close quarters; living in dormitories and other small shared spaces; and using changing or break rooms.
