The interesting thing about Japan is that they did not institute lockdowns unlike many of the Asian countries, instead relying on the good sense of the Japanese rather like the Swedes. They did started having quasi lockdowns though as cases mount. They did alot better than the Americans with 87.47 deaths per million, this compared with the USA at 1,767.87 per million. That is literally 20x better tha the USA.
Part of the reason despite their beginning lack of lockdowns is that in Japan (and most Asian countries) there is no confusion about whether the disease is real or fake, or the wearing of facemask. There are some kooks here and there, but for the most part. The Japanese took it seriously.
