I live in Tokyo, Japan isn't 'doing well'. It has gambled on its citizens' and residents' health by not testing because it didn't want to have any problems before the Toky Olympics.
We had the first wave of the Wuhan Virus as it was known then back in January when business people came back to Japan from Wuhan and when the usual business was taking place with many Chinese people entering for business as well as a massive amount of tourists and lesser amounts of international students.
To be fair there was a general taking of precautions - hand sanitizer made available in many stores, put in restrooms where there was none previously, many people serving the public wore masks because the Japanese are used to wearing them to go sick to work and in the hay fever season, some companies went to remote work in February, some businesses including tourist attractions were cloed, schools were closed.
Unfortunately all the school closing did was result in high school and other teenaged students hanging out in popular areas making more crowds. Primary school students didn't ride the trains but they played close outdoors. I think some virus transmissions have come through those activities from asymptomatic cases but as people continue to be turned away as adults from clinics and won't be tested, testing young people and children is the last thing Japan is going to do. Then here in Tokyo a lot of people decided the emergency was over in March. They packed the trains again including outside rush hour and old people rode around too.
Since the Olympics delay was announced - surprise, surprise there are many more cases popping up. And the numbers still don't reflect the plausible reality as Japan refuses to test on any real scale for a population of 125 million. You can't find out where cases are unlike in the UK and other countries through simple online trackers. Only bits of information are being released here and there. Japan is also probably the most secretive developed country in the medical field as well as some others. Autopsies are not done as a rule and you can bet that there are deaths due to COVID-19 not being listed because of some other condition present.
Oh and I knew the figures for some other cities was laughable. I used to live in the biggest city down south-west and that is very popular with tourists and Japanese visitors. Until recently it was showing 5 cases - nonsense - and now there are more but testing would reveal the real scale. It was also reported in the news recently that authorities cannot track a fair number of cases - when you have secrecy and don't test and then isolate as a matter of course, guess what?
