Japan has an even more elderly population than Italy, yet a lower CFR than South Korea. Is Japan testing enough? Are they somehow self-isolating way better than anyone else?
Japan isn't really doing much and many suspect that they are deliberately looking away from the coronavirus outbreak because of the 2020 Olympics later this year. IMO, the gov't willful neglect and concealment is exactly what enabled the coronavirus outbreak in Wuhan, China and I fear this might come back to bite them later.
