Yeah, this post sounds fake and wrong and should be rejected. Japan is most likely the most hygienic country on earth (okay, Singapore may beat them). Sure you can find some backwater somewhere in Japan with worse hygiene than the USA, but the overwhelming majority of that nation has levels of hygiene which make even the cleanest parts of America look like a pig pen.
Are you serious about Singapore being hygienic? Ever been to hawker stands in Singapore? Ever visit Little India on a Sunday? Ever walk though the food section of Mustafas? Especially the eggs isle? And yes I know they are inspected.
