For a country obsessed with rules, regulations and infuriatingly convoluted ways of doing unimportant things, Japan is oddly lax when it comes to the likes of food hygiene. Small eateries that’d be shutdown in a heartbeat in other regions, or old places with cooking appliances that haven’t experienced a good scrub in decades, are oddly commonplace. In fact they thrive, with the grime arguably adding to the gourmet experience.
And the same goes for slightly larger concerns. The clutter, cramped conditions and relative uncleanliness are just accepted. Or if not accepted, then at least ignored.
