Well I mean, it's a totally different viewpoint visiting vs living. I would say yea, the cleanliness and safety are hard to argue with and huge perks for me. I can go out jogging at midnight with headphones on and zero situational awareness and the worst thing that will happen is that I'll accidentally scare someone I come upon.
But there's a lot of negatives that you see when you live here a while (in Tokyo). People are generally cold and indifferent. If someone falls crossing the street, rarely will anyone help. My fear of being mugged has been replaced by the fear of having a heart attack and convulsing on the ground while no one helps or a few look on confused as to what to do while I waste away. There is rampant racism, which unlike the general vibe in north america, is completely overt. You want to live here? Sorry, no foreigners. And show up every weekend to the embassies of other asian countries to see convoys of people shouting ~"Koreans go home" out of loudspeakers, with police officers escorting them. Throw any notion of local community out the door. Neighbors typically work to avoid contact with each other. No "hey, we're having a BBQ - come on over!" In the work setting everything is far worse. Many people are worked to exhaustion. A contract might specify a typical 50 hour a week job, but require 30 hours of unpaid overtime "built-in". This quite typical. But the quality of the work doesn't matter as much as the appearance of the work, so you should just basically sit at your desk and dick around until your boss leaves. It's moving the whole economy into oblivion.
Don't get me wrong, I do enjoy living here, and really, really enjoy kansai area (which I hope to move to at some point), so there's more pros than cons in my mind. But there's a hell of a lot of cons and romanticism of Japan in the west. For most of my friends that I met here or moved here, they're not here anymore.
But it is clean
