I live in Tokyo and well, I'm not so sure. Maybe you just got lucky or I got unlucky. I've lived in places where they neighboring couple would scream and throw things at 3-4am for 30 minutes every couple of weeks. Lived in a place across the kanda river from the Chou line where the trains were so loud I couldn't hear the TV when they went by. My current place is nice enough but I feel I have to tiptoe all the time which I hate. I want to not have to think about it rather then always have to think about it.

Those are not unique to Japan though. My SF apartment had the thinest floors ever and I got all kinds of complaints even though I'm way more aware of the noise I make than most, even going so far as to always watch TV with wireless headphones.

Conversely I've lived in apartments designed for noise in Los Angeles where the landlord told me it was okay to run the washing machine 24/7 because the neighbors wouldn't be able to hear it next door as the walls were concrete and doubled with a space between to absorb the sound.

I know some of the newer 20-30 floor apartment buildings in Japan are built similarly but I don't currently make enough to live in a place like that, probably $3k-$4k a month for a 2LDK

Not being able to walk across your own home at night is reason 1 of 100 why I choose suburban sprawl over high density. It's like a damned prison.
