And one of the points that's a little more obvious living here: Japan is a remarkably car centric culture. Not quite to the extent of America, but in much of the country you really do need a car.
If anything the main exceptions to that are exactly the places tourists are most likely to go.
I disagree, I lived a year in a small town near Osaka far from any tourist attractions and never did I wish I had a car. Public transport was ubiquitous and walking infrastructure excellent. Lots of people on bikes. Roads were tiny so cars on them are tiny and driving slowly, making it feel safe to share the roads with them.
Maybe the most clear indication that Japan isn't a car centric culture was the complete lack of FREE parking space.
