I had never felt so safe while I was there. I knew I didn't have to check over my shoulder, or walk down a side road if I wanted to use my phone so as to avoid having it grabbed from my hands. When I rented a bike, I could simply park it up without a lock, and knew I would come back to see it exactly where I left it. I forgot my bag in a taxi and got it back the next morning by going to the taxi office. I left my umbrella on a chair and came back to see it exactly where I left it.

It's how living in a civilised, first world country should be.

Japan is absurdly safe and law-abiding, even by developed country standards.

They're 12th on this list: https://en.wikipedia.org/wiki/List_of_countries_by_intention...

The top 10 are mostly microstates or Pacific Island nations.

Answering your comment seriously, with an appropriate level of flippancy:

On the Tokyo metro this year I saw many advertisements for hair issues; lots of ads with balding noggins, contrasted with thick gorgeous heads of hair that you can acquire by making an appointment through a (naturally!) Japanese domain. In London, meanwhile, I saw zero ads for any hair-related products or services on the tube. Though if there were, I would imagine most would be advertised with a UK TLD.
