We drive on the left in Japan and used to carry swords (at least some of us, not everyone).

I have one of your swords.
My Dad bought it for me in the 1980’s.
Also a Daruma doll yet to receive both eyes.
you have to make a wish to receive them other wise they don't turn up 😆
Haha!
Daruma scared me when I was a kid 🤣
Yes you don't want to clash katanas and being an island too means it's easier to keep out all the people who are doing it wrong 😁
