When I lived in Japan, I practiced archery just because I wanted to keep my eye in so I could hunt elsewhere.

I never came across any restrictions.

I didn't want to run afoul of the law, so I made sure to ask. The desk sergeant at the local cop shop was somewhat amused I even brought the question up.

How can possession of a bow be illegal when you can make one yourself out of wood?

It was clear to me after getting laughed out of the Japanese police station I could do whatever I wanted with my bow.

As long as that didn't include hunting, which was clearly illegal.
