Hello everyone,
I'm planning to go out for a few days during the summer vacation to practice my survival skills (they've gotten a little rusty since I came to Japan). I know I am capable of handling myself back in my home country (South Africa), but I'm a little unsure of the Japanese flora etc, so this is going to be a test run for me.

I was wondering if anyone had any advice on books of edible Japanese plants? Also, am I correct in the assumption that you can't hunt anything here without a permit? Even small game? What about fishing?

Thank you very much for your help!
