Hi there,
I was wondering if anyone here had walked the entire Tokai Nature Trail. I'm interested in doing this walk in Spring next year but I wanted some advice from anyone who'd done it already as there isn't a lot of information online.
I am thinking of buying a map (the Yama-to-Kogen-chizu) to aid me, and I can speak/read a fair amount of Japanese.

My questions are these:
1. Is the route well sign-posted?
2. Are there safe and inexpensive places to stay along the way? Camp-sites?
3. Just how difficult is the trail?
4. Would it be inadvisable to walk it alone?

Any other information or advice would be greatly appreciated.
Thank you!
