One more location marked on the map (from the H-shop) I don't seem to remember. Again it's most likely from Onegai Teachers, which I haven't seen.

But at least it's a nice picture. Amazing how the creators made a 1:1 copy of Kizaki for the animes. Every single tree you see in the anime, they are all here for real!

Ow yeah, a walk around Kizaki lake is about 12km. The most interesting areas are Camp Side, H-Shop, and around the hostels area (which includes the Yupuru complex ^_^).
