Any forest could be suitable for my work. A large and rich forest is good. I think a forest, that has less undergrowth and is easy to walk, is good.
In Japan, there is a good forest at Karuizawa. It is a summer resort where you can take a day trip from Tokyo. Karuizawa is a summer resort, but winter is also wonderful.
Of course, I think the Argentine forest is also wonderful.
In the forest, there are many voids of a suitable size. Therefore, I will prepare a work suitable for that size.
