Mount Myōboku

Myobokuzan is the land of toads, the place where all the frogs that Naruto, Minato or Jiraiya have summoned, live. It is home for huge and small toads alike. For a human to get to Myobokuzan, its either take a month long travel from Konohagakure or let a toad use Reverse Summoning Technique.

Myobokuzan is a rich and beautiful land, whose ultimate authority seems to be the Toad Sage. Shima and Fukasaku are both elders and sages, and they seem to have an even higher authority than Gamabunta himself. There are many statues of the frog ancestors and people trying to learn Senjutsu, but failing and becoming statues. The statues are treated with a lot of respect.

Some of the inhabitants of Myobokuzan can use Senjutsu, to gather natural energy. There's a sacred fountain in Myobokuzan where a special oil makes it easier for people to feel the natural energy, but if the person is not perfectly still and becomes one with nature, he or she starts becoming a toad and eventually into stone.

The List
Myobokuzan has records of its population in a list, and the name of a Myobokuzan toad stays there until it dies.
