Koketsugakure (虎のデンdに隠された村; Koketsugakure no Sato; literally meaning "Village hidden in the Tiger's Den) is a sacred place of the land of tigers, the place where all the tigers that Poji and Kajin have summoned live. It is home for huge and small tigers alike. Koketsugakure is a rich and beautiful land, whose ultimate authority seems to be the Great Tiger Sage. Hiroin and Tsukuyominomikoto are both elders and sages, and they seem to have an even higher authority than Toramikiri himself.
For a human to get to Koketsugakure, it either takes a year long travel on secret paths from Amegakure or, if they have a summoning contract, they can let a toad use the Reverse Summoning Technique. According to Tsukuyominomikoto, Koketsugakure is impossible to find by foot for those who don't know the secret route.
There is a special portal called the Underground Transportation Route (地下の輸送ルート, chikanoyusouru_to) that links Koketsugakure to the world, that enables the smaller tigers to quickly travel between the places without the use of the summoning technique. On Koketsugakure exists a score of horrific genjutsu that have passed down since an immemorial time. Of which is a genjutsu that only the two great sage tigers have mastered such as the Demonic Illusion: Tiger Nightmare Technique. These genjutsu are very powerful and can only be performed by combining the roar and the glare that the tigers can do.
Some of the inhabitants of Koketsugakure can use senjutsu, to gather natural energy. There is a sacred fountain on Mount Koketsugakure which produces a special tiger balm which allows people to more easily feel the natural energy around them, it also helps relieves pain, but if the person is not perfectly still, becoming one with nature, he or she starts becoming a tiger and eventually turns into stone. This balm can only exist in the atmosphere of the mountain, and will evaporate if taken outside, without being in pill form. There are many statues of the frog ancestors and of people who tried to learn senjutsu, but failed and became toad statues. The statues are treated with much respect.
Most inhabitants of the village can preform Kekkei Genkai, Kekkei Tota and Hiden Techniques. Being one of there specialities. The village was founded by the Great Tiger Sage, Yogensha.
