Mount Kawayama (妙川山, Myōkawayama, literally Mysterious/Exquisite River Mountain) is the land of Monkeys, the place where all the monkeys that Jubei summons live. It is home for huge and small Monkeys and apes alike. Mount Kawayama is a rich and beautiful land. For a human to get to Mount Kawayama, if they have a summoning contract, they can let a monkey use the Reverse Summoning Technique. Jubei was transported to Mount Kawayama in his youth via using the summoning technique without a contract.
