The name Yakuzaru means the monkeys of Yakushima . Yakuzaru are different from other Japanese monkeys. They have a stockier body and darker hair. Habitats of monkey are extended from the sea side to near the top of mountain. The forest in lower altitude has broadleaf trees.
Monkey lives in the forest and usualy moves by walking on ground with four legs.
Sometimes they are climbing on the tree and jumping to the other tree. Although highest mountain in Yakushima is about 1900 meters sea level.there are some monkeys near the top. But I don't know more how they are living. I only seeing them for once. A view of Yakushima coast.
