Habituated but free-ranging monkeys being studied by Kyoto University.
A herd of Japanese macaque scrambled about on the hillside. We saw about 25, including many babies, from the window of the bus, but the driver wouldn't let us get out of the bus because they can be aggressive with people (who have fed them).
Japanese macaque "monkey"
Spotted on the side of the road in the Shimokita Peninsula, Aomori Prefecture, Japan. These "Japanese snow monkeys" as they are often called are the most northern non-human primates found on Earth. They are not found to the north in Hokkaido but they are endemic and wild north all the way up to the the Shimokita peninsula at the top of Honshu, the main island of Japan, where they spend harsh freezing winters in bare trees, a remarkable feat of survival.
A troop seen.
Seen in the Jigokudani Forest Reserve.
Saw three of them grazing on long grasses about a quarter way up the mountain
The Japanese macaque (/məˈkɑːk/;Macaca fuscata), is a terrestrial Old World monkey species native to Japan. It is also sometimes known as the snow monkey because it lives in areas where snow covers the ground for months each year — no primate, with the exception of humans, is more northern-living, nor lives in a colder climate. Individuals have brown-grey fur, red faces, and short tails. There are two subspecies.
