Found these guys in Nagano Japan when I lived there a while back!
I saw a monkey jumping from trees to trees. no photos.
Seen in the first driveway on the right after getting on the road to the Nikko Kirifuri Ice Arena from the Rte. 169/Marumi intersection. The location is just northwest of the Hotel Casual Euro.
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).
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.
