What animals are native to Japan?

Lots! There are many species of animals native to Japan. Some of the ones that first come to mind are the snow monkeys, which are a type of macaque. There are other native mammals such as bears, deer, otters and minks, and small mammals like shrews, moles, mice etc... There are tons of native birds, too. Japan, being an island, has lots of water-related birds: herons, egrets, cranes, ducks, and the like. Also there are native turtles and fish, and of course insects and other invertebrates.

Pikas live there and so do dugongs and some 50 species of bats.
