The Japanese squirrel is a small rodent that lives in trees in the forests of Japan. It is active during the day, climbs well, and feeds mainly on seeds and nuts.
The Japanese squirrel is smaller than the common squirrel and has a shorter tail. It is important for the forest because it disperses tree seeds and helps them spread.
