- Japanese name
- ハタネズミ
- Group
- Land mammals

It lives on Honshu, Kyushu and other parts of Japan, in places such as the edges of fields and rice paddies, riverbanks and woods.
It digs a web of tunnels underground. Its ears are small and its tail is short, so they do not get in the way as it moves through the tunnels.
Its Japanese name is said to come from the way it turns up in fields and rice paddies. It eats plants such as grasses and daisy-family plants.
