Japan is filled with cute critters, but these pint-sized squirrels are at the top of the list. The Japanese dwarf flying squirrel and Siberian flying squirrel are known for their big eyes, small stature, and overall adorable appearance. In fact, they’re so popular in Japan that they’re even used as the design on Sapporo’s metro card.
The Japanese dwarf flying squirrel (Pteromys momonga) is only found on Japan’s Honshu and Kyushu islands. Living in sub-alpine forests and boreal evergreen forests, these nocturnal animals blend into the trees with their coloring. With their body measuring up to 20 centimeters and their tail growing up to 14 centimeters, their small size can make them hard to spot.

Though the name might confuse you, these squirrels don’t fly. Instead, they use a membrane called the patagium to glide from tree to tree. Feasting on seeds, fruit, tree leaves, buds, and bark, these squirrels forage at night and spend their days tucked into the holes of trees. These rodents only mate once or twice a year, but their population is abundant and the IUCN has it listed as an animal of “Least Concern.”
