Mating behaviors are not well known for this species, but they are thought to be strictly monogamous, breeding and nesting with only one other mate. Extending down from the ears on the side of the face are white bands of fur. The face is almost raccoon-like in color, with black bands around the eyes. The skull is broad with distinct post-orbital processes and a short rostrum. Japanese giant flying squirrels are the largest members of the family Sciuridae, weighing up to 1.3 kg. There are nine carpal bones in the wrist of this species, which has a special, long accessory styliform cartilage that supports the flying membrane while gliding. Flying squirrels generally have longer limbs than non-gliding squirrels. A fur-covered membrane extends from the side of their body from the wrists to the ankles, which allows these squirrels to glide between trees. The ventral surface is yellow, buff, brown or white. The tail is usually longer than the body and is the color of the fur on the back. This species has long, soft fur ranging in color on its back from yellow-gray, brown, chestnut and black. There are six species of giant flying squirrels, including the largest, Petaurista leucogenys. ( Ando and Shiraishi, 1993 Kawamichi, 1997a Kawamichi, 1997b Kawamichi, 1998 Nowak, 1997) They often inhabit forested areas around shrines and temples. Forests include tropical and temperate with a mixture of tree species, such as deciduous and coniferous trees. This species inhabits areas of forests, hills and mountains. ( Ando and Shiraishi, 1993 Kawamichi, 1997a Kawamichi, 1997b Kawamichi, 1998 Stafford, et al., 2003) Many studies of this species have been carried out in Nara City, located in central Japan. As a matter of fact, when creating gliding suits, humans have tried to imitate flying squirrels.Japanese giant flying squirrels are found in southern parts of Asia and Japan, including the islands of Honshu, Kyushu and Shikoku in Japan.When landing on a tree, they scurry around to the other side of the tree in order to get rid of predators that may have followed them during gliding. The flying squirrels are extremely cautious animals.When the squirrel lands on a tree, the fluffy tail helps the animal balance, acting as an air brake.The flying squirrels are thought to have originated about 18-20 million years ago.

Then, at 1 week old, their skin darkens and fur begins to emerge on it.

Internal organs of newborn squirrels are usually visible through the skin. Babies of this species are born with closed eyes and no fur.It acts as camouflage, allowing the squirrel to merge with tree bark, due to which the animal looks like a bump on the bark, confusing predators. The specific coloration helps this animal remain unspotted as it sits on a tree.In this position, they stretch their bodies and reach out to whichever item is accessible, instead of moving around to find food. Japanese dwarf flying squirrels eat in an unusual way, usually hanging upside down a twig or branch when chewing their meal.In addition, newborn young are known to share the nests with their mothers, suggesting that mothers and their offspring use certain types of tactile communication. Nothing is known about the communication habits and behavior of this species, although these animals are believed to use vocalizations, including chattering sounds. However, they are known to occasionally sleep for several days at a time during the winter months. Japanese flying squirrels do not hibernate and are active throughout the year. Several individuals of the same sex can share the same tree, except for the mating season, during which they gather in mixed groups. Japanese flying squirrels are mainly arboreal, rarely descending to the ground. These rodents are silent gliders and move quickly among the tops of trees in order to escape potential predators.

Japanese flying squirrels are strictly nocturnal creatures that spend their daytime hours in their nests or in tree holes, coming out of their shelters only at dusk.
