Habitat
This species primarily inhabits temperate broadleaf and mixed forests in Japan, including mountainous regions with old-growth trees. They prefer areas with dense canopies for gliding and nesting in tree hollows, ranging from lowlands to elevations up to 2,000 meters. Geographic distribution is limited to the islands of Honshu, Shikoku, and Kyushu.
Diet
The Japanese giant flying squirrel feeds mainly on nuts, seeds, and fruits from trees like oaks and beeches, supplemented by leaves, buds, and occasionally insects. They forage nocturnally, using their gliding ability to move efficiently between food sources. Feeding behavior includes caching food for later use during scarce periods.
Behavior
These squirrels are primarily nocturnal and arboreal, spending most of their time in trees and gliding to escape ground predators or reach food. They are solitary animals except during mating season, maintaining small territories in their forest habitats and communicating with vocalizations or scent marking. Notable behaviors include folding their patagium for climbing and using nests in tree cavities for shelter.
Conservation Status
The IUCN status is Least Concern, with a stable population trend, though habitat loss from deforestation and urbanization poses a threat in parts of Japan.
