Japanese deer, known as sika deer, are native to Japan and are characterized by their spotted coats, which help them blend into their forested habitats. They are medium-sized animals, with males typically larger than females. These deer are herbivores, primarily feeding on grasses, leaves, and fruits. Sika deer are social animals, often found in groups called herds. They are known for their vocalizations, which include barks and whistles. In Japan, they are considered a symbol of nature and are often associated with the sacred sites of Nara, where they roam freely and are protected by law.
