It is hard to guess what a Japanese marten weights. But we have the answer:
An adult Japanese marten (Martes melampus) on average weights 1000 grams (2.2 lbs).
The Japanese marten is from the family Mustelidae (genus: Martes). When reaching adult age, they grow up to 44.2 cm (1′ 6″).
As a reference: An average human weights in at 62 kg (137 lbs) and reaches an average size of 1.65m (5′ 5″). Humans spend 280 days (40 weeks) in the womb of their mother and reach around 75 years of age.
The Japanese marten (Martes melampus) is a mammal in the marten genus most closely related to the sable. It is 0.5 m (1.5 ft) in length typically, not counting a 20-cm-long tail (7.9 in), and between 1,000 and 1,500 grams (2.2 and 3.3 lb) in weight. Males are generally larger than females. The pelage varies in color from dark brown to dull yellow with a cream-colored throat.Both males and females are territorial, and the size of each individual’s territory depending on food availability. The Japanese marten is omnivorous, preferring meat from fish, frogs, and small birds and mammals, but consuming insects, fruit, and seeds when necessary.The two confirmed subspecies of Japanese marten are:M. m. melampus lives on several of the Japanese islands.M. m. tsuensis is found on Tsushima Island.It has been recorded in the southern Korean Peninsula, but no locality details prove a wild origin and no native population has been confirmed.
