It is hard to guess what a Japanese macaque weights. But we have the answer:
An adult Japanese macaque (Macaca fuscata) on average weights 10.11 kg (22.28 lbs).
The Japanese macaque is from the family Cercopithecidae (genus: Macaca). It is usually born with about 502 grams (1.11 lbs). They can live for up to 33 years. When reaching adult age, they grow up to 82.7 cm (2′ 9″). On average, Japanese macaques can have babies 1 times per year with a litter size of 1.
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 macaque (; Macaca fuscata), also known as the snow monkey, is a terrestrial Old World monkey species that is native to Japan. They get their name “snow monkey” because some live in areas where snow covers the ground for months each year – no other non-human primate is more northern-living, nor lives in a colder climate. Individuals have brown-grey fur, pinkish-red faces, and short tails. Two subspecies are known.In Japan, the species is known as Nihonzaru (ニホンザル, a combination of Nihon 日本 “Japan” + saru 猿 “monkey”) to distinguish it from other primates, but the Japanese macaque is very familiar in Japan, so when Japanese people simply say saru, they usually have in mind the Japanese macaque.
