In Real Life
An adult Japanese otter was between 65 and 80 cm long, with a tail measuring 45 to 50 cm. It had a thick, lush coat of dark brown fur with short webbed feet. In addition the river otter has two types/sets of fur.
Data has shown that the river otter would shed their under fur fully from May to August. After the shedding of the under fur, the otter shed their guard hair from August to November. This allowed them to adjust to the seasons changing.
The Japanese River Otter was only found in Japan, mainly in wetland and river areas.
The Japanese otter is nocturnal, only left its den after dark to forage for food. Claiming a territory about ten miles in diameter, it marked the area with its droppings about one to three miles apart and sets up three or four nests under rocks or inside bushes. The otters were always on the move, visiting each den only once every three to four days. They were considered an adult after only one year. They would then venture on their own, but continue in solitude unless ready to mate.
The Japanese river otter primarily feeds on fish, crab, and shrimp; it also ate eels, beetles, watermelons, and sweet potatoes. Many otters spend around six hours to find food because of their difficult living space and their competition for food.
The Japanese river otter had a lifespan of up to 25 years.
- The Japanese river otter was used as medicine to help cure tuberculosis. Typically a dosage that would last about forty days would cost roughly 300 USD.
- These animals were able to stay underwater for over two minutes at a time.
- An important part of Japanese culture, the Japanese River Otter was named the official animal symbol of Japan's Ehime Prefecture; a region of Japan located in northwestern Shikoku.
