Introduction
The tanuki raccoon dog is one of nature’s most surprising animals. They look like raccoons but they are actually dogs. They hibernate like bears. They also star in Japanese folklore as magical tricksters. The tanuki raccoon dog is East Asia’s most charming and problematic canine. They have masked faces and ringed tails. But they are 100% dogs, not raccoons. They come from Japan, Korea, China, and Russia. These fluffy animals have spread across half of Europe just like we explored in our exotic pets guide. As a result, they have earned a spot on the list of the world’s 100 worst invasive species.
The Only Dog That Truly Hibernates
The tanuki raccoon dog is the only dog, belongs to dog family that hibernates. In northern Japan and Siberia, they eat a lot in autumn. Then they sleep underground from November to March. Their body heat drops below 10°C. Their heart slows to just 10 beats per minute.
What Happens When They Wake Up?
When the tanuki raccoon dog wakes up in spring, it has lost half its body weight. However, it is ready to breed straight away. In warmer parts of Japan, they stay active all year. This makes them very hard to control as invaders.Read more fascinating animal facts on our mammals category.
Diet of a Super-Omnivore
The tanuki raccoon dog will eat almost anything — making it a true omnivore. For example, it eats berries, roots, bugs, fish, frogs, and eggs. It also eats small animals and dead animals. Interestingly, it even eats poisonous toads. It uses special saliva to break down the poison. As a result, it can live in forests, farms, wetlands, and cities.

Cultural Superstar: From Yokai to Mario
In Japanese folklore, the tanuki raccoon dog is a magical trickster. In particular, it is known for drumming on its belly. It can also turn leaves into money. Furthermore, it can change shape to look like a monk or even a teapot. The famous statues outside Japanese shops show a tanuki with big features. These are symbols of good luck.
Tanuki in Modern Pop Culture
You have probably seen a tanuki without knowing it. For instance, the Tanooki Suit in Super Mario Bros. 3 is based on the tanuki. Specifically, it uses a special ability to fly through the air.

From Fur Farms to Continental Takeover
The dark chapter began in the 1920s. Specifically, the Soviet Union imported thousands of tanuki for fur farming. Unfortunately, many escaped or were deliberately released into the wild.
How Far Have They Spread?
With no natural enemies in Europe, the raccoon dog spread fast. Today, over 200,000 raccoon dogs are culled annually in Europe according to European wildlife authorities. Nevertheless, they keep moving west. For example, they have reached France, Germany, Poland, Finland, Sweden, and Spain.
What Ecological Damage Do They Cause?
The damage caused by the raccoon dog has been huge, as confirmed by wildlife conservation reports. For more on invasive animals, check out our coati guide.First of all, they eat the eggs and chicks of ground-nesting birds. This causes bird numbers to fall fast. Additionally, they eat frogs and newts. Furthermore, they compete with native crayfish for food and space. On top of that, they carry rabies, ticks, and parasites. As a result, native wildlife is badly affected.
What Is the Situation in Japan Today?
Meanwhile, in Japan the tanuki raccoon dog is stable and well loved. However, it is not a protected species. Instead, it is seen as a common animal. Interestingly, Japan now faces a new problem. North American raccoons were released as pets in the 1970s. Now they are spreading across Japan instead.
