Sika deer can be found all over the main islands of Japan. Meaning, you won’t have to look hard to find one. There is an overabundance of sika deer in the country. This is largely due to their only natural predator, the wolf, going extinct in Japan around a hundred years ago.

They live in the mountains all over the country. They can even be found around the fringes of Tokyo. Brown bears, however, are only found on the northern island of Hokkaido.

Japanese bears are most active in the early mornings and the evening. They hibernate from around December to April, so you won’t be able to find them easily around these times. The omnivorous creatures feed on plants, animals and fish, so be very careful if you stumble across one. Although humans aren’t part of their regular diet, they might attack if you scare or provoke them. They’re faster at running than humans, great climbers and very strong. If you are attacked by a Japanese bear, try to hide behind a tree or a rock and curl up in a ball rather than running away.

7. Goblin Sharks

Animal Classification: Fish

Average Size: 3.7m

Goblin sharks are possibly the scariest animals in Japan. These deep-sea demons look like they came straight out of a horror film. Just like most other sharks, they are solitary animals. These huge deep-sea monsters can grow to about 12 feet long and weigh around 200kg.

They are spotted mostly off the coast of Japan, but they live at the bottom of the ocean. Meaning, you’re unlikely to see one of these rare Japanese animals.

The dwarf flying squirrel is arguably one of the cutest wild animals in Japan. With huge round eyes, they almost look like cartoon characters.

5. Asian Giant Hornets

Growing up to 5cm long with a demonic stinger that’s loaded with potent venom, they’re also known as murder hornets. Whilst very painful, a single sting is not usually lethal. Multiple stings can kill someone, though, even if they aren’t allergic. They have even been known to spray venom into their victims’ eyes in some instances. Nasty!

They are usually found in low mountains and forests, but they tend to make nests near agricultural areas and can pose a threat to farmers. They often make their nests in holes in the ground that have been dug by other animals. In some Japanese mountain villages, people even fry and eat the hornets eggs as a delicacy! And, in the Chubu region, they are eaten as snacks or used as ingredients in drinks. Would you try it?

4. Japanese Giant Salamanders

Animal Classification: Amphibian

Average Size: 1.5m

Known in Japan as Ōsanshōuo, which means “giant pepper fish”, the giant salamander is a nocturnal animal that lives mostly at the bottom of streams and rivers with cool, clear water. It’s called a pepper fish because when it’s threatened, it excretes a strong milk-like substance that smells similar to Japanese pepper. Gross!

They mainly eat insects, frogs and fish, but they have very slow metabolisms, so they can go for weeks without eating sometimes. They’re pretty much blind too, so they detect their prey by sensing vibrations in the water. Giant Salamanders usually live in rivers in rural Japan and can be very hard to find, so you’ll probably need a guide if you want to find them.

3. Tanuki (Raccoon Dogs)

Animal Classification: Mammal

Tanuki are mischievous wild animals that live in Japan. They are a type of Raccoon dog and are viewed very fondly by locals. They’re common throughout the country, even in densely populated areas.

These omnivores will eat almost anything, including birds, insects, lizards, snakes, frogs, crabs, fish and plants. They’ll adapt to their environment and have even been known to rummage through bins.

In Japanese folklore, it is said that Tanuki can shapeshift and appear in human form or as everyday objects. These adorable animals form strong social bonds. They live in monogamous pairs and even cuddle up together when they hibernate in the winter.

2. Martens

Animal Classification: Mammal

Average Size: 50cm

Japanese martens are small wild animals that can be found in forests in Japanese mainlands. They usually live in underground dens and hollowed out trees.

Their offspring are born completely useless; they are blind and deaf! But, within 3 – 4 months, they are mature enough to leave their mothers protection and hunt. In Japanese folklore, it is bad luck if a marten crosses in front of someone.

1. Macaque Monkeys (snow monkeys)

Animal Classification: Mammal

Macaque monkeys are the national animals of Japan. Also known as snow monkeys because they often live in snowy mountain ranges, they have long, thick hair and red faces. These wild animals are very sociable. They live in large groups of 20-30 and are usually led by a dominant male.‎

‎Snow monkeys are very common in Japan. They can be found across the Japanese islands of Honshu, Shikoku and Kyushu, from tropical lowlands to the very cold mountainous regions up to an altitude of 1,500 metres. The only reason they can survive in the snowy mountains is because of the naturally occurring hot springs. They use them to heat up when they get cold. If you want to see them in the wild, there are locations near Tokyo you can find them, but the most famous location is Jigokudani Monkey Park in Nagano Prefecture.
