Animals in Japan: Native, Endemic & Iconic Species

Animals in Japan range from familiar species such as sika deer and Japanese macaques to animals found nowhere else, including the Japanese serow and Amami rabbit.

Because Japan stretches from snowy Hokkaido to the subtropical islands of Okinawa, its forests, mountains, wetlands, rivers, coasts, and islands support a remarkably diverse range of mammals, birds, reptiles, amphibians, insects, and marine life.

This guide introduces the major animal groups found in Japan, along with iconic, native, and endemic species. You can also follow the links to more detailed guides for each group.

Many of the animals featured on WildWatch Japan have been photographed and observed in the field across Japan, including Hokkaido, Honshu, Amami Oshima, and the southern islands.

What Animals Live in Japan?

Japan is home to a wide range of animals, including mammals, birds, reptiles, amphibians, insects, and marine life.

Some of the best-known animals found in Japan include sika deer, Japanese macaques, Japanese serows, red-crowned cranes, Japanese giant salamanders, and Japanese rhinoceros beetles. Japan is also home to highly localized species such as the Amami rabbit, which is found only on a small group of southern islands.

Japan’s long chain of islands stretches from the cold north of Hokkaido to the subtropical south. This wide range of climates and habitats helps support very different animal communities across the country.

The major animal groups covered in this guide are:

Mammals
Birds
Reptiles
Amphibians
Insects
Marine animals

Below, we’ll look at each group and some of the representative species found in Japan.

Mammals in Japan

Japan is home to mammals ranging from sika deer, Japanese macaques, and wild boars to black bears, foxes, tanuki, and smaller forest species.

Some mammals are especially distinctive to Japan. The Japanese serow and Japanese macaque are endemic to the country, while the Amami rabbit survives only on Amami Oshima and Tokunoshima in southern Japan.

The species you can find also changes greatly by region. Hokkaido is home to brown bears and Ezo red foxes, while the forests of Honshu support animals such as sika deer, Japanese serows, macaques, and Asian black bears.

Birds in Japan

Red-crowned Cranes walking gracefully on the grasslands of Hokkaido, Japan. — Red-crowned Crane (Grus japonensis)

Japan is home to hundreds of bird species, including familiar birds seen around cities and parks, seasonal migrants, and native or endemic species with much more limited ranges.

Among the country’s best-known birds are the Red-crowned Crane, Steller’s Sea Eagle, Japanese Pheasant, Japanese Robin, and Japanese Bush Warbler. The birds you can find vary greatly by region, habitat, and season.

Reptiles in Japan

Japan is home to a variety of reptiles, including snakes, lizards, geckos, and turtles. The species found vary considerably between the main islands and the warmer islands of southwestern Japan.

Familiar reptiles include the Japanese Rat Snake and Japanese Grass Lizard, while venomous snakes such as the Mamushi and Habu are also found in parts of the country.

Amphibians in Japan

Japan is home to a rich variety of amphibians, including frogs, salamanders, and newts. They live in habitats ranging from rice fields and ponds to moist forests and cool mountain streams.

Some amphibians are familiar across large parts of the country, while others have very limited ranges. Japan is especially notable for its salamanders and for unique amphibians found on its southern islands.

Representative species include the Eastern Japanese Tree Frog, Japanese Fire-bellied Newt, Amami Ishikawa’s Frog, and Japanese Giant Salamander.

Insects in Japan

Japan has an exceptionally diverse insect fauna, including beetles, butterflies, moths, dragonflies, cicadas, mantises, and many other groups.

Some insects are closely associated with the Japanese seasons. Rhinoceros beetles and stag beetles are iconic summer insects, while red dragonflies are strongly associated with autumn. Large moths, colorful butterflies, and many other species can also be found across forests, wetlands, fields, and even urban parks.

Marine Animals in Japan

The seas surrounding Japan support a remarkably diverse range of marine life, from whales, dolphins, and sea otters to sea turtles, sharks, fish, and countless marine invertebrates.

Japan’s marine environments vary greatly from north to south. The cold waters around Hokkaido support northern species, while the warmer seas around Okinawa and the southern islands are home to coral reefs, tropical fish, sea turtles, and manta rays.

Marine mammals are also an important part of Japan’s fauna. Whales and dolphins occur in waters around the archipelago, while wild sea otters can be found along parts of eastern Hokkaido.

Native and Endemic Animals in Japan

Japan is home to many native animals, including species that also occur elsewhere in East Asia and others found nowhere else on Earth.

A native species occurs naturally in Japan, but it does not have to be unique to the country. An endemic species, by contrast, is naturally found only in Japan or in a particular part of the Japanese archipelago.

Japan’s long isolation as an island chain has allowed many distinctive animals to evolve, especially in mountain forests and on remote islands such as Amami Oshima, Okinawa, and Iriomote.

Some of Japan’s best-known endemic animals include the Japanese Serow, Japanese Macaque, Amami Rabbit, Okinawa Rail, and Japanese Giant Salamander.

Where to See Wildlife in Japan

Wild animals can be found throughout Japan, but the species you encounter vary greatly by region and habitat.

Hokkaido is especially known for large mammals, cranes, and sea eagles, while the forests and mountains of Honshu are home to animals such as sika deer, Japanese macaques, serows, and Asian black bears. The subtropical islands of Amami and Okinawa support many rare and endemic species found nowhere else.

Firsthand Wildlife Observations Across Japan

Many of the animals featured on WildWatch Japan are species I have personally observed and photographed in the wild.

My field observations have ranged from Red-crowned Cranes, Steller’s Sea Eagles, foxes, pikas, and sea otters in Hokkaido to Japanese serows, deer, bears, frogs, insects, and birds in the mountains and forests of Honshu. Farther south, I have also observed distinctive island wildlife such as the Amami Rabbit on Amami Oshima.

One of the things that stands out most when watching animals across Japan is how quickly the wildlife changes from one region to another. The animals found in snowy Hokkaido can be completely different from those of central Honshu or the subtropical southern islands.

The original photographs and field observations throughout WildWatch Japan are intended to show these animals as they actually live in Japan, rather than simply presenting a list of species.
