Japanese Wildlife Guide: A Field Guide to Mammals, Birds, Reptiles & More

If you want to explore Japan’s wildlife by species rather than by destination, start here.

This is the main species index for WildWatch Japan, bringing together mammals, birds, reptiles, amphibians, insects, and other wildlife found across the country.

I have photographed many of the animals featured here while exploring Japan, from Hokkaido and the mountains of Honshu to Sado Island, Amami Oshima, and the southern islands.

The aim is simple: to build a practical Japanese wildlife encyclopedia based around original photography, field observations, and detailed species profiles.

Choose an animal group below, browse a few representative species, and follow the links to explore further.

Insects of Japan

Insects are one of the biggest parts of WildWatch Japan.

Some are instantly recognizable, such as rhinoceros beetles and giant hornets. Others are tiny species that are easy to walk past without ever noticing.

The insect collection is divided into several groups to make it easier to browse.

Beetles
