Japan is a country that surprises you in many ways. You may expect temples, sushi, cherry blossoms, and high-tech cities, but you might not instantly think of squirrels. The question, “Are there squirrels in Japan?” sounds simple, yet the answer opens up a whole world of nature, culture, history, and even personal stories. This blog will take you through every angle of squirrels in Japan, in a way that is not only informative but also enjoyable to read.
I’ll break everything down in detail, so by the end, you’ll understand what types of squirrels live in Japan, where you might see them, how they connect with Japanese culture, and what makes them unique compared to squirrels elsewhere. From my own personal experience, spotting squirrels in Japan is always a little magical because you do not expect them, but when you finally see one darting across a park or climbing a cedar tree, it feels like you’ve been let in on a small natural secret.
Let’s jump in.
The Short Answer: Yes, There Are Squirrels in Japan
Yes, squirrels do live in Japan. But here’s the twist: the types of squirrels in Japan are not exactly the same as the ones you might see in North America or Europe. Instead, Japan has its own native species, along with some unique subspecies that have adapted to the islands’ forests and mountains.
Squirrels in Japan mainly fall into two categories: tree squirrels and flying squirrels. Both are fascinating to observe, but flying squirrels in Japan are especially famous worldwide because of their big, glowing eyes and adorable appearance.
The Different Types of Squirrels Found in Japan
To really understand squirrels in Japan, you need to look at the main species and subspecies. Each one has its own characteristics, habitat, and role in Japan’s natural ecosystem.
Japanese Squirrel (Sciurus lis)
The Japanese squirrel is probably the first animal that comes to mind when people think about squirrels in Japan. This species is native to Honshu, Shikoku, and Kyushu. It does not exist on Hokkaido, which is an interesting fact because Hokkaido has its own type of squirrel.
Japanese squirrels are smaller than the common grey squirrels found in North America. They have reddish-brown fur on their backs, creamy fur on their bellies, and distinctive ear tufts that become especially noticeable in winter.
You’ll often spot them in broadleaf forests, darting around oak and walnut trees. Acorns and nuts form a big part of their diet, and if you’re lucky, you might even see one burying food for the winter.
Eurasian Red Squirrel (Sciurus vulgaris orientis)
In Hokkaido, the Japanese squirrel is absent. Instead, Hokkaido has its own subspecies of the Eurasian red squirrel. This variety is slightly larger and has thicker fur to handle Hokkaido’s freezing winters.
Hokkaido’s red squirrels are extremely photogenic with their fluffy tails and long ear tufts. People in Hokkaido often consider them symbols of the northern wilderness.
Japanese Flying Squirrels
Now comes the most charming group: the flying squirrels of Japan. Unlike tree squirrels, these creatures don’t just climb trees, they glide from branch to branch using a flap of skin stretched between their limbs.
There are two main types of flying squirrels in Japan:
Japanese Dwarf Flying Squirrel (Pteromys momonga)
This tiny squirrel looks like something out of a children’s storybook. With round black eyes, soft grayish fur, and a short tail, the Japanese dwarf flying squirrel is only about 14–20 cm long.
It lives in Honshu and Kyushu, nesting in tree cavities and gliding at night to search for food. Because of its nocturnal habits, you won’t easily see one unless you go squirrel-watching at night.
Japanese Giant Flying Squirrel (Petaurista leucogenys)
On the other end of the scale, the Japanese giant flying squirrel is much larger. It can reach up to 50 cm in length, not even counting its long, bushy tail. When it glides, it can cover distances of 100 meters or more.
These giant flying squirrels are found in Honshu, Shikoku, and Kyushu. Their large body size and wide gliding ability make them fascinating to researchers and nature lovers alike.
Where Can You See Squirrels in Japan?
If you want to see squirrels in Japan, you need to know where to look. Some species are more common in certain regions, while others are rare and harder to spot.
National Parks and Forests
Japan is full of natural reserves where squirrels thrive. Some of the best areas include:
Nikko National Park (Tochigi Prefecture): Famous for cedar trees and shrines, but also home to Japanese squirrels.
Shiretoko National Park (Hokkaido): A natural UNESCO site where you might spot red squirrels along with other northern wildlife.
Nagano Prefecture Forests: Nagano’s mountain areas are known for Japanese giant flying squirrels.
Urban Parks
Surprisingly, you can also see squirrels in city parks. For example:
Ueno Park in Tokyo: While not overflowing with squirrels, occasional sightings happen here.
Kyoto’s Temple Gardens: Squirrels often run across temple grounds, blending into the serene scenery.
Zoos and Wildlife Centers
If you want a guaranteed sighting, zoos like Ueno Zoo and Asahiyama Zoo in Hokkaido feature flying squirrels in their nocturnal animal sections.
How Squirrels Fit into Japanese Culture
Animals often play important roles in culture, and squirrels are no exception. Although squirrels are not as deeply symbolic in Japanese tradition as cranes, foxes, or turtles, they still hold a soft place in the culture.
Folklore and Symbolism
In old Japanese folktales, squirrels sometimes appear as playful forest animals, known for agility and cleverness. Their habit of storing food has occasionally been linked to ideas of preparation and foresight.
Modern Pop Culture
In recent years, the Japanese dwarf flying squirrel has become a global internet sensation. People often share photos of this tiny, wide-eyed squirrel on social media, calling it one of the cutest animals in the world.
What Do Squirrels Eat in Japan?
Japanese squirrels and flying squirrels feed on a wide range of foods depending on the season.
Tree squirrels eat acorns, walnuts, chestnuts, seeds, fruits, and sometimes insects.
Flying squirrels feed on buds, leaves, fruits, and tree bark.
Winter Diets involve hidden caches of nuts and seeds that squirrels cleverly store in the ground or tree hollows.
From my own personal experience, I’ve seen squirrels in Japanese mountain areas scurry away with chestnuts twice the size of their heads. It’s both funny and impressive to watch.
Seasonal Squirrel Behavior in Japan
Squirrels in Japan show distinct seasonal habits.
- Spring: They become more active, searching for fresh buds and seeds.
- Summer: Food is abundant, and you’ll often spot them during early mornings or evenings.
- Autumn: This is their busiest season as they gather and store food. If you want to see squirrel activity at its peak, autumn is the best time.
- Winter: Unlike some animals, squirrels don’t fully hibernate, but their activity slows down. They rely on stored food and spend more time in nests.
Squirrel Conservation in Japan
While squirrels are not endangered in Japan, their habitats face threats. Deforestation and urban expansion reduce the forests they rely on. Flying squirrels, especially, need large, old trees for nesting.
Conservation groups in Japan work to protect these animals by preserving natural forests and raising awareness. Local schools sometimes include squirrel observation programs to teach children about respecting wildlife.
Why Squirrels in Japan Feel So Special
What makes Japanese squirrels stand out compared to those in other countries is their unique adaptation to the islands’ landscapes. The flying squirrels, in particular, give Japan a special place in global wildlife fascination.
Another reason they feel so special is the element of surprise. You don’t always expect to see squirrels when traveling in Japan. Spotting one, especially a flying squirrel gliding through the night, creates a memory that feels almost magical.
Final Thoughts
So, are there squirrels in Japan? Absolutely. From the Japanese squirrel of Honshu to the red squirrels of Hokkaido and the famous flying squirrels that glide through the forests, Japan is home to several squirrel species worth learning about.
Based on my overall experience, once you know about them, you’ll start noticing signs of squirrels more often during your travels in Japan, tiny paw prints, gnawed acorn shells, or sudden movements in the trees.
Squirrels in Japan may not be the headline attraction compared to temples or cherry blossoms, but they offer a window into the country’s quieter natural world. Next time you’re walking through a park or forest in Japan, look up, you might just spot one of these quick, furry residents.
