Capybara in Japan: History, Onsen, and Culture

The capybara (Hydrochoerus hydrochaeris), often called the “giant rodent,” fascinates people with its impressive size and gentle nature. Native to South America, it has found a unique place in Japan, where it has become a cultural star—especially thanks to its unexpected love for onsen (hot springs).

Origins of the Capybara in South America

The capybara is native to the tropical and subtropical regions of South America. It can be found in Brazil, Venezuela, Colombia, Argentina, Peru, Paraguay, Uruguay, Ecuador, and Bolivia.

A semi-aquatic animal, it lives near rivers, swamps, and lakes, swimming with remarkable ease thanks to its webbed feet.

In South America, its status is mixed:

  • It is hunted for its meat, often compared to pork, and for its hide, which is used in leather goods.

  • In some areas, it is farmed in a controlled way for food.

  • During the colonial period, the Catholic Church even allowed it to be eaten during Lent, classifying it as “fish” because of its aquatic lifestyle.

  • Yet it is also respected as a symbol of wetland wildlife and an essential link in the ecosystem.

The Arrival of the Capybara in Japan

Capybaras were introduced to Japan in the 1960s, mainly in zoos and animal parks. Their calm character, social behavior, and endearing appearance quickly made them popular with visitors.

But in 1982, they truly won the hearts of the Japanese public. At Izu Shaboten Zoo in Shizuoka Prefecture, keepers discovered that capybaras loved soaking in hot springs during winter. Pictures of these peaceful animals in steaming baths—sometimes surrounded by floating citrus fruits—became a nationwide sensation.

Capybaras and Onsen: A Japanese Tradition

Today, several Japanese zoos and parks hold the famous “capybara onsen” every winter.

  • Thousands of visitors come to watch them relax in hot pools.

  • Japanese and international media broadcast these iconic images.

  • The tradition has strengthened the capybara’s image as a symbol of relaxation and zen-like calm, perfectly aligned with Japanese wellness culture.

Capybaras in Japanese Culture

Capybaras are no longer limited to zoos. They have become true kawaii icons in Japan:

  • Mascots and plush toys, such as the beloved character Kapibara-san.

  • Merchandise, cartoons, and anime appearances.

  • A broader symbol of softness, relaxation, and harmony with nature, echoing Japan’s philosophy of contemplation and slowness.

Capybara Cafés in Japan

In a country where animal cafés are hugely popular (cat cafés, hedgehog cafés, owl cafés…), the capybara has also found its place.

Today, some establishments feature capybara cafés, where visitors can sip tea or coffee while observing, petting, or feeding these giant rodents.

These cafés, especially loved by young Japanese people and tourists, provide a unique experience:

  • Seeing an exotic animal from South America up close.

  • Enjoying a soothing, zen-like moment with capybaras.

  • Taking photos and videos that spread widely across social media.

Capybara cafés perfectly reflect Japan’s fascination with direct contact with cute and unusual animals, integrated into an urban and trendy setting.

Capybara and Otter: Cousins or Just Aquatic Neighbors?

The capybara is sometimes described as a “cousin” of the otter, since both share a semi-aquatic lifestyle and an image of being sociable and endearing animals.
From a scientific perspective, however, they are not from the same family.

The capybara is a rodent from the Caviidae family, closely related to guinea pigs. The otter, on the other hand, belongs to the Mustelidae family, which also includes weasels, badgers, and martens.

They are therefore not direct cousins, but their behavioral similarities explain why they are often associated. Both swim with ease, spend long periods in the water, and inspire public affection. It is fair to call them “aquatic neighbors” rather than true cousins.

Capybaras and the Role of Wildlife in Japanese Zoos

Japan is not only about temples and scenic landscapes. For many visitors, discovering wildlife through zoos and animal parks is also part of the experience. If the capybara has become a star thanks to its hot spring baths, it shares the stage with other fascinating species such as monkeys, bears, lions, and elephants.

Japanese zoos aim to recreate suitable habitats, sometimes very close to the natural environment, to raise awareness of biodiversity and the protection of endangered species. The capybara, living in groups in aquatic enclosures, has thus become an ambassador for a harmonious relationship between humans and animals.

Endangered Species in the Spotlight

Japanese zoos house many mammals and reptiles from five continents. From tigers to rhinos, from lemurs to elephants, each zoo plays a crucial role in conservation. Some institutions even join international programs for breeding and the preservation of endangered species facing extinction.

Visitors can also see wolves, lynx, or deer, all presented in environments designed for their well-being. Although captivity raises debates, Japanese zoos highlight education and awareness, encouraging the protection of wildlife.

Between Domestic and Wild Animals

Some Japanese zoos also welcome so-called domestic animals, allowing children to discover and interact with farm animals such as goats or horses. This proximity between wild and domestic species illustrates the importance of educating the younger generation about animal diversity.

Females, Reproduction, and Protection

Controlled breeding in captivity is another major challenge for zoos. Whether it’s female elephants, tigresses, lionesses, or female capybaras, every birth helps maintain viable populations. Assisted reproduction programs are essential for the survival of severely endangered species such as the rhinoceros.

Conclusion

The success of the capybara in Japanese zoos illustrates the public’s fascination with animals from other continents. But it also reminds us of a larger issue: protecting biodiversity and raising awareness about endangered species. With modern enclosures, breeding programs, and a focus on wildlife conservation, Japanese zoos have become much more than entertainment venues: they are key players in the fight against extinction and in preserving global animal heritage.
