If you have ever seen a video of blissful capybaras soaking in a hot bath with citrus fruits bobbing around them, chances are you were looking at footage from Nagasaki Bio Park. It is one of the most iconic images of Kyushu travel.
However, for parents planning a trip to Japan with toddlers or younger children, the concept of a “Bio Park” can be a little daunting. Unlike a traditional zoo where animals are safely behind glass or moats, Nagasaki Bio Park is designed on the philosophy of “harmony and symbiosis.” In practical terms, this means many animals roam freely among the visitors.
Is it safe for a three-year-old? Will the capybaras bite? Is the park stroller-friendly? In this comprehensive review, we will break down everything parents need to know about visiting this unique attraction, specifically focusing on safety and logistics for families.

What is Nagasaki Bio Park?
Nagasaki Bio Park is not your standard city zoo. Located in Saikai City, about an hour to an hour and a half drive from Nagasaki City, it feels more like a botanical garden that happens to be inhabited by animals.
The park spans a massive area and is designed so that visitors walk through the animal habitats rather than just looking at them. There are very few cages. You enter the zone, and suddenly, you are sharing the path with lemurs, kangaroos, and, of course, the famous capybaras.
For families who have visited other animal attractions in the region, such as the Fukuoka City Zoo with Kids: The Complete Family Guide & Tips, the difference here is the level of immersion. At Fukuoka City Zoo, you observe. At Bio Park, you interact.
The “Touch and Feed” Philosophy
The primary draw here is feeding the animals. Capsules of food are available throughout the park (usually 100 to 200 yen), allowing children to hand-feed raccoons, squirrel monkeys, and capybaras. This is magical for older kids, but it requires vigilance for parents of toddlers.
The Star Attraction: The Capybara Zone
Let’s address the main question: Is the Capybara Zone safe for small children?
The short answer is: Yes, but with close supervision.
The capybaras at Nagasaki Bio Park are generally very docile. They are accustomed to humans and spend much of their time sleeping or eating. However, they are the world’s largest rodents, and they can be surprisingly heavy and solid.
Safety Tips for Toddlers and Capybaras
- Mind the Size Difference: A full-grown capybara can weigh up to 60kg (over 130 lbs). If one decides to stand up or turn around quickly, a small toddler could be knocked over. Keep your child within arm’s reach.
- Feeding Etiquette: The capybaras are food-motivated. If your child is holding bamboo leaves (sold for feeding), the capybaras will approach. They have large, orange teeth. While they are not aggressive, they may nip at the food enthusiastically. We recommend parents hold the bamboo or assist the child in holding the very end of the stick to keep little fingers away from mouths.
- The Winter Onsen: If you are visiting in winter (typically December through February), you will see the famous Capybara Onsen. During this time, the animals are often clustered in the warm water. This is actually the safest time for toddlers to observe them, as the animals are stationary and blissfully relaxed.
- The “Zone” Boundaries: There is a gate to enter the Capybara area. If your child becomes frightened, you can easily retreat outside the gate while still having a great view of the animals.
Beyond Capybaras: Other Animal Encounters
While the capybaras get the Instagram fame, other zones require different safety considerations for parents.
The Squirrel Monkey Forest
This is often the most chaotic and fun part of the park. Small squirrel monkeys run freely through the trees and—frequently—onto the shoulders of visitors.
- Safety Note: These monkeys are lightning-fast thieves. Before entering, secure all loose items. Toddlers holding snacks or shiny toys might have them snatched. It is generally safe, but the sudden movement of a monkey jumping on a backpack can startle young children.
The Kangaroo Hill
Here, you walk through a hillside populated by kangaroos and wallabies. Unlike the monkeys, the kangaroos are usually laid back and often sleeping. They are generally very safe for children to pet gently on the back, making this a great “starter” interaction for nervous kids.
PAW (Pet Animal World)
Located near the entrance, PAW is an indoor/outdoor facility that requires a small extra fee (or a combo ticket). It features domestic animals like dogs, cats, guinea pigs, and rabbits.
- Why it’s great for toddlers: If the capybaras seem too big, PAW offers a controlled environment with familiar, smaller animals. It’s a great place to take a break from the outdoor heat or cold.
Comparing Animal Experiences in Kyushu
If your family’s main goal in Kyushu is seeing animals, you might be weighing Nagasaki Bio Park against other major attractions.
If you are looking for a “Safari” experience where you view large predators like lions and bears from the safety of a vehicle, you should look toward Oita Prefecture. We have a detailed comparison and guide for that experience here: African Safari with Kids: Jungle Bus Tips & Discounts.
Nagasaki Bio Park is strictly about herbivores and smaller animals (though they do have hippos, which are behind safe barriers!). The focus in Nagasaki is on contact, whereas African Safari is about scale and viewing wilder animals.
Practical Logistics for Parents
Stroller Accessibility
Nagasaki Bio Park is built on the side of a hill. The typical route involves a lot of walking, totaling about 2 kilometers if you do the whole loop.
- The Path: The main paths are paved and stroller-friendly, but they can be steep. Be prepared for a workout.
- Rental: Strollers are available for rent at the entrance, but bring your own if you have a comfortable, rugged one.
- The “Insectarium” Shortcut: There are some shortcuts, but generally, you are committed to the loop once you start.
Food and Dining
There are restaurants inside the park, but the menu is standard zoo fare (curry, udon, burgers).
- Family Tip: There are plenty of benches and picnic areas. To save money and ensure your picky eaters are happy, consider bringing a bento lunch.
- Hydration: Kyushu summers are hot and humid. There is little shade in some of the open zones (like the zebra or kangaroo areas). Vending machines are available, but carrying water bottles is essential.
Getting There
This is the trickiest part of the Bio Park experience. It is somewhat isolated.
- By Car: This is the best option for families. It allows you to control your schedule and store strollers/luggage easily.
- By Shuttle Bus: There is a free shuttle bus from Huis Ten Bosch if you are staying there, but it requires reservation.
- By Public Bus: You can take a bus from Nagasaki Station, but it takes about 80 minutes. For a family with small kids, a long bus ride followed by a 2km walk around the zoo can be exhausting.

Verdict: Is it Worth the Trip?
For animal-loving families, Nagasaki Bio Park is a must-visit. The ability to look a lemur in the eye or scratch a capybara under the chin creates memories that standard zoos simply cannot match.
While the “free-range” concept requires parents to be more vigilant than usual, the animals are well-acclimated to humans. As long as you respect their space and supervise your toddlers closely in the Capybara and Monkey zones, it is a safe and incredibly rewarding experience.
What to Pack for Bio Park
- Comfortable Sneakers: You will be walking on hills.
- Hand Sanitizer: While there are sinks specifically for washing hands after feeding animals, having your own sanitizer is convenient.
- 100 Yen Coins: You will want plenty of coins for the animal feed capsules.
- Sun Protection: Hats and sunscreen are vital, even in spring and autumn.
