Tropical Botanical Garden
Hakodate
A Tropical Oasis in the Heart of Hokkaido
Your Coastal Escape
The Hakodate Tropical Botanical Garden is a delightful contradiction, offering a lush, humid environment in a city known for its snowy winters. Located in the Yunokawa Onsen district, this garden serves as a vibrant sanctuary where tropical life thrives against the backdrop of the Tsugaru Strait. It is a place where the scent of hibiscus meets the salty sea air, providing a sensory retreat for travelers seeking warmth and natural beauty.
Visitors are often surprised by the diversity of experiences packed into this coastal site. From the towering glass pyramid of the main conservatory to the playful antics of the local monkey troop, the garden balances education with pure entertainment. It is more than just a collection of plants; it is a community hub that showcases the unique geothermal gifts of the Hokkaido region.
A Legacy of Warmth and Nature
The History of Hakodate's Green Sanctuary
Established in 1970, the Hakodate Tropical Botanical Garden was designed to utilize the region's abundant geothermal resources. By tapping into the natural hot spring water of the Yunokawa area, the garden was able to maintain a tropical climate year-round without the massive energy costs typically associated with Northern greenhouses. This innovative use of local resources made it a pioneer in sustainable regional tourism.
Over the decades, the garden has evolved from a simple botanical collection into a multi-faceted attraction. It was originally conceived as a way to provide residents and tourists with a "summer" experience even in the depths of January. As the facilities expanded, it became a vital site for the conservation of tropical plant species that would otherwise never survive the harsh Japanese winters.
The most iconic addition to the garden's history came in 1971 when the monkey mountain (Saruyama) was established. A small group of Japanese macaques was brought in, and the staff soon realized the monkeys shared the human love for the local onsen. This discovery turned the garden into a viral sensation, drawing international photographers eager to capture the "bathing monkeys" phenomenon.
In recent years, the garden has undergone several renovations to modernize its facilities while maintaining its nostalgic charm. The glasshouse structures have been reinforced to withstand Hokkaido's heavy snowfall, ensuring the safety of the delicate ecosystems inside. Today, it remains one of the most beloved landmarks in Hakodate, bridging the gap between local geothermal culture and global botany.
Through consistent community support and careful management, the garden has successfully preserved its 50-year legacy. It continues to educate the public on the importance of biodiversity and the unique geology of Hokkaido. For many visitors, a trip here is a nostalgic journey back to a simpler era of Japanese tourism, wrapped in the warmth of the tropics.
Exhibits and Tropical Wonders
Exploring the Glasshouse and Beyond
The centerpiece of the garden is the massive circular greenhouse, which houses approximately 3,000 plants representing 300 different species. As you enter, the sudden rise in humidity and the vibrant palette of greens and reds transport you thousands of miles south. Towering palms, oversized ferns, and climbing vines create a dense canopy that mimics the layered structure of a real rainforest.
Among the botanical highlights are the rare orchids and the "Miracle Fruit," which famously changes the taste of sour foods to sweet. The paths are carefully laid out to guide visitors through different tropical zones, including dedicated areas for succulents and cacti. It is an immersive classroom where signage explains the origins and uses of these exotic specimens, many of which provide the fruits and spices we use daily.
Outside the glasshouse, the "Monkey Mountain" is the primary draw for visitors between December and May. This large enclosure features a pool filled with 40-degree Celsius spring water. Watching the macaques groom each other, play, and nap in the steam is a captivating experience. The monkeys exhibit fascinating social behaviors, and visitors can even purchase snacks to feed them from a designated platform.
For those looking to relax, the garden offers a wonderful "Ashiyu" or footbath. Utilizing the same natural hot spring water as the monkeys, this outdoor facility allows visitors to soak their feet while enjoying the garden scenery. It is a quintessential Japanese experience that combines the health benefits of mineral-rich water with the tranquility of a botanical setting.
Additional facilities include a children's play area featuring battery-powered miniature cars and a small museum space detailing the local ecology. The gift shop offers unique botanical-themed souvenirs and local Hokkaido treats. Every corner of the facility is designed to maximize the visitor's comfort, ensuring that even a short visit provides a comprehensive look at Hakodate’s unique relationship with heat and nature.example of how humans can work in harmony with the natural environment to create something extraordinary.
Three Points of Interest
The Onsen-Loving Macaques
The sight of Japanese macaques soaking in hot springs is usually associated with Nagano, but Hakodate offers its own world-class version. During the winter months, the pool in the monkey enclosure is filled with steaming onsen water, and the resident troop spends hours lounging in the heat. It is a rare opportunity to see these animals in a relaxed, communal state, often with snow falling around them while they stay perfectly warm.
The monkeys are incredibly expressive, and their antics provide endless entertainment. From young infants learning to swim to the elders stoically enjoying the steam, the social dynamics of the troop are on full display. It is widely considered the best place in Hokkaido to witness this unique animal behavior up close.
The "Miracle Fruit" Experience
One of the most unique botanical exhibits in the greenhouse is the Synsepalum dulcificum, better known as the Miracle Fruit. The berry contains a protein called miraculin, which binds to the taste buds and makes sour flavors taste intensely sweet for about half an hour. The garden often highlights this plant, allowing visitors to learn about the fascinating science of taste modification.
This exhibit is a hit with children and science enthusiasts alike. Beyond the Miracle Fruit, the garden showcases several other economically important plants, such as coffee, cocoa, and various citrus fruits. It provides a tangible link between the exotic plants in the greenhouse and the products found on supermarket shelves back home.
Sustainable Geothermal Heating
The garden is a masterclass in functional engineering, as the entire facility is heated by the earth itself. By utilizing the 65-degree Celsius water from the Yunokawa spring, the garden maintains a consistent tropical environment without burning fossil fuels for heat. This makes the attraction an early example of "green" tourism and a testament to the power of volcanic geography.
This geothermal system doesn't just heat the plants; it provides the hot water for the monkey pools and the visitor footbaths. Understanding how the city of Hakodate harnesses this underground energy adds a layer of appreciation to the visit. It is a beautiful
