Kyusui Valley

Overview and Charm

Kyusui Valley (Kyusui-kei) is a magnificent canyon located in Kusu Town, Oita Prefecture, formed by the Kusu and Naruko Rivers. The landscape features dramatic cliffs stretching for approximately 2 km along the riverbanks, surrounded by a lush primeval forest of fir, Japanese hemlock, and katsura trees. A unique feature of the area is the 'Jusanmagari' (Thirteen Curves), a series of winding hairpin turns that create a spectacular view of the undulating terrain. Whether you visit during the fresh greenery of spring or the brilliant colors of autumn, the valley offers a constantly changing and captivating natural spectacle.

History and Culture

This region has long been cherished for its rich and untouched natural environment. The deep valley carved by the Kusu River serves as a testament to the power of natural geological formations. The area is deeply connected to the local culture of relaxation, with nearby 'Kyusui Onsen' hot spring facilities allowing visitors to enjoy the healing properties of the hot springs alongside the scenic beauty. Modern infrastructure, such as the Konohe Yume Grand Suspension Bridge, has been developed to allow visitors to safely experience the grandeur of this natural heritage site.

Main Highlights

The primary draw of Kyusui Valley is the striking contrast between the near-vertical cliffs and the crystal-clear river flowing below. The vegetation changes beautifully with the seasons: the fresh greens of spring, the deep emerald of summer, and the fiery reds and golds of autumn. The area also features powerful waterfalls that showcase the raw energy of nature. For a truly breathtaking perspective, visitors can head to the observation points or walk across the Konohe Yume Grand Suspension Bridge—one of Japan's longest pedestrian suspension bridges—to look down upon the dynamic canyon architecture.

Best Times to Visit

While the valley is beautiful year-round, the peak season is from late October to early November when the surrounding mountains are painted in shades of red, orange, and yellow. This is the most popular time for photographers and nature lovers. Early summer is also a wonderful time to witness the vibrant, life-filled greenery. For the best experience, visit during daylight hours to clearly see the movement of the river and the details of the waterfalls from the observation decks.

Activities and Experiences

Visitors can enjoy leisurely walks through the natural paths or experience a sense of adventure by crossing the high-altitude suspension bridge. The view from the bridge offers a thrilling perspective of the vast valley below. After exploring the trails, many visitors choose to relax at one of the nearby hot spring facilities, combining a nature walk with a traditional Japanese wellness experience. It is a perfect place to disconnect and listen to the soothing sounds of the forest.

Surrounding Areas

Kyusui Valley is surrounded by several famous landmarks in Oita and beyond. Ryumon Falls, known for its impressive water flow, is just a 10-minute drive away. If you travel about 42 minutes toward Beppu City, you can experience the famous 'Beppu Hell Tour' (Beppu Jigoku Meguri) to explore unique volcanic hot springs. Additionally, the area is accessible to the spectacular views of Mount Aso's Daikanbo lookout in Kumamoto Prefecture, making it easy to plan a comprehensive tour of the natural wonders of Kyushu.
