Oyasukyo Gorge is a beautiful V-shaped valley formed by the Minase River, located deep within Yuzawa City, Akita Prefecture. Spanning approximately 8 km, this gorge is recognized as a significant geosite within the Yuza Geo Park, offering a place to experience the wonders of nature up close. The ultimate highlight is the 'Dai-funto' (Great Gushing Spring), where hot water reaching 98°C and white steam erupt violently from cracks in the rock. The sight of the steam rising with a roaring sound provides a direct, powerful sense of the earth's energy. Additionally, the area is well-known for its nearby hot spring inns, making it a perfect destination to enjoy both nature and traditional Japanese hot springs simultaneously.
The unique landscape of this area has been documented since ancient times; even the Edo-period traveler Sugae Masumi recorded the thunderous sounds of water erupting here. The surrounding Oyasukyo Onsen village also boasts a long history of healing. One local legend tells of a crane with a wounded leg that healed itself in these waters, establishing the area as a place of rejuvenation for many generations.
The greatest draw of Oyasukyo is undoubtedly the 'Dai-funto.' The sight of steam and hot water surging from the rock crevices is truly overwhelming. The canyon is also home to numerous waterfalls, such as Fudo Falls and Yakushi Falls, showcasing the exquisite artistry of nature. For those who prefer not to descend the stairs, the Kawahara Yu Bridge—located 60 meters above the canyon floor—allows visitors to enjoy the dynamic views of the gorge and the rising steam from a safe, elevated vantage point. Walking along the designated paths allows you to feel the breath of the earth even more closely.
Oyasukyo offers a completely different face depending on the season. From spring to summer, the lush greenery colors the canyon, making for a refreshing stroll in the cool air. In autumn, vibrant foliage contrasts beautifully with the rocky cliffs. In winter, the area transforms into a frozen wonderland; the heat from the erupting steam melts the snow, which then refreezes to create massive icicles known as 'Shigakko.' During early February, you may witness giant icicles up to 20 meters high and 50 meters wide, often accompanied by illumination events. Please note that the walking paths are closed during the winter season (early November to mid-April), so viewing is primarily done from the Kawahara Yu Bridge.
Exploring the walking paths to feel the energy of nature is a quintessential Oyasukyo experience. Descending near the Dai-funto to feel the intensity of the steam is a unique sensation found nowhere else. After your walk, you can soothe your fatigue in the many nearby hot spring facilities. The area is also a great place to enjoy local delicacies like Inaniwa Udon. For those seeking deeper knowledge, guided tours are available to teach visitors about the local geology and natural history.
The Oyasukyo Onsen village is located right next to the gorge. With various hot spring inns and public baths, it is an ideal location for an overnight stay. Other nearby attractions include the 'Kawarage Hell' (Kawarage Jigoku) and various forest trails, making it a popular route for travelers looking to fully immerse themselves in the natural beauty of the region.
While the walking paths are well-maintained, they involve many stairs, so sturdy walking shoes are essential. Be especially careful during winter or in unstable weather. Since the area near the Dai-funto involves high heat and steam, please stay within the designated safe zones. As this is a natural area, be mindful of local wildlife such as bears or boars. Regarding payments, it is recommended to check in advance if you will be using cash, credit cards, or IC cards at local facilities.
