Mount Mitsuishi is a 1,466m peak located in Hachimantai City, Iwate Prefecture. It sits almost exactly in the middle of the Ura-Iwate ridge trail that connects Mount Iwate and Hachimantai, earning its place as one of the Tohoku 100 Famous Mountains. The mountain's shape is characterized by a gentle slope formed by viscous lava flows. Near the summit, the terrain becomes rocky, featuring a prominent large rock that is said to be the origin of the name 'Mitsuishi' (Three Stones), as the summit appears to have three distinct peaks depending on the viewing angle. The surrounding area is home to the Mitsuishi Wetlands, a rich ecosystem of ponds and marshes that preserves a vibrant natural environment.
The history and name of Mount Mitsuishi are deeply tied to its unique topography. The name is said to derive from the fact that the summit appears to consist of three peaks from any direction. Historically, there was a plan to develop the 'Okuchi-to Industrial Development Road' (known as the Okusan-do) for industrial and tourism purposes. While construction progressed in 1964 to connect Shizukuishi and Matsuo, the project was halted due to concerns regarding the destruction of the natural environment, particularly the Mitsuishi Wetlands. Today, the area is strictly preserved as a natural hiking route to protect its delicate ecosystem.
The greatest allure of Mount Mitsuishi is the 360-degree view from the summit. On clear days, hikers can enjoy a sweeping vista of Mount Iwate, Hachimantai, Akita Komagatake, and even Mount Chokai in the distance. The summit area features stone cairns and an expansive, open landscape. Another essential spot is the Mitsuishi Wetlands, where the landscape is dotted with ponds and marshlands. Near the saddle between Mitsuishi-yama and Kobokeyama, you will find the 'Mitsunuma' group of ponds. This entire area is renowned as a treasure trove of alpine flora and high-altitude plants.
The appearance of Mount Mitsuishi changes beautifully with the seasons. During the autumn foliage season, the mountainside is dyed in vibrant colors, creating a stunning spectacle. In early summer, the wetlands come alive with new plant life, showcasing the vitality of nature. The most common route is the 'Amari Hot Spring Course,' which ascends through the Mitsuishi Wetlands. This path is highly popular among hikers for its scenic beauty. Please ensure you have the appropriate gear for the season to enjoy these spectacular views.
Mounting a climb on Mount Mitsuishi is a quintessential hiking experience. Walking the ridge between Mount Iwate and Hachimantai offers a true sense of adventure. Many hikers choose to use the lift at the Amihari Onsen Ski Resort to reach a higher elevation more efficiently, making the trek toward the Mitsuishi Wetlands and the summit more accessible. The silence of the high altitude, the crisp air, and the grand panorama from the rocky summit provide a profound sense of escape from daily life.
The area around the mountain is perfect for post-hike relaxation. Amihari Onsen, Kyukamura Amihari Onsen, Matsukawa Onsen, and Takinoue Onsen are popular destinations for travelers looking to soothe their muscles in natural hot springs after a climb. The region serves as a major outdoor hub for Iwate, offering not just hiking but also excellent bases for camping and trekking throughout the Hachimantai area.
Proper hiking gear is essential. Prepare for a 1,466m altitude by bringing functional clothing that can handle sudden weather changes, including rainwear and warm layers. Sturdy hiking boots are a must. While there is an unmanned shelter called 'Mitsuishi Sanso' near the wetlands, facilities and support are extremely limited, so thorough preparation is vital. To protect the environment, please strictly follow mountain etiquette: carry all trash back out with you and do not pick any plants or disturb the natural scenery. If you plan to use the lift, we recommend checking the operation status and fees in advance.
