Complete Guide to Mizugaki Lake and Surroundings (Yamanashi Prefecture) | Autumn Leaves, Hiking, and Access Information
Deep in Hokuto City, Yamanashi Prefecture, nestled between Mount Mizugaki and Mount Kinpu, Mizugaki Lake is an artificial lake created by the Shiokawa Dam, which was completed in 1998. The white arched Kanoe Gorge Bridge serves as its symbol, and this area is beloved by many tourists and hiking enthusiasts for its beautiful scenery that changes with the seasons.
This article provides a thorough explanation of the charm of the Mizugaki Lake area. We offer comprehensive coverage of autumn leaf viewing spots, hiking courses, nearby tourist attractions, and detailed access methods—everything you need to know before visiting.
Basic Information about Mizugaki Lake (Shiokawa Dam)
Overview of Shiokawa Dam and Its Completion History
Mizugaki Lake is a multipurpose dam constructed on the Shiokawa River, which originates from the source streams of Mount Mizugaki and Mount Kinpu. Completed in 1998, this dam serves multiple roles including flood control, securing agricultural water, and supplying tap water. The formal name of the dam lake is Shiokawa Dam, but it is affectionately known as “Mizugaki Lake” in the surrounding area.
The artificial lake created by the dam’s construction harmonizes with the surrounding mountains of the Oku-Chichibu Range, creating a naturally rich landscape. The sight of mountains reflected on the lake’s surface is particularly captivating to visitors.
The Charm of Kanoe Gorge Bridge
The white arched Kanoe Gorge Bridge spanning the lake serves as a symbol of Mizugaki Lake. More than mere transportation infrastructure, this bridge functions as a beautiful landmark integrated with the surrounding natural landscape.
During autumn leaf season in particular, the contrast between mountains dyed red and yellow and the white bridge creates a spectacular scene. Including the bridge’s reflection on the water surface, this area is visited by many camera enthusiasts as a photography spot.
The Role of Mizugaki Lake Visitor Center
The Mizugaki Lake Visitor Center plays an important role as an observation base for this region. The center features exhibits on the area’s nature and history, and you can obtain information about hiking courses.
It also functions as the starting point for the lake circumference course, and we recommend stopping by before enjoying a walk or hike. With restrooms and rest areas fully equipped, you can comfortably begin your nature walk. Additionally, star observation events are occasionally held, providing enjoyment opportunities beyond daytime activities.
Four-Season Attractions Around Mizugaki Lake
Spring Greenery and Alpine Wildflowers
Spring around Mizugaki Lake is a season of beautiful fresh greenery. Trees freed from winter’s harsh cold simultaneously burst into leaf, and vivid green colors the lake shore. This period is abundant with alpine wildflowers, allowing you to enjoy small flowers underfoot while hiking.
The contrast between snowy peaks of the Oku-Chichibu mountains and fresh greenery is magnificent, and a walk in the refreshing air revitalizes both body and mind.
Summer Coolness and Refreshment
The Hokuto City area at high elevation is known as a relatively cool summer retreat. Mizugaki Lake surroundings are no exception, and the area bustles with tourists escaping urban heat.
The breeze crossing the lake surface provides a refreshing sensation, and walking along the tree-shaded promenade makes you forget summer’s heat. The clear water from the source of the Shiokawa glimmers in summer sunlight, offering healing to visitors.
Autumn Leaf Season (Late October to Early November)
The Mizugaki Lake area becomes most vibrant during autumn’s leaf-viewing season. From late October through early November, the surrounding mountains turn red and yellow, and the sight of autumn leaves reflected on the lake surface is breathtakingly beautiful.
The combination of Kanoe Gorge Bridge and autumn foliage is especially spectacular, and this period attracts concentrated crowds of photographers and tourists. The harmony of clear autumn blue sky, red and yellow leaves, white bridge, and lake surface reflection represents the essence of Japan’s autumn beauty.
During leaf season, events like “Masutomi Momiji Festival Walk” are held, with the entire region enveloped in autumn leaf appreciation atmosphere.
Winter Silence and Frozen Beauty
Winter at Mizugaki Lake exudes mysterious charm wrapped in silence. The lake surface sometimes freezes, presenting a completely different appearance from other seasons. The contrast between snow-covered Oku-Chichibu mountains and the frozen lake surface showcases beauty unique to winter.
With fewer visitors, you can spend time quietly facing nature. However, winter requires caution regarding road freezing and snow accumulation, making studless tires or chains essential equipment.
Hiking and Walking Courses Around Mizugaki Lake
Details of the Lake Circumference Course
The lake circumference course starting from the Mizugaki Lake Visitor Center is a popular walking route enjoyable by beginners. Approximately 3-4km in length with hiking time of one to one-and-a-half hours.
The course features relatively flat, well-maintained terrain, making it safe for families. Multiple viewpoints along the way allow viewing the lake, Kanoe Gorge Bridge, and surrounding mountains from various angles. During leaf season especially, changing scenery with each step provides continuous amazement.
Routes Toward Masutomi Hot Spring Area
The route from Mizugaki Lake toward the Masutomi Hot Spring area is also popular. Masutomi Hot Spring is known as one of Japan’s premier radium hot springs and has historically flourished as a healing spa.
From Mizugaki Lake to Masutomi Hot Spring area is approximately 10 minutes by car, though certain sections may close to vehicle traffic during leaf season. In such cases, you access it by walking through tunnels, and the autumn foliage along this walking path is also superb, making walking worthwhile.
Enjoying Valley Beauty Through Country Hiking
The Mizugaki Lake area retains strong country mountain character, with hiking courses along valleys well developed. Routes following the clear Shiokawa stream allow simultaneously enjoying gorge beauty and forest bathing.
Routes toward the Higei settlement feature points of interest including giant trees, allowing natural observation while hiking. However, valley-side routes have slippery sections, so wearing appropriate hiking shoes is recommended.

Base for Mount Mizugaki and Mount Kinpu Climbing

Mount Kinpu (Kinpu-san, 2,599m) is also one of Japan’s 100 Famous Mountains, recommended for those seeking serious mountaineering. The Shiokawa originates from these mountains, and Mizugaki Lake’s water represents these mountains’ pure blessing.
Higei Settlement and Giant Trees
Giant trees believed to be several hundred years old exist in the Higei settlement direction. Turning left at the Higei settlement entrance from Nirasaki-Masutomi Prefectural Road toward the mountain side, you encounter these giant trees.
These ancient trees, which evoke nature’s grandeur and time’s passage, are also known as power spots. Road closures may occur during leaf season, requiring tunnel passage and walking, but the foliage along this path is also beautiful and worthwhile.
