Kinshūko Lake, Iwate Prefecture | Complete Guide to Submerged Forest and Autumn Foliage Scenic Spots
Located in Nishi-Waga Town, Waga District, Iwate Prefecture, Kinshūko Lake is a beautiful artificial lake formed by the Yuda Dam. The mysterious submerged forest in spring and the brocade-like autumn foliage in fall paint the lake’s surface throughout the seasons, captivating all who visit. Nestled between National Route 107 and the JR Kitakami Line, it has become a popular destination for driving and rail travel.
About Kinshūko Lake | A Scenic Masterpiece Created by Yuda Dam
Kinshūko Lake is an artificial lake created in 1965 by damming the Waga River with the Yuda Dam. The dam has a height of 89.5 meters and employs a gravity arch dam structure. Located near the border between Iwate and Akita prefectures, it spreads along National Route 107 (nicknamed the Shiki Line), an important transportation route connecting the two prefectures.
The lake’s name derives from how the surrounding area becomes beautifully colored like brocade during autumn’s foliage season. The landscape, like a miniature garden, is known as a representative natural beauty of the Tohoku region, attracting many photographers and tourists.
The lake covers approximately 3.4 square kilometers, with abundant nature spreading around it. While serving flood control and power generation functions through the dam, it simultaneously functions as an important tourism resource for the region.
Kinshūko Lake’s Submerged Forest | A Mystical Scenic Wonder Only in Spring
The hidden charm of Kinshūko Lake is the “submerged forest” that appears from spring through early summer. This phenomenon can be seen when the lake’s water level rises significantly due to snowmelt during the season of fresh greenery.
When the Submerged Forest is Visible and Its Mechanism
The submerged forest is most beautiful typically from late April through early June. During this period, snow accumulated on the surrounding mountains melts all at once, and large amounts of water flow into Kinshūko Lake through the Waga River. As a result, the lake’s water level rises several meters above normal, creating a scene where trees along the shoreline become submerged underwater.
The characteristic feature of the submerged forest is the fantastical landscape created by tree trunks and branches protruding from the water’s surface. The interplay of fresh green vegetation, blue lake water, and the silhouettes of submerged trees creates a sensation of having wandered into another world.
Best Viewing Spots for Submerged Forest and How to Enjoy It
The submerged forest can be best observed from observation points along National Route 107 and walking trails established along the lake shore. Particularly in the quiet early morning hours, the lake surface becomes calm like a mirror, allowing you to enjoy the “mirror effect” of the submerged forest reflecting in the water.
For photography, backlighting silhouette photography and compositions emphasizing the fresh greenery are popular. Additionally, combining photographs of the JR Kitakami Line’s red bridge crossing with the submerged forest has become a popular theme among railway enthusiasts and photography lovers.
The submerged forest visible during the season of abundant water and fresh greenery is definitely worth seeing. You can appreciate a serene beauty different from the autumn foliage season.
Kinshūko Lake’s Autumn Foliage | The Seasonal Spectacle That Inspired the Lake’s Name
The greatest charm of Kinshūko Lake is undoubtedly the autumn foliage season. During this season, which inspired the lake’s name, the surrounding mountains are dyed red and yellow, and the scenery reflected in the lake is truly like “brocade.”
Best Foliage Viewing Times and Color Information
Kinshūko Lake’s autumn foliage typically reaches its peak from mid-October through early November. Since the timing of color change varies by elevation and location, you can enjoy foliage for approximately three weeks.
The colors become most vivid in late October, when maple, beech, oak, and other broad-leaved trees turn color all at once. The maple foliage along National Route 107 (Shiki Line) is particularly spectacular, allowing you to enjoy constantly changing scenery while driving.
Best Foliage Viewing Spots
The area around Kinshūko Otaki (Yuda Sand Storage Dam) is the most popular foliage spot. The contrast between the white concrete of the sand storage dam and the autumn foliage is beautiful, and nighttime illumination is also provided. The combination of illuminated foliage and waterfall creates a fantastical landscape recognized as a Japanese night view heritage site.
The area near Waga River’s Makibuchi is also known as a spectacular foliage spot. The natural beauty woven together by the river’s flow and autumn colors soothes the hearts of all who visit.
The combination of the red bridge and JR Kitakami Line should not be missed. The moment when the Kitakami Line train passes over the red bridge framed by autumn foliage is an excellent photo opportunity. We recommend checking train schedules in advance before visiting.
JR Kitakami Line and the Red Bridge | A Must-See Spot for Railway Enthusiasts
When speaking of Kinshūko Lake’s charms, the JR Kitakami Line and the red bridge spanning the lake are indispensable. This combination holds special significance for railway enthusiasts and photography lovers.
The Appeal of the Kitakami Line and Operating Information
The JR Kitakami Line is a local railway connecting Kitakami Station in Kitakami City, Iwate Prefecture, to Yokote Station in Yokote City, Akita Prefecture. In the area around Kinshūko Lake, there is a section running along the lake where passengers can enjoy beautiful scenery from the train windows.
Particularly, “Hotto Yuda Station” serves as the base for Kinshūko Lake tourism and is known for having a hot spring facility inside the station building. Its unique feature of being able to bathe in the hot spring during train waiting times has made it increasingly popular.
Photographing the Red Bridge and Using the Timetable
The red bridge spanning Kinshūko Lake is a photography spot that is particularly striking during the foliage season. The contrast between the bridge’s red color, the surrounding foliage, and the blue lake surface creates beautiful photographs.
The key to photography is confirming the train schedule in advance. Since the JR Kitakami Line has limited frequency, it is important to check the timetable and aim for the moment when the train passes. The moment when the train crosses the bridge is also appealing, allowing you to capture dynamic photographs.
Various angles of photography are possible from observation spots along National Route 107 and the lake shore. The bridge displays different faces depending on the season and time of day, offering new discoveries with each visit.
