This article provides thorough explanations of everything you should know before visiting Sumata Gorge: highlights, access methods, hot spring information, best seasons, and nearby tourist attractions.
What is Sumata Gorge? Overview of Shizuoka Prefecture’s Hidden Gem
Sumata Gorge is a valley of the Sumata River, a tributary of the Oi River, surrounded by the deep mountains of the southern Japanese Alps. Located at an elevation of approximately 500-600 meters, it is called a “hidden gem” due to its location, which is about 40 minutes by bus beyond Senzu Station, the terminal of the Oi River Railway.
History and Origins of Sumata Gorge
The area around Sumata Gorge was once a thriving forestry region. In the early Showa period, a forest railway ran through the area for timber transportation. Today, remnants of this history can still be seen in the form of abandoned railway lines and old bridges.
After World War II, dam development in the Oi River system progressed, and in 1968, the Sumata River Dam (officially named: Omagumi Dam) was completed. The artificial lake created by this dam is the present-day Sumata Gorge Lake (Omagumi Lake), which produces the beautiful emerald green lake surface where the Dream Suspension Bridge spans.
Geographic Features of Sumata Gorge
Sumata Gorge is located at the southern tip of the Japanese Alps, surrounded by mountains reaching approximately 1,000 meters in elevation. The area is characterized by a deep V-shaped valley, and the spectacular scenery created by the steep terrain is its main attraction. The clear stream of the Sumata River and lush forests create natural beauty that displays different expressions throughout the four seasons.
Dream Suspension Bridge: Symbolic Icon of Sumata Gorge
The greatest highlight of Sumata Gorge is the “Dream Suspension Bridge.” Spanning 90 meters in length and 8 meters in height, this suspension bridge is built over Sumata Gorge Lake, offering views of the emerald green lake surface from atop the bridge.
Why the Dream Suspension Bridge Was Selected as a “Bridge to Cross Before You Die”
The Dream Suspension Bridge was selected for the “10 Best Pedestrian Suspension Bridges in the World to Cross Before You Die” due to its beauty. The reasons for this selection are as follows:
- Mystical Emerald Green Lake Surface: The water of Sumata Gorge Lake shimmers in blue-green depending on light conditions and season. This color is created by a natural phenomenon resulting from the complex interplay of lake bed composition, water depth, and light reflection.
- Thrilling Suspension Bridge Experience: The number of people allowed to cross at once is limited to a maximum of 10, and the bridge sways as you cross it. While the bridge has a wooden plank floor, the lake surface is visible through the gaps, making it a thrilling experience for those with a fear of heights.
- Harmony with Surrounding Nature: A suspension bridge spanning a deep forest gorge presents a truly hidden gem landscape. Far from urban bustle, visitors can experience a sense of unity with nature in the silence.
Legend of Romance Associated with the Dream Suspension Bridge
The Dream Suspension Bridge carries the legend that “wishes for romantic fulfillment come true if made at the bridge’s center.” Due to this legend, it is also known as a power spot visited by many couples and those wishing for romantic success.
There is a mark at the center of the bridge where wishes are said to be granted. However, during crowded times, be mindful not to stop and to show consideration for other tourists.
