The Taushubetsu River Bridge is a concrete arch bridge located in Lake Nukabira, Kamishihoro Town, Hokkaido. Originally part of the former JNR Shiro Line, this bridge was completed in 1939. Due to the construction of a dam, the surrounding area was flooded, leaving the bridge standing in the middle of the lake. Its most striking feature is how its appearance changes drastically depending on the season and water levels controlled by power generation. During high water periods, much of the bridge is submerged, while during low water periods, its full structure is visible. This unpredictable nature has earned it the nickname 'The Phantom Bridge.' On calm, clear days, the reflection of the arch on the water surface resembles a pair of spectacles, leading locals to call it the 'Megane Bridge' (Spectacles Bridge).
This structure once served as part of the National Railways (JNR) Shiro Line. Built in 1939 over a branch of the Otofuke River, the bridge's fate changed with the construction of the Nukabira Dam for hydroelectric power. As the surrounding area became part of the reservoir, the railway route was diverted in 1955, and the bridge was decommissioned only 16 years after its opening. Although the tracks were removed, the bridge remains a silent monument in the lake. This historical structure has been designated as a Hokkaido Heritage site, serving as a precious piece of the region's history.
The greatest highlight is the shifting expression of the bridge dictated by natural cycles. Because the level of submersion changes, every visit offers a different view. The sight of the arch reflected in the still water creates a profound sense of serenity and harmony with the surrounding Hokkaido wilderness. The contrast between the industrial texture of the concrete and the organic beauty of the natural environment is a unique charm found only here.
The bridge shows a completely different face depending on the season. If you wish to see the full structure, it is highly recommended to check water level information beforehand, as the visibility of the bridge depends on the water depth. The atmosphere also changes with the time of day. On calm mornings with no wind, or during the golden hour of sunset, the reflections on the lake are particularly beautiful and mystical. Please note that during winter, access via forest roads may be restricted due to lack of snow removal.
There are three main ways to experience the bridge. The easiest way is to view it from the 'Taushubetsu Observatory,' located about 8km from Nukabira Onsen. From there, you can observe the bridge from a distance of approximately 750 meters. For a closer look, you can join a paid guided tour organized by the NPO Higashi Daietsu Nature Guide Center. Alternatively, some travelers drive through the forest road to reach the site, but this requires borrowing a key for the forest road gate from the 'Michi-no-Eki Kamishihoro.' Please check requirements in advance as there are specific rules for forest road access.
The area around the bridge is home to the Nukabira Onsen hot spring village, where you can relax in natural hot springs. Nearby accommodations such as Nukabira Kanko Hotel, Sankoso, and Yumotokan offer comfortable stays surrounded by nature. Additionally, the Kamishihoro Railway Museum in the town center is a great place to learn more about the history of the Shiro Line and the context behind this iconic bridge.
