The Usui Daisan Kyoryo Bridge, often referred to as Meganebashi (Spectacles Bridge) due to its distinctive arch design, is a historic brick railway bridge completed in 1892. It is a significant example of Meiji-era engineering, once part of the Usui Pass railway line, which was a crucial link connecting Tokyo with the Japan Sea coast. Today, it stands as a testament to Japan's early industrialization and offers a picturesque setting for visitors.
Visitors consistently praise the bridge for its photogenic qualities and the serene atmosphere, making it an excellent spot for photography and leisurely walks. Many enjoy the experience of walking across the bridge and exploring the adjacent, well-lit railway tunnels, which add an adventurous element to the visit. The surrounding natural landscape, including small waterfalls and rapids, enhances the scenic appeal, with some reviewers noting the beauty of the drive to the bridge itself. The area is generally described as less crowded than other tourist spots, allowing for a more peaceful experience.
To make the most of your visit, plan to spend approximately 2-3 hours exploring the bridge and the tunnels. Comfortable walking shoes are essential, especially if you intend to walk through the tunnels or explore the surrounding trails. During colder months, particularly in December, visitors should be aware of potentially icy spots on the ground. Bringing a flashlight might be helpful for exploring the tunnels, although they are generally lit. The best time to visit is during daylight hours to fully appreciate the views and ensure safe walking conditions.
The bridge is located in Matsuidamachi, Annaka, Gunma Prefecture. While some visitors opt for a taxi from Karuizawa (which can be costly, around 10,000 yen for a round trip), driving is a popular option, with parking available below the main bridge. From the parking area, it's a pleasant walk up to the bridge. The drive itself is often described as scenic, with twisty roads that some find enjoyable. Public transport options directly to the bridge are limited, making a car or taxi the most practical means of access.
A common complaint, particularly for those relying on public transport, is the relative inaccessibility of the bridge. To mitigate this, consider renting a car or factoring in the cost of a taxi if you are coming from a distant location like Karuizawa. While the tunnels are lit, some sections might be dimly lit, so a personal light source can enhance the experience and safety.
