Last updated 2026-09-24 — If you have time to spare after visiting the Railway Culture Village, why not embark on a nostalgic walking tour? Although the Nagano Shinkansen has cut off the direct road between Yokokawa and Kumahira, it has also created a unique tourism opportunity. A walking trail built on an abandoned railway stretches all the way from Yokokawa to Kumahira, passing through the famous autumn foliage spot, the "Kagami Bridge," and the popular wedding photo location, Usui Lake. If you get tired from walking, you can take a break at Isobe Onsen to soothe your body and mind with its carbonated spring water rich in hydrogen sulfide.

If you have time to spare after visiting the Railway Culture Village, why not embark on a nostalgic walking tour? Although the Nagano Shinkansen has cut off the direct road between Yokokawa and Kumahira, it has also created a unique tourism opportunity. A walking trail built on an abandoned railway stretches all the way from Yokokawa to Kumahira, passing through the famous autumn foliage spot, the "Kagami Bridge," and the popular wedding photo location, Usui Lake.

The Kagami Bridge was built in Showa 25 (1950), located 4.8 kilometers from the Railway Culture Village. It is an arch bridge made of 2 million red bricks, standing 31 meters tall and stretching 91 meters in length. In autumn, the panoramic view of the mountains and valleys covered in red leaves from the bridge is breathtaking. Drivers can also enjoy a close-up view of the Kagami Bridge from the highway, where the red leaves complement the mountain scenery, offering a unique charm. To celebrate the autumn foliage season, the Kagami Bridge holds a two-week night illumination event every November. Those who wish to see its different beauty can plan their visit accordingly.

Usui Lake is an artificial lake formed by constructing a dam at the confluence of the Nakao River and the Usui River. It takes about 20 minutes to walk around the lake. Visiting in autumn also offers the chance to try kayaking on the lake, paddling through the Small Kagami Bridge and looking back at the colorful mix of red, yellow, and green foliage on the shore – a truly picturesque scene. The experience takes about 30 minutes, and since paddling may splash water on you, it's recommended not to bring a camera. Coaches will take photos for you at designated spots.

When it comes to the Isobe area, the most famous attractions are its hot springs and senbei (rice crackers). In Isobe Park, Annaka City, there stands a hot spring monument – the earliest hot spring symbol in Japan, originating from a land dispute during the Edo period when the shogun was asked to rule on the ownership of the hot spring area. At the Isobe Onsen Kaikan, you can try the only sand sauna in Gunma Prefecture. Your whole body is buried under warm sand with only your head exposed, allowing the heat to envelop you. Within just five minutes, you’ll be sweating profusely. Afterward, drink three cups of hot tea, which will keep you warm throughout the cold winter day.

Isobe Senbei

Isobe Senbei is made from hot spring water, flour, and salt, with 20 shops along the hot spring street each offering unique textures – some are crispy, while others are soft. One of the long-standing shops, Eigensendo, even has a master making the senbei on-site. If you visit during production hours, you might get to taste freshly made senbei straight from the master’s hands.

Suzume no Yado Isobe Garden Hotel

For those needing accommodation, Suzume no Yado Isobe Garden Hotel is a great choice. The hotel is themed around the local folktale "The Tongue-Cut Sparrow," which took place near Isobe Onsen. The hotel also regularly stages life-sized puppet shows that tell the story of the sparrow repaying kindness. Isobe Onsen is known for its iron-rich, hydrogen sulfide, and carbonated mineral water, which helps relieve neuralgia, muscle pain, and joint pain, making it the perfect choice for an evening soak.
