A Beautiful All-Hinoki Taiko Bridge
Spanning the clear waters of the Narai River is a magnificent taiko-style arched bridge constructed entirely from Japanese cypress, or hinoki. Hinoki trees more than 300 years old were used in its construction, and the bridge is considered one of the largest wooden bridges in Japan without conventional bridge piers.
The bridge’s graceful arch is created by intricately assembling numerous wooden components. The sophisticated structure is a remarkable example of traditional Japanese craftsmanship, demonstrating the skill required to work with large timber while maintaining both strength and elegance.
The delicate wooden framework can also be admired from beneath the bridge. Looking upward at the complex joinery offers a closer appreciation of the traditional techniques used by the craftsmen who built it.
Connecting Narai-juku with the Modern Road Network
Kiso Ohashi also serves as an important link between National Route 19 and Narai-juku. In this way, the bridge quietly connects the historic post town of the Edo period with the modern transportation network that continues to carry travelers through the Kiso region.
After sunset, the bridge is illuminated, creating a particularly atmospheric scene. The softly lit wooden structure is reflected on the surface of the Narai River, transforming the bridge into an enchanting nighttime landmark.
A Peaceful Riverside Park Surrounded by Nature
Crossing the bridge leads to a spacious waterside park with lawns and seasonal flowers. Visitors can take a leisurely walk while listening to the gentle sound of the clear river flowing nearby.
Unlike many roadside stations, this facility does not have shops or restaurants. Instead, its purpose is to provide a quiet environment where visitors can enjoy the natural scenery and the peaceful atmosphere of the area.
This makes the roadside station an ideal place to pause during a road trip, stretch your legs, and relax beside the river. The absence of commercial facilities is part of its appeal, allowing the bridge, river, trees, and seasonal landscape to take center stage.
Convenient Access for Road Travelers and Train Passengers
Roadside Station Narai Kiso Ohashi is conveniently located along National Route 19, with parking available beside the highway. A spacious parking area is also provided on the waterside park side of the facility.
Visitor facilities include restrooms and a tourist information area, providing basic conveniences for travelers passing through the region.
The site is also accessible by public transportation. Narai Station on the JR Chuo Main Line is within walking distance, while visitors can also reach the area using buses serving the Narai-juku stop on the Chuo Express Bus network and the Narakawa Line of the Shiojiri City community bus.
