On the Nagaoka to Honjo route, the main train service utilized is the Joetsu Line, which is operated by the East Japan Railway Company (JR East). The limited express train called the Tanigawa provides an efficient and rapid journey, reaching speeds of up to 120 km/h (75 mph). This service covers the distance in approximately 1 hour and 30 minutes. In contrast, local trains on this line may take significantly longer due to more frequent stops, making the Tanigawa the preferred option for travelers looking for a quicker journey.
The Tanigawa offers both Ordinary and Green class seating, allowing travelers to select their desired level of comfort. While the ordinary seating provides a standard experience, the Green class enhances the travel experience with more spacious seating and added amenities. Travelers will find onboard services and facilities such as snack vending machines, restrooms, and air conditioning for a comfortable ride.
