Doai Train Station holds the distinction of being Japan's deepest train station, with its northbound platform located 70 meters (230 feet) underground, accessed via a remarkable 486-step staircase. Originally built within the Shimizu Tunnel, which was once Japan's longest, the station is a testament to early 20th-century engineering. While it primarily serves the Joetsu Line, its unique subterranean architecture and remote location have made it a point of interest for railway enthusiasts and curious travelers.
Visitors consistently highlight the station's eerie atmosphere and the impressive descent. Many describe the long, cold, and often windy staircase as an adventure in itself, recommending comfortable shoes and a jacket. The station's unmanned nature adds to its mystique, with some finding it 'creepy' yet fascinating. The recent addition of Doai Village, a glamping facility, and Cafe Mogura has transformed the station from a mere transit point into a destination, offering coffee and pastries in the former ticket office and unique overnight stays. Reviewers appreciate the effort to revitalize the area, providing amenities that were previously lacking.
For a comfortable visit, wear sturdy walking shoes suitable for many stairs. A jacket is advisable, even in warmer months, as the underground platform can be cold and windy. Allow at least 1-2 hours to explore the station, descend to the platform, and perhaps enjoy a coffee at Cafe Mogura. If planning to stay at Doai Village, book well in advance as only four tents are available. Check Cafe Mogura's Instagram (@doaivillage) for their irregular opening hours, as they often close on weekdays.
Doai Station is accessible via the JR East Joetsu Line. It's crucial to check train schedules using a service like Hyperdia, as trains in this rural area are infrequent. The station is unmanned, so there are no staff to assist with tickets or missed connections. Driving is also an option, though parking information is not widely detailed in reviews. Be mindful of the limited facilities if you miss your train, as the area is quite remote.
A common complaint among past visitors was the lack of amenities and the feeling of isolation. With the introduction of Cafe Mogura and Doai Village, these concerns are largely mitigated. However, the infrequency of trains remains a challenge, so careful planning of your arrival and departure times is essential to avoid long waits or being stranded.
