Doai Station
Doai Station is an unmanned station on the Joetsu Line of East Japan Railway Company (JR East) located on the border of Gunma and Niigata prefectures. Known as the "Number One Mole Station in Japan" because its platform is located deep underground, a full 70 meters below ground level.
This is a hidden tunnel station in the mountains that only a few people know about. Not many trains stop here if you check the schedule.
After walking through a passageway that feels like a time slip, you reach a super long staircase down to the platform. It feels like it goes on forever!
It took about 10 minutes to get down to the platform, and there was no one waiting for a train. Most people just come to see the station itself.
Going back up takes longer than coming down—you'll need to take breaks on the way up.
It's such a unique and mysterious station, just being in this space was really exciting!
