Introduction
Japan is filled with unique places, but few locations surprise travelers as much as Doai Station — often called “Japan’s deepest underground station” or even “the Mole Station.”
Located between Gunma and Niigata Prefectures, at the foot of the iconic Mount Tanigawa, this mysterious station combines a surreal underground atmosphere with a peaceful mountain landscape. For years, Doai Station was known mainly to hikers, railway fans, and curious explorers who enjoy strange or abandoned places. But recently, it has begun transforming into a small cultural landmark — thanks to a renovated café, improved access, and social media interest.
Doai Station is more than just a railway stop. It is an experience: a long, cold tunnel, endless staircases, complete silence, and a feeling of entering a forgotten world. Yet at the same time, it represents local revitalization, creativity, and the rediscovery of rural Japan’s charm.
If you love hidden gems, offbeat travel, and places with a story, Doai Station absolutely deserves a spot on your Japan itinerary.

1. What Makes Doai Station So Unique?
Doai Station (土合駅) sits along the JR Joetsu Line, which connects Gunma and Niigata through a series of tunnels. What sets this station apart is the deep underground southbound platform — located deep inside a mountain tunnel, far below ground level.
Here are the reasons this place is truly one of a kind:
■ Japan’s deepest underground platform
The southbound platform lies roughly 70 meters below ground, inside a dim, echoing tunnel. Because it was constructed for safety and geographical reasons, passengers must walk through a long corridor before reaching the platform.
■ 486 steps to reach the exit
The most famous feature of Doai Station is the endless staircase — 486 steps leading to the surface.
Climbing the stairs takes about 10 minutes, and many visitors describe it as a mini workout or even a “pilgrimage.” The echoing footsteps and the cold tunnel air create a very unique atmosphere.
■ A completely unmanned station
Doai Station has no staff, no ticket gate, and no ticket vending machines.
Instead, travelers take a “boarding certificate” from a small box and pay for their fare after getting off at their destination. This system is common in rural Japan but rarely seen by international visitors.
■ A mysterious, cinematic atmosphere
Because the station is so quiet, isolated, and echo-filled, many people describe it as:
- “A scene from a horror movie”
- “A forgotten world underground”
- “A time capsule”
Yet, it never feels unsafe — just strangely peaceful.
2. The History Behind the “Mole Station”
Doai Station opened in 1936, designed mainly to support transportation around Tanigawa mountain and the Joetsu Line tunnels. Over time, improvements in train schedules and alternative stops made passenger use decline.
Instead of gaining popularity, Doai became known as:
- One of Japan’s least used stations
- A “haikyo風 (abandoned-ruin-like) station”
- A sacred spot for train enthusiasts
However, it was never completely abandoned. The station continued operating for hikers and locals, even though it averaged only a handful of passengers per day.
The deep platform remained unchanged for decades, making the station a living museum of Japan’s Showa-era railway engineering.
3. The Rebirth of Doai Station: A Local Renovation Story
Recently, Doai Station has experienced a quiet but meaningful rebirth.
■ The Opening of “DOAI VILLAGE” Café
A stylish café and rest space called DOAI VILLAGE opened near the station entrance.
This small project brought:
- Warm lighting and modern design
- Local food, drinks, and coffee
- A relaxing space for hikers and travelers
The contrast is incredible:
After climbing through the cold, silent underground world, visitors arrive at a bright, cozy café — creating a memorable emotional shift.
Reels and TikToks showing the staircase, the tunnel, and the atmospheric lighting have gone viral.
Travelers now come specifically to experience this surreal station.
■ A symbol of Minakami’s revitalization
The Minakami area has been working to improve tourism through collaboration with universities, local groups, and creative projects.
Doai Station is now part of that movement — turning a once-forgotten stop into a cultural attraction.
4. What It Feels Like to Visit Doai Station
Visiting Doai is not just sightseeing — it’s an experience.

4. Climbing back up — the challenge
This is where the legendary 486-step climb begins.
Most people stop halfway to catch their breath. But the effort becomes part of the fun — and the memory.
5. The cozy café above
Finally, sunlight and warmth return as you exit the tunnel. The small café above ground feels like a reward after completing a quest.
