The Chilling Charm of Osarizawa Mine in Akita
Osarizawa Mine Historic Site is a former mining complex turned theme park located in Kazuno City, Akita Prefecture.
It originally opened in 1982 as “Mine Land Osarizawa” and was rebranded in April 2008 as the “Historic Site Osarizawa Mine.”

Is Osarizawa Mine Haunted?
Some people refer to Osarizawa Mine as a haunted spot in northern Japan. It’s even a popular destination for thrill-seekers and urban explorers.
Officially, there’s no confirmation of any supernatural presence — but once you step into the chilly, dimly lit tunnels, you might feel a little uneasy.
The silence, the underground atmosphere, and the sense of isolation give off a distinct chill...
※ The facility is well-maintained and perfectly safe for visitors.
Hidden Christians and the History of Faith
Osarizawa Mine is also known for being a refuge for “Hidden Christians” during Japan’s Edo period.
In 1612 (Keicho 17), the Tokugawa shogunate began outlawing Christianity, and many believers fled westward.
Some of them sought sanctuary in this mountainous region, working and living secretly within the mines.

If you look closely, you may even find small crosses etched into the rock walls.
While miners were initially protected under local laws, the crackdown intensified. In 1643 (Kanei 20), many were arrested and executed at nearby Shirane Gold Mine.
The Osarizawa Mining Waste Dam Disaster

On November 20, 1936 (Showa 11), the Nakazawa Dam — used to store mine tailings — collapsed.
The flood of sludge engulfed the mining town downstream, killing 362 people and destroying 258 homes.
Shockingly, a second flow of tailings occurred in December, resulting in an additional 12 deaths.
A Kannon Hall and Jizo shrine were later built at a local temple to memorialize the victims.
