Located in the northwestern region of Utsunomiya, Japan, the Oya History Museum is a must-see attraction.
The museum offers an extensive look at the mining history of this former stone quarry.
While the history of this area is interesting, it's the underground caverns that get the most attention. These underground halls reach a depth of 30 meters and cover more than 20,000 square meters.
The hallways are illuminated with different colored lights and some rooms are designated for specific purposes, such as the chapel and stage area. Not only is this museum a popular tourist attraction, but it is the spot for various events, such as weddings, concerts, and productions, throughout the year.
Remember to bring a jacket when visiting the museum because the temperature can drop in the underground halls.
