Korakukan is a historic theater located in Kosaka Town, Kazuno District, Akita Prefecture, completed in 1910 (Meiji 43). As a National Important Cultural Property, it is highly valued as one of the oldest surviving modern theaters that seamlessly integrates Western architectural elements with traditional Japanese forms. The front of the building features an American-style wooden Gothic design, while the sides and rear maintain a purely Japanese aesthetic, creating a striking architectural fusion of East and West.
The theater's history is deeply intertwined with the development of the Kosaka Mine. It officially opened on August 16, 1910, with a performance by the Tokyo Kabuki troupe led by Onoe Matsuroku. Historically, it served as a cultural hub for the community, even hosting family events for mine employees. Although there were periods when performances ceased, dedicated preservation efforts and restoration work have preserved the site. Today, it stands as a National Important Cultural Property, serving both as a historical monument and a significant cultural tourism resource.

The most remarkable feature is its unique architectural structure. While the exterior boasts Gothic elegance, the interior preserves the traditional layout of a Japanese theater. A standout feature is the "revolving stage" (mawari-butai) with a diameter of 9.73 meters, which is operated manually by four people, showcasing ingenious traditional Japanese stage technology. Visitors can also observe the detailed structural elements, such as the curtain (doncho) painted by the Japanese artist Fukuda Toyoshiro, the tiered seating (sandiki-seki) on the first and second floors, the main flower path (hanamichi), the temporary flower path, and the understage area (naraku).
From April to November, regular theatrical performances are held. Visiting during this period offers a deeper understanding of the theater's functional environment and lively atmosphere. From December to March, depending on the schedule, there may be opportunities to experience the manual operation of the revolving stage when the stage is empty. Please check the seasonal availability, as the experience differs between active performance seasons and sightseeing-focused periods.
