The Former Kosaka Mining Office is a highly significant architectural site located in Kosaka Town, Kazuno District, Akita Prefecture, recognized as an Industrial Heritage of Japan. Constructed in 1905 (Meiji 38), this three-story wooden building features a Western-style design with Renaissance architectural elements and is designated as a national Important Cultural Property.

Although the building was once dismantled, it was meticulously reconstructed and relocated to its current site as part of the "Meiji 100 Years Street Concept" of Kosaka Town. Every detail, from the white plaster walls to the copper-plated roofing, was restored based on original blueprints to faithfully preserve the historical landscape.
