The building that housed the head office of Unitika's forerunner, Amagasaki Spinners, was completed In 1900, ten years after the founding of the company. It has been restored as a museum and is now open to the public. Materials from the company's early days and a substantial collection of photographs are on display. As the oldest extant example of Western-style architecture in Amagasaki, the museum is a registered cultural and historical site, and is one of the city's popular tourist destinations.
