It is a cotton manufacturing facility equipped with a cotton-mill machinery to make a cotton batting from the raw cotton.

Most of cotton manufacturing facilities these days sell cotton products such as a futon or zabuton and offer the re-fabrication service called ‘uchinaoshi’, which the aged deteriorated cotton batting is turned into a new zabuton. They used to be called ‘wataya’ and sell cotton batting itself to their customers who can make the cotton batting into a zabuton or futon at home by themselves.
