In the heyday of the Ashio copper mine, there were many company houses like "Honzan", "Uenotaira" and "Kodaki" and so on. The roots were made of zinc, and people used communal water-works,rest rooms, and bath rooms. Also, water rates,electric charges, and house repairs were free. Near the company houses, there was a park, a tennis court, a pool,and so on. In addition to this, they used "KARAMI" as a fireproof wall. "KARAMI" is a blac brick used to prevent the spreading of fires.
"Sanyokai" co-ops were also a characteristic of Ashio. They were located near the company houses, so people could buy daily necessities. Some of them are still used today.
