We investigated a water turbine for power to be left in old Garabo spinning mill in Toyota city, Aichi. It was installed in the Taisho era, and it was used until the shutdown in Showa 30's. The mill is converted, but a water turbine and the driveline installed below the floor are still in almost condition at the time of the operation. It is a rare industrial heritage showing that a water turbine was used for the Garabo spinning mill.
