About This Dive Spot

This site on the Miyagi Coast in Chatan, Okinawa sits in front of a water treatment facility and features an underwater seawater intake/outflow device at around 13 m that is often described as UFO-shaped. When the plant is operating, warmer water can be released around the structure, slightly raising the local water temperature. It is dived both from shore and by boat and is known as a macro-focused spot, especially in the cooler months.
