Sefa-utaki, meaning "purified place of Utaki," is a Shinto Shrine. It is part of the UNESCO World Heritage Site Gusuku Sites and Related Properties of the Kingdom of Ryukyu in Nanjō, Okinawa. Sefa Utaki on Chinen Peninsula has been recognized as a sacred place since the earliest period of Okinawan history.
The shrine area itself comprises a number of caves and overhanging ledges opening to the east and south among towering rock formations of a high promontory over the sea. All buildings have been destroyed, but the outer and inner precincts can still be traced.
