Sonohyan Utaki Stone Gate (Sonohyan Utaki Ishimon) is located in Shuri Castle Park, roughly 50 meters to the rear of the Shureimon.

For centuries, prior to departing the grounds of Shuri Castle, the King of the Ryukyus stopped at Sonohyan Utaki to pray. In 1519, King Sho Shin ordered a gate to be constructed in front of this sacred grove of trees and commissioned a man named Nishito to accomplish the task. Nishito hailed from Taketomi Island, and his skills as a stonemason were respected and admired throughout the Ryukyu Islands. (He later assumed duties as a minister of the Yaeyama Islands.)
