The meaning behind the name, Hoshinmon, is “a gate to respect the gods”. This is the last gate on the path that leads to the Una at the Shurijo Seiden. The structure was removed towards the end of the Meiji Period (1868-1912), but the exterior was rebuilt in 1992.
The passageway at the center was only for the king, the Chinese investiture envoys, and other high-ranking individuals. Other officials entered through the passage on both sides.
