The road that stretches 800 meters straight from the shrine's head was once the approach to the Harumiya Shrine, and was a horse field where many samurai, including the Shimosha Daishu Kinsashi clan, competed in yabusame. The Shimobashi Bridge, which spans the Mitarai River along the way, is said to have been built during the Muromachi period and is the oldest building in Shimosha, and only the mikoshi for the Senza Festival crosses this bridge.
The large granite torii gate at the entrance is estimated to have been built in 1659, and is said to be by the same artist as the Manji stone Buddha outside the precincts.
It appears that the same drawings were given by the Suwa clan when the Harumiya and Akimiya shrines were rebuilt, and although the sizes are different, the layout of the Kagura-den and Worship Hall, the left and right Worship Halls, and the Gohoden buildings are the same. The architecture of both Shunju and Shusha is a competition of carving skills.
