There was an anchorage to the northeast of Mitsuzoin temple in the Edo period. They built a simple bridge to be convenient tor the big boats to go there through the river. So people called it “Yoroyoro Bridge or unsteady bridge,” afterward they named it “Yoro Bridge or care for the aged bridge.”There is the same-name bridge near the port of Eigashima.
