At the entrance to the temple path stands an ancient well called "Kiyosaki no Ido," which is tied to a legend of a celestial maiden who bathed there. It is said that when the celestial maiden ascended to the heavens, a large moonflower (yūgao) was in bloom. According to one version of the legend, she returned to the heavens by climbing the vine of this enormous moonflower, which is why the well later came to be known as "Yūgao no Ido" (Moonflower Well).
