The Grave of Sugiyama Kengyo

Sugiyama Kengyo (real name, Sugiyama Waichi) was a blind acupuncturist during the Edo period, who believed that Benzaiten had taught him a technique called "tube-needle therapy."
Later, he gained fame for curing the 5th Edo-period shogun, Tokugawa Tsunayoshi and as an expression of his gratitude toward Benzaiten, Sugiyama built a three-story pagoda on the island.
