 Three large "Gorintō" stone monuments on the grounds (the graves of a number of the Shimoda "bugyō") are designated as Shimoda City historic monuments.During the visit of Commodore Matthew Calbraith Perry to Shimoda in 1854 in one of the initial attempts by the United States to end the national isolation policy of the Japanese government, the temple was designated as his shore residence.Currently, the road from Ryōsen-ji to the port, which Perry and his men must have used during their stay, is named “Perry Road”, and there are a records that Perry held military parade-style reviewing ceremonies for this men in the precincts of the temple.
