Current Address
Sumida-ku, Tsutsumidori
A guardian forest of the Suijin no yashiro Shrine (present day Sumidagawa-jinya Shrine). Because it was located on slightly elevated ground, it was not submerged even when the river was swollen, so it was also called "Ukishima" (floating island). It is said that when Minamoto no Yoritomo raised an army, he arrived in this area in 1180 and built the shrine pavilions in wonder of the miracles of the water god Suijin. The spot was important for river traffic, so it was worshipped by the ship owners of the Sumida-gawa River Basin. At present it has been relocated approximately 100 meters to the south.
