Several structures in the famous Senso-ji shrine complex survived the bombings of 1945. The largest, to the right of the Main Hall, is this Shinto shrine to the Hikonuma brothers and their master, Naji-no-Nakamoto—the putative founders of Senso-ji. In Japan, Buddhism and Shintoism have enjoyed a comfortable coexistence since the former arrived from China in the 6th century. The shrine, built in 1649, is also known as Sanja Sama (Shrine of the Three Guardians). Near the
entrance to Asakusa Shrine is another survivor of World War II: the original east gate to the temple grounds, Niten-mon, built in 1618 for a shrine to Ieyasu Tokugawa and designated by the government as an Important Cultural Property.
