The ginkgo that had stood next to Tsurugaoka Hachiman-gu's stairway almost from its foundation and which appears in almost every old print of the shrine, was completely uprooted and irreparably damaged at 4:40 in the morning on March 10, 2010. According to an expert who analyzed the tree, the fall is likely due to rot. The tree was nicknamed kakure-ichou because according to an Edo period urban legend, a now-famous assassin hid behind it before striking his victim.
Under heavy snow on the evening of February 12, 1219, shogun Minamoto no Sanetomo was coming down from Tsurugaoka Hachiman-gu's Senior Shrine after assisting to a ceremony celebrating his nomination to Udaijin. His nephew Kugyou, son of second shogun Minamoto no Yoriie, came out from next to the stone stairway of the shrine, then suddenly attacked and assassinated him. For his act he was himself beheaded a few hours later, thus bringing the Seiwa Genji line of the Minamoto clan and their rule in Kamakura to a sudden end.
