A retired ocean liner named Hikawa-maru is moored at the pier of Yamashita Park in Yokohama city in Kanagawa prefecture. Hikawa-maru was in service back and forth between Yokohama and Seattle in the U.S. from 1930. During World War Ⅱ, she was employed by the Imperial Navy as a hospital ship. The ship struck mines on three separate occasions but avoided being sunk. In the wheelhouse, there is a Shinto altar on which a good luck talisman is displayed. It was given from Hikawa Shrine in Omiya city in Saitama prefecture. Today, we can make a study tour inside Hikawa-maru as a museum. It is designated as important cultural property.
