The Mikasa was launched in 1902 as the only ship of her class into the Imperial Japanese Navy. She served extensively in the Russo-Japanese War, taking part in the bombardment of Port Arthur and the Battle of Tsushima. During World War I, Mikasa served as a costal defense ship. In 1922, under a specific exception in the Washington Naval Treaty, Mikasa was allowed to become a museum ship and, in 1926, she opened to the public. She is the only pre-dreadnought battleship afloat.
