The Battleship Mikasa, preserved as a memorial museum in Yokosuka, is the world’s only remaining pre-dreadnought battleship and a symbol of Japan’s emergence as a modern naval power, having served as Admiral Heihachiro Togo’s flagship during the 1905 Battle of Tsushima where Japan achieved a stunning victory over Russia’s Baltic Fleet—an event that shifted power in East Asia and marked Japan’s arrival on the global stage; now open to the public, Mikasa allows visitors to explore restored command rooms and officers’ quarters, view original naval artifacts, uniforms, and dramatic battle dioramas, and enjoy sweeping views of Yokosuka Port from the upper deck, offering a powerful and moving encounter with Japan’s naval heritage and the legacy of early 20th-century maritime history.
