The Imperial Japanese Navy was the naval force of the Empire of Japan from its formal establishment in 1869 during the Meiji Restoration until Japan's 1945 surrender, and rose within just decades to become one of the world's most powerful navies, decisively defeating the Russian Baltic Fleet at the 1905 Battle of Tsushima, a victory that established Japan as a major naval power and remains studied as one of history's most complete naval victories. Built around a doctrine emphasizing decisive fleet battles and, from the interwar period onward, pioneering aircraft carrier aviation under officers such as Isoroku Yamamoto, the Navy carried out the December 1941 surprise attack on Pearl Harbor that brought the United States into World War II, and its carrier forces dominated the early Pacific War before the June 1942 Battle of Midway, where the loss of four fleet carriers marked a decisive turning point against Japan. The Navy's later war years saw catastrophic losses at battles including the Philippine Sea and Leyte Gulf, the latter among the largest naval battles in history, as American industrial capacity and technology increasingly outmatched Japan's ability to replace lost ships and aircrew. The Imperial Japanese Navy was formally dissolved following Japan's surrender in 1945, with its remaining vessels distributed among the Allied powers or scrapped, and postwar Japan's naval capability rebuilt only within the sharply limited, defense-oriented Japan Maritime Self-Defense Force.
