The Imperial Japanese Navy (IJN) was the navy of the Empire of Japan from 1868 to 1945. Following Japan's defeat in World War II, it was replaced with the Japan Maritime Self-Defense Force (JMSDF). Although the IJN participated in several wars, including the Sino-Japanese War, the suppression of the Boxer Rebellion in China, and a decisive victory in the Russo-Japanese war, it is primarily known for its participation in WWII.
