The naval history of Japan began with early interactions with states on the Asian continent in the 3rd century BCE during the Yayoi period. It reached a pre-modern peak of activity during the 16th century, a time of cultural exchange with European powers and extensive trade with the Asian continent. After over two centuries of self-imposed seclusion under the Tokugawa shogunate, Japan's naval technologies became outdated compared to Western navies. The country was forced to abandon its maritime restrictions by American intervention with the Perry Expedition in 1854. This and other events led to the Meiji Restoration, a period of frantic modernization and industrialization accompanied by the re-ascendance of the Emperor's rule and colonialism with the Empire of Japan. Japan became the first industrialized Asian country in 1868, by 1920 the Imperial Japanese Navy was the third largest navy in the world and arguably the most modern at the brink of World War II.

The naval history of Korea dates back thousands of years since the prehistoric times when simple fishing ships were used. Military naval history dates back to the Three Kingdoms period and Unified Silla dynasties of Korea in the 7th century. Because of the constant coastal attacks by the Wa Japanese and barbarian tribes, Korean shipbuilding excelled to counter these threats as a result. During the Unified Silla period, Jang Bogo, a merchant, rose as an admiral and created the first maritime trading within East Asian countries. During the Goryeo dynasty, sturdy wooden ships were built and used to fight pirates. Korean shipbuilding again excelled during the Imjin war, when Admiral Yi defeated the advancing Japanese fleets.
