Japanese maritime history spans thousands of years, beginning with early fishing communities and the development of seafaring skills. The Jomon period saw the use of simple boats, while the Yayoi period introduced advanced techniques, including rice cultivation and trade with neighboring regions. During the Heian period, Japan established maritime trade routes with China and Korea, enhancing cultural exchange. The Edo period marked a significant expansion in maritime activities, with the rise of the Sakoku policy, which limited foreign contact but promoted domestic shipping and fishing industries, shaping Japan's unique maritime identity.
