Conceptual issues of naval warfare between Joseon and Japan during the Japanese Invasion of Korea in 1592.

 The concept of naval warfare is...In short, they fight on the sea, with the aim of eliminating enemy water forces, securing control of the sea, or securing supply routes at sea. Then, let's take a look at what concept of naval warfare the two countries had for the naval forces of Joseon and Japan during the Japanese Invasion of Korea in 1592. First, Joseon... Since the founding of the country, Joseon has had a professional combat group based on water combat by deploying swimming, soldiers, and combatants across the country. During the reign of King Sejong, about half of the total combat power was naval forces, so they were paying attention to securing naval forces, which is presumed to be due to the Japanese invasion at the end of Goryeo. The basic service of the navy was to guard the water, and the battle was also to intercept and strike outside forces invading from the sea, such as naval warfare, which had a relatively close purpose to the concept of naval warfare. Although the theory of defense war has emerged since King Seongjong, the basic concept of naval warfare itself has not disappeared, such as the development of the Panokseon during King Myeongjong's reign, and the perception of the necessity of naval warfare is still reconsidered. When the Japanese Invasion of Korea broke out in 1592, the Joseon Dynasty made efforts to prevent the enemy from entering the naval battle through the naval forces, seeking ways to slow down the advancement of the enemy by blocking Japan's additional troops. Next, Japan... Since the 14th century, Japan has been traveling around the Korean Peninsula and continents under the name of Japanese pirates. Then, at the end of the Warring States Period, most of the famous pirates were incorporated into the formal naval forces under the Daimyo (although Daimyo used to go pirating in the Warring States period). In fact, there seems to be little record of the Japanese naval battle on the sea. Most of them disappear quickly after being on land and looted, or most of the time they fought on land. In any case, the Battle of the White River during the Baekje Revival Army was the first time that Japan fought a large-scale naval battle, and in the Warring States Period, the Battle of Ishiyama by Nobunaga Oda and Moriaga was fought in a naval battle. However, other than this, it seems that there was no naval battle until the Japanese Invasion of Korea in 1592. During the Japanese Invasion of Korea in 1592, Toyotomi Hideyoshi's primary goal to the Japanese naval forces was to smoothly transport the army, and the second goal was to build a fortress in the inland of Joseon according to the circumstances of the war. I don't know exactly how many Japanese naval generals had a concept of naval warfare, but at least in Hideyoshi Toyotomi's head, there was no concept of naval warfare using naval forces to suppress or secure Joseon's control.Hideyoshi may have determined that Joseon was a subordinate country of Tsushima, so he didn't have to worry about the Joseon naval forces...)
