Did the Samurai ever invade Korea?

Yes, the Samurai, primarily as part of the Japanese military, invaded Korea during two significant campaigns known as the Imjin War or the Japanese invasions of Korea (1592-1598). Led by Toyotomi Hideyoshi, these invasions aimed to conquer Korea and eventually launch an attack on China. The invasions resulted in widespread destruction and loss of life in Korea but ultimately ended in failure, with Korean and Ming Chinese forces successfully repelling the Japanese.
