Toyotomi Hideyoshi's invasions of Korea took place between 1592 and 1598, at the same time as the high point in Azuchi–Momoyama style castle construction within Japan. Many Japanese castles (called "Wajō" 倭城 in Japanese and "Waeseong" in Korean) were built along the southern shores of Korea. All that remains of these castles today are the stone bases.
