Japanese Ruins of Busan

Busan, South Korea

The 400-year-old remains of the samurai invasion of Korea. 


In the late 16th century, Japanese Samurai lords, daimyos, built several castle-like fortresses in Busan during an ambitious plan to conquer Joseon Korea and Ming China. The Koreans, with the later help of the Ming emperor, used guerrilla tactics and flame-throwing armored turtle ships to expel the Japanese from the peninsula. The fortresses, however, remained. 

Several of the 400-year-old castle ruins can be still be seen around the southeast of Korea. They are mostly ivy and root-tangled walls and grassy baileys, situated in peaceful green parks. These ruins were once the site of some of bloody battles between the Koreans, Chinese, and Japanese forces.  

The Japanese invasion of Korea, or Imjin War, began in the spring of 1592 when samurai warriors and several thousand soldiers landed on Korean shores and laid siege to the city of Busan. Samurai scaled the walls of the Busanjin garrison under the cover of arquebus fire and overran the Korean defenses. After the Korean defeat, the Japanese, led by daimyo Toyotomi Hideyoshi, erected a network of Japanese-style fortresses in Korea to prepare for an assault on China.

But Japan would not make it all the way to Beijing. Korean national hero admiral Yi Sun Sin harassed and weakened the Japanese resupply line with turtle ships, armored battleships with dragon-head bows that could shoot fire and cannon balls. On land, the Korean righteous army fought guerrilla warfare against the Japanese. The Ming emperor Wanli sent an army to stop the invaders as they reached and conquered Pyongyang, the modern-day capital of North Korea.  

The Japanese finally retreated back to Japan in 1598. History would repeat itself in 1910 when Japan invaded Korea and later Chinese Manchuria, unleashing events that would split the Korean peninsula in two and affect the whole world today.
