Key Findings:

• The defeated Mongol Empire lost most of its naval power - Mongol Naval defense capability declined significantly.
• Korea, which was in charge of shipbuilding for the invasion, also lost its ability to build ships and its ability to defend the sea since a large amount of lumber was cut down.
• On the other hand, in Japan there was no newly-acquired land because it was a defensive war and so the Kamakura Shogunate could not give rewards to gokenin who participated in the battle, and its authority declined.
• Later, taking advantage of the situation, the number of Japanese joining the wokou began to increase, and attacks on the coasts of China and Korea intensified.
• As a result of the war, there was a growing recognition in China that the Japanese were brave and violent and the invasion of Japan was futile. During the Ming Dynasty, invasion into Japan was discussed three times, but it was never carried out considering the result of this war.
