In 1274 the Mongol Empire under Kublai Khan launched the first of two failed invasions of Japan. Eight years before, Kublai had sent a letter to the Japanese emperor (who in the letter he called the "King of Japan"), threatening the use of force unless Japan submitted.
The Japanese did not respond. So it was that five years later the Mongol empire (specifically the Yuan dynasty in China and Korean soldiers form the tributary state of Goryeo) launched an amphibious attack on Japan. The Mongols were however repulsed in their first invasion, and, upon being forced back to their ships, were sunk by a large typhoon.
Another invasion occurred in 1281. Prior to this Kublai Khan had sent emissaries from the Yuan dynasty to Japan to negotiate but the Japanese had them beheaded. Again the Mongols were defeated by stiff resistance and their retreating ships sunk by a typhoon.
The invasions were important moments in both countries, being a defining battle in the history of Japan and setting a limit on Mongol expansion which until then had been unabated.
