What contributed to the failed mongol invasions of japan?

  In the two invasions, the Mongol ships faced a typhoon that diminished the fleet. And it also demonstrates the inability of them to mount a successful naval invasion.

Explanation:

  The invasions were two the first in 1274 and the second in 1281. They were led by Kublai Khan. The failure of the invasions set a limit on Mongol expansion and was a nation defining event in the history of Japan.
