  During his reign, Kublai Khan decided to invade Japan. There was no really a justified reason for a such a move, as he was aware that his soldiers will come across a strong defensive line, and economically it made no sense, but that us what he had in mind and tried to achieve it.

  He gathered a big fleet, and send a big Mongol army to invade Japan. The Japanese samurai were aware of it and were waiting on the coast for the enemy to come. The Mongols would have probably won with ease because of the sheer number of the soldiers, but than mother nature took things in her hands. A strong typhoon emerged just as the Mongols were about to reach the Japanese coast, and it destroyed their boats, and most of the soldiers drowned. The ones that managed to reach the coast were slathered, and Kublai Khan was left embarrassed by his actions.

One factor was that the Mongols were used to stepped regions suitable for domesticated horses to go across it; so they mostly relied on their horses and east Asia borders to the pacific were full of mountain ranges, and horses were not that good on abrupt terrains.

Another factor was not being experts on shipbuilding either; and although with the help of Korean naval forces they launched amphibious attacks, they mistakenly came during rainy seasons, and the wind blew from mainland to the pacific for several months.  

So Typhoons blocked their expansion; plus the heat and humidity levels, another reason for them not being able to withstand.

Typhoons, destroyed most of the invasion fleet, and many soldiers drown before arriving to the shores.

Storms were the most significant factor which Japaneses called “Kamikaze” meaning “divine wind".
