Who lead the Mongols against Japan in 1271?

In 1271, Kublai Khan, the grandson of Genghis Khan and the founder of the Yuan Dynasty, led the Mongols against Japan. His ambition was to expand the Mongol Empire by invading Japan, which led to two attempted invasions in 1274 and 1281. However, both attempts were thwarted, notably by typhoons known as "kamikaze" or "divine winds" that destroyed much of the Mongol fleet.
