The statement of: The Mongols should never have tried to invade Japan is a good and strong statement which can be backed up with numerous facts.
Mongol invasions of Japan happened in 1274.
In 1294, the country to the east that was attacked but not conquered was Japan. This event was part of Kublai Khan's attempts to invade Japan, leading to the Mongol invasions. Despite the initial military efforts, the Mongol forces were repelled, largely due to the fierce resistance from the Japanese defenders and the devastating typhoons known as "kamikaze" that destroyed much of the Mongol fleet.
