What country to the east was attacked but not conquered in 1294?

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.
