Our relation is feudatory like a father and son.

Goryeo rendered thanks for my ceasefire and for restoring their land and people when I ascended the throne. Especially since my ancestor governed at heaven's commands, innumerable countries from afar disputed our power and slighted our virtue. The sovereigns of small countries, sharing borders with each other, have for a long time been concerned to communicate with each other and become friendly. In 1266, Kublai Khan dispatched emissaries to Japan demanding for Japan to become a vassal and send tribute under a threat of conflict.Ĭherished by the Mandate of Heaven, the Great Mongol Emperor sends this letter to the King of Japan. Letter from Kublai Khan of the "Great Mongol State" (大蒙古國) to the " King of Japan" (日本國王), written in Classical Chinese, the lingua franca in East Asia at the time, dated 8th Month, 1266.

However, it is doubtful if Mongol activities in Sakhalin were part of the effort to invade Japan.

The Mongols also made attempts to subjugate the native peoples of Sakhalin, the Ainu and Nivkh peoples, from 1264 to 1308. The inner circle of the Hōjō clan had become so pre-eminent that they no longer consulted the council of the shogunate ( Hyōjō ( 評定)), the Imperial Court of Kyoto, or their gokenin vassals, and they made their decisions at private meetings in their residences ( yoriai ( 寄合)). Japan was then ruled by the Shikken (shogunate regents) of the Hōjō clan, who had intermarried with and wrested control from Minamoto no Yoriie, shōgun of the Kamakura shogunate, after his death in 1203. Kublai was declared Khagan of the Mongol Empire in 1260 although that was not widely recognized by the Mongols in the west and established his capital at Khanbaliq (within modern Beijing) in 1264. See also: Mongol invasions and conquests and Mongol military tactics and organizationĪfter a series of Mongol invasions of Korea between 12, Goryeo signed a treaty in favor of the Mongols and became a vassal state. One of the most notable technological innovations during the war was the use of explosive, hand-thrown bombs. The invasions were one of the earliest cases of gunpowder warfare outside of China. The invasions are referred to in many works of fiction and are the earliest events for which the word kamikaze ("divine wind") is widely used, originating in reference to the two typhoons faced by the Yuan fleets. Ultimately a failure, the invasion attempts are of macro-historical importance because they set a limit on Mongol expansion and rank as nation-defining events in the history of Japan. Major military efforts were taken by Kublai Khan of the Yuan dynasty in 12 to conquer the Japanese archipelago.
