Sō Sukekuni (宗 助国, 1207 - November 4, 1274) was the Deputy Governor of Tsushima Province during the Kamakura period of Japan.
During the first Mongol invasion of Japan in 1274, Sukekuni led the defence of the island despite only having 80 men.
[1][2] He was the head of the Sō clan, who were the historical rulers of the Tsushima Island.
[3] With 80 mounted samurai and their retinue, Sukekuni confronted an invasion force of what the Sō Shi Kafu describes as 8,000 warriors embarked on 900 ships.
[4] The Mongols landed at 02:00 in the morning on November 4, and ignored the Japanese negotiation attempts, opening fire with their archers and forcing them to retreat.
