In Ghost of Tsushima, Jin stands up to the Mongolians and will presumably discover a way to repel them by the end of the game. No human analog to Jin exists in real life. The real Mongolian Army was thwarted in Kyushu, Japan by a hurricane in 1274 well after they conquered Tsushima. A different hurricane allegedly thwarted their second invasion attempt in 1281.
Jin is the personification of that hurricane, which was later dubbed "kamikaze" meaning "Divine Wind." At the time, this miracle was chalked up to the thunder god, Raijin giving the Japanese people a helping hand. The kamikaze has since been written by most off as myth, but some modern scientists believe it actually occurred.
Director Nate Fox commented on the change from a hurricane to human last year: "Our hero isn’t a hurricane. He’s a man, and we actually acknowledge that change with his sword that’s engraved with stormwind designs.”
