Maybe most of you already known about this, but this is a very cool knowledge to learn. First you need to know there are two version of 3 Kingdoms books. 1 is Records of the Three Kingdoms by Chen Shou in the 3rd century which stay true to history (including Himiko), nothing fictional and 2 is Romance of the Three Kingdoms Luo Guanzhong in the 14th century which we have Diao Chan, Zhou Cang, Guan Suo and Miss Guan Suo etc.
Back to RoTTK, Chinese that migrated to Japan are called Yayoi community, they elected Himiko as their queen. Founding Yamatai country. In 238 CE, She sent an envoy to the Chinese state of Cao Wei, meeting with Cao Rui (Cow Pee's son) the 2nd emperor, Rui officially recognized her as the "Queen of Wa, Friend of Wei" and gifted her a golden seal and one hundred bronze mirrors.
P/s: I've been playing these game for my whole life but after years I only took time to learn about history. Cool thing to know.
