There Was An African Presence In Japan During Nichiren Daishonin's Time
Do you know that the first Shogun of Japan was a Black man by the name of Sakanouye no Tamuramaro? He was a warrior symbolized in Japanese history as "a paragon of military virtues". Sakanouye no Tamuramaro helped the Japanese fight the aborigine people of Japan called Ainu. Ainu traditions tell of "race of Black dwarfs" or Koropokguru which inhabited Japan before the coming of the Ainu. In 791 a battle of the Ainu and Japanese was taking place and the Japanese emperor Kwammu (782-806) summoned Sakanouye no Tamuramaro an "African Warrior". After defeating the Ainu and providing services through-out his career in 797 he was named "Sei-i Tai-Shogun" . Tamuramaro founded a shrine in the district of Izawa in Mutsu dedicated to Hachiman in which he hung up his bows and arrows. Tamuramaro was the first warrior statesmen of Japan. In later ages he was revered by military men as a model commander and as the first recipient of the title Shogun. There is even a Japanese proverb "For a Samurai to be brave he must have a bit of Black blood" One prehistoric and proto-historic populations of Japan were Africoid types, anthropologically described as "Aoshima". The Aoshima appear to be the ancestors of the early Ainu. An ancient tradition points to the conquest of Japan from the southeast by a race of warriors of Black or near Black . Some point this as the ancestors of "Tamuramaro".
