Matsudaira Ietada
The first Non Japanese Samurai was an African slave named Yasuke
According to Histoire Ecclesiastique Des Isles Et Royaumes Du Japon, written by François Solier of the Society of Jesus in 1627, Yasuke was a Muslim from Mozambique. Solier’s account may however have been an assumption, as it was written so long after the event and there is no surviving contemporary account that corroborates it.
