Wa people
Hogong was a minister of Silla in the age of nation-building. It is recorded that he was originally from the Wa people of Japan, though his family name or clan name was unknown to the compiler of the Historical Records of the Three Kingdoms. He was called Hogong (meaning "Duke Bottle Gourd") because he was wearing one or more bottle gourds on his waist when he first came across the sea. He was a very important person in initial Silla because he appeared in stories of primogenitors of all royal families.
