北条時政
Not much is known about Hōjō Tokimasa's early life prior to Minamoto no Yoritomo's arrival in Izu. There is no information about his parents and early childhood, mainly because culture was not concentrated in Izu, but rather in Kyoto. Hōjō Tokimasa was born in 1138 into the influential Hōjō clan in the province of Izu. It's believed that his father was Hōjō Takayoshi, who died in 1159.
