Odawara Castle
In 1569, after failing to take the two castles, Shingen nevertheless pressed on to the Hōjō's home castle of Odawara, burning the castle town and withdrawing after three days (Siege of Odawara (1569)). As the forces of Shingen withdrew from repeated failed sieges of Odawara Castle, two of Ujiyasu's seven sons, the brothers Ujiteru and Ujikuni, attacked him in the pass of Mimase (Battle of Mimasetoge), ending the first of the Takeda campaigns against the Hōjō at Sagami province.
