The second siege of Odawara took place in 1569. Takeda Shingen attacked Odawara Castle, as a response to Hà Âjà Â's intervention into Shingen invasion of Suruga Province.
In 1568, as a response to Hà Âjà  clan intervention in Takeda invasion of Suruga Province, Takeda Shingen broke the alliance with the Hà Âjà Â, and came into Hà Âjà  territory.
Shingen came into Musashi Province from his home province of Kai, attacking Takiyama and Hachigata Castles, where Ujiyasu's sons repulsed them. After failing at the siege of Takiyama and siege of Hachigata (1568), Takeda Shingen nevertheless moved to Sagami Province against the Hà Âjà  clan capital fortress of Odawara in 1569. The siege lasted only three days, after which the Takeda forces burned the town to the ground and left.
Odawara castle itself did not fall and was still held by the Hojo, end of Shingen's campaign at Sagami Province against Hà Âjà  clan.
