Since mid-May, Imagawa Yoshimoto set out westward from Jumogawa, passing through Enshū, and then arrived at Okazaki Castle in Sanhe for a brief rest, gathering the prominent clans of the entire Sanhe Province to accompany him to Kyoto, and meanwhile leaving part of the Imagawa family's forces to garrison Okazaki Castle to ensure the security of his rear line.
Soon after, he set out from Okazaki Castle, with Matsudaira Mototaka, Ii Naomasa, and Katsuyama Nobuhide commanding a vanguard of twelve thousand men, officially entering Owari; Yoshimoto himself then lodged at Takagai Castle, preparing a route through Dagao, Nagami, Atsuta, Nagano Castle,, and Qingzhou, before entering Minoh.
On the whole, his battle plan was coming off smoothly. Matsudaira Mototaka had successfully rescued the besieged Dagao City and, following the momentum, took out Marune Stronghold. Ii Naomasa, for his part, succeeded in capturing Jiuzhen Stronghold, and wiped out all nearby forces of the Oda Family.
