It is said that the Takeda family switched their support to Kagekatsu UESUGI due to the following differences in the terms they were offered in exchange for their support: Kagetora UESUGI wanted the Takeda family to cede the northern Shinano area and the Kozuke Numata area to him in exchange for his entering into an alliance with them, but Kagekatsu offered to pay 20,000 ryo in gold to the Takeda family, who were in need of war funds (according to "Koyogunkan"), and turn over Numata-jo Castle in Kozuke Province to them if they entered into an alliance (virtually a vassalage) with him.
武田家が上杉景勝支持に転じた理由として、上杉景虎が同盟するなら北信濃一帯及び上野沼田一帯の譲渡を求めたのに対し、景勝は武田家との同盟（事実上の臣従）と軍資金に困窮していた武田家に2万両とも云われる黄金を支払い（『甲陽軍鑑』による）、上野国沼田城を譲るという条件面での差があったとされる。
