For your information, Gionkita Hiroshima Prefectural Senior High School uses Takeda bishi as the school's emblem since the school is located along the foot of Takeda-yama Mountain where there was once the Sato-Kanayama Castle, the residence of Aki-Takeda clan, branch family of Takeda clan.
また、広島県立祇園北高等学校は、校舎が武田氏の傍流安芸武田氏の居城佐東銀山城のあった武田山の麓に立地していることにちなみ、校章には武田菱があしらわれている。
