Dog fighting
Dog fighting was considered a way for the samurai to retain their aggressive edge during peaceful times. Several "daimyōs" (feudal lords), such as Chōsokabe Motochika and Yamauchi Yōdō, both from Tosa Province (present-day Kōchi Prefecture), were known to encourage dog fighting. Dog fighting was also popular in Akita Prefecture, which is the origin of the Akita breed.
