What Are Karen Fukuhara’s Best-Known Roles?
Playing Kimiko in The Boys
Fukuhara portrays Kimiko Miyashiro, also called “The Female,” a silent assassin with superhuman strength and rapid regeneration. The role, which she has played since the show’s debut in 2019, requires nearly all communication through facial expressions and physical movement. Her martial arts background allowed her to perform many of her own stunts. The Boys concluded with its fifth season in 2026.
Role as Katana in Suicide Squad
In 2016, Fukuhara made her film debut as Tatsu Yamashiro / Katana in David Ayer’s Suicide Squad. She trained for two months specifically to wield a sword for the part and performed most of her own stunts. The character is a skilled martial artist who carries a soul-trapping blade.
Appearance in Bullet Train
Contrary to common belief, Fukuhara does not appear in the 2022 film Bullet Train. The character Sakura in that film is played by another actress. The confusion may stem from the film’s Japanese-American ensemble and Fukuhara’s association with action roles.
Fukuhara began Kyokushin Karate in middle school and earned a brown belt before college. Her championship-level training directly prepared her for the stunt-heavy roles of Kimiko and Katana, enabling her to perform complex fight sequences without extensive additional coaching.
