Mari Yamamoto

Mari Yamamoto (born February 4, 1986) is a Japanese actress and journalist who has starred in Pachinko, Monarch: Legacy of Monsters, and Rental Family.

Early life and education Born in Japan, Yamamoto moved with her family to London in 1991, before eventually returning to live in Tokyo in 1994 at the age of 8. She described the experience as akin to being an outsider, where she'd be considered "very Japanese everywhere in the world" but "wasn’t quite Japanese enough" in Japan itself.

Yamamoto studied international relations at International Christian University in Tokyo, obtaining her Bachelor of Arts. During this time she was also part of The Bats acting company at The Flea Theater.

Career

She became a producer on the series in its second season. That same year she joined the cast of Apple's Monarch: Legacy of Monsters. In March 2024, she was cast to star opposite Brendan Fraser in the film Rental Family.
