Toshiko Kasen is a character in the Grand Theft Auto series who appears in Grand Theft Auto: Liberty City Stories (set in 1998). She is the wife of Yakuza leader Kazuki Kasen. She is voiced by Hana Moon, who has also appeared in Sunrise.
Toshiko Kasen was born and raised in Japan, where she met her future husband Kazuki Kasen, later moving to Liberty City in the United States with her husband, who became the leader of the Yakuza in the city. However, Kazuki preferred to spend his time with his men than with Toshiko whom is feeling neglected. She hires Leone Family made man Toni Cipriani to ruin and humiliate her husband after he destroys a Yakuza tank. She first tells Toni to steal a Yakuza munitions delivery, taking them to Phil Cassidy at a small dock in Rockford/Aspatria. Toshiko, happy of giving revenge, hires Toni to destroy the money being moved from Kazuki's casino before taking her to an opera at the Fort Staunton Opera House. After that, the Forelli Family attempt to ambush by smashing the limousine although Toni manages to return her safely to her apartment. Toshiko, having humiliated her husband and shown her allegiances, tells Toni to kill her husband. Toshiko, feeling free, becomes depressed and releases her pet canary into the wild. Toshiko wanted to be "truly free" and commits suicide by falling out of her apartment window and falling on to a car below.
- Despite her holding a gun in the concept art, she appears a very peaceful and tranquil woman in the game, even letting her pet canary out of its cage to fly away into Liberty City before committing suicide.
- She speaks in a radically stereotypical Japanese accent, sometimes she'll pronounce an L as an R.
