Hiroko Kiso’s Place in Japanese Voice Acting

Before ever recording a single line of dialogue, Hiroko Kiso (きそ ひろこ) worked as a pharmacist at a Japanese Red Cross hospital. Born on July 15 in Nara Prefecture, she eventually enrolled at Amusement Media Academy and launched a career that now spans games, anime, dubbing, and singing – an unusual combination that she wears as a point of pride on her own social media, describing herself as “voice actress / actress / singer / pharmacist.”

Monster Hunter and the Apex Connection

Her role as the 3rd Fleet Master in Monster Hunter: World became one of her most-recognized video game performances in Japan, a character who serves as a warm central hub figure throughout the entire game. She carried that same energy into Apex Legends in 2022, voicing Catalyst – the game’s first trans legend – in the Japanese version, giving the character a grounded, commanding presence.

Dubbing Career and Live-Action Work

Kiso has built a strong niche as the consistent Japanese voice for Jessica Williams, dubbing her across the Fantastic Beasts franchise and the Apple TV+ series Shrinking. She has also been the go-to voice for Samantha Morton’s Alpha across multiple seasons of The Walking Dead, and dubbed Gwendoline Christie’s Headmistress Weems in the hit Netflix series Wednesday. Her work extends to Star Wars: The Acolyte, voicing Vernestra Rwoh (Rebecca Henderson) in the Japanese dub.

Kiso holds several professional certifications alongside her voice work: a licensed pharmacist, a Level 2 home helper, a child counselor certification, and a sanitary laboratory technician license. She is also a member of Mensa, the high-IQ society, and has sung the main theme “Lycoris” for the Japanese film Jinrou Game: Prison Break. Her agency is Production Ace.
