For three decades, Hiromi Tsuru was the voice of Bulma, from 1986 to 2017. Her sudden passing in 2017 was certainly shocking but the popularity of Bulma and the DBZ franchise meant that Toei would have little choice but to recast the role.
The company has turned to Aya Hisagawa, veteran seiyuu who's previously voiced Sailor Mercury in
Sailor Moon, Kero from
Cardcaptor Sakura and Captain Unohana in
Bleach.
Toei has also confirmed that Tsuru will have one more appearance as Bulma in episode 128 of
Dragon Ball Super before the series concludes with episode 131.
