A Japanese voice actor for Ryomen Sukuna in Jujutsu Kaisen is Suwabe Junichi, who played Atobe Keigo in The Prince of Tennis, Greed in Fullmetal Alchemist and Aizawa Shota in My Hero Academia.
You can hear him acting Sukuna on the video below, the battle scene of Sukuna vs. special grade cursed spirit!
What other anime characters has he played?
Suwabe Junichi is one of the most popular voice actors in Japan and he’s performed countless anime characters. This is the video that introduce the part of them. I’m sure you’ve heard some of them if you’re an anime fan!
Suwabe has a rare background for a voice actor. He started his career as a performer after working several companies. His performance for Atobe Keigo in The Prince of Tennis made him famous and he got to play various anime characters.
He’s also putting effort into playing music, not only singing but including composition. Here’s a video of old Japanese anime songs (all the songs were released around 40 years ago) medley he sings. For me, it sounds like Sukuna or teacher Aizawa is singing🤣
