A Japanese voice actor for Bakugo Katsuki is Okamoto Nobuhiko, who played Nishinoya Yu in Haikyuu!! and Shinazugawa Genya in Demon Slayer.
Here’s Kacchan voices in Japanese!
You can hear Kacchan’s voices in Japanese performed by Okamoto in this video.
I think his voice and lines sounds like a villain rather than a hero😅
Though the video doesn’t have English translation, he says like “I’ll make you grilled meat!” and “You’re all mouth!” or “I’ll smash you into pieces as you wish!”
What other characters has he played?
If you like his voice, you can watch and hear his performance with English subtitles.
And this is a promotional video of his solo live tour. You can know how popular he is!
Episodes
Okamoto Nobuhiko’s Shogi (Japanese chess) skill is almost that of a professional’s. He won the professional player though the game was with handicap.
He is also well known for being a Pokemon fanatic, who figures out even hidden parameters of monsters.
