Kenjirō Tsuda and the Voice That Defined a Generation of Anime Antiheroes

Few careers in modern seiyuu history have accumulated weight the way Kenjirō Tsuda’s has. Where other voice actors build range through quantity, Tsuda built his through gravity – a baritone so precise and controlled that it can make a single line of dialogue feel final. Growing up in Osaka and spending his early childhood in Jakarta due to his father’s work, he came back to Japan and eventually studied theater and film at Meiji University, driven by an ambition to direct. That dual identity – performer and filmmaker – never fully separated. It runs through everything he touches.

From Stage Struggles to Seto Kaiba

After university, the path was not smooth. Tsuda spent years doing stage work and barely scraping by before landing his first credited anime role in 1995 with the baseball series H2. The real shift came in 2000 when he stepped into the role of Seto Kaiba in Yu-Gi-Oh! Duel Monsters. Kaiba was not a simple villain – he was arrogant, razor-focused, and strangely compelling, and Tsuda found the exact register to make those qualities magnetic rather than hollow. That performance became the benchmark against which most of his subsequent roles are measured. Konami later honored the role in 2025 by gifting Tsuda with an ultra-rare Blue-Eyes White Dragon card.

Jujutsu Kaisen, Chainsaw Man, and the Golden Decade

The 2010s built Tsuda’s catalog steadily – Mikoto Suoh in K, Joker in Fire Force, Kai Chisaki in My Hero Academia – but it was Kento Nanami in Jujutsu Kaisen that turned him into something approaching a cultural landmark. The stoic, 7:3-ratio sorcerer who quit the profession only to return, disillusioned but resolute, became one of the most mourned characters in recent anime history. Tsuda played him with such contained intensity that fans in Malaysia erected a memorial shrine in Nanami’s honor at Kuantan Beach. In Chainsaw Man, he voiced Kishibe – veteran devil hunter, self-described lover of booze and women, and Denji’s quietly affectionate trainer – adding another layer to his gallery of hardened men carrying something beneath the surface. The 15th Seiyu Awards recognized this run with a Best Lead Actor win in 2021 for his work as Akihito Narihisago in ID: Invaded.

Gaming, Directing, and Taking TikTok to Court

Beyond anime, Tsuda has embedded himself in gaming through Dainsleif in Genshin Impact – the cursed knight of Khaenri’ah, perhaps the game’s most mythologically layered character – and voiced Kylo Ren across the entire Star Wars sequel trilogy for the Japanese dub. His directorial debut came in 2019 with Documentertainment AD-LIVE, a documentary-entertainment hybrid built around the improvisational theater project of the same name. In 2025, he was cast as Figarland Shamrock in One Piece, and in November of that year he filed a lawsuit in Tokyo against TikTok over the alleged unauthorized use of his voice in AI-generated content – a case that, as of mid-2026, remains ongoing and has drawn significant attention to publicity rights in the age of generative AI.
