Honestly, you can’t talk about Gintama without talking about the people behind the microphones. It’s one of those rare shows where the cast feels so inseparable from the characters that it’s almost impossible to imagine anyone else doing the job. If you’ve ever watched a serious Shonen anime and suddenly heard a familiar, deadpan voice making a dirty joke, chances are you’ve run into the Gintama Japanese voice actors in the wild.
They aren't just reading lines. They’re surviving a marathon of absurdist comedy, fourth-wall breaking, and sudden, soul-crushing drama. It takes a specific kind of talent to pivot from a gag about Neo Armstrong Cyclone Jet Armstrong Cannons to a tear-jerking speech about samurai pride in under thirty seconds.
Tomokazu Sugita and the Art of Doing Nothing
Most people know Tomokazu Sugita as Gintoki Sakata. It’s his career-defining role, hands down. Before Gintama kicked off in 2006, Sugita was already a rising star, notably voicing Kyon in The Melancholy of Haruhi Suzumiya. But Gintoki is different. Gintoki is lazy. He’s a deadbeat. He’s also a war hero with massive PTSD.
Sugita’s performance is a masterclass in "low-energy" acting. He manages to sound like he’s bored out of his mind while simultaneously delivering some of the fastest, most complex dialogue in anime history. When you hear him as Joseph Joestar in JoJo’s Bizarre Adventure or Gyomei Himejima in Demon Slayer, you can still hear that distinct Gintoki rasp. It’s a voice that carries weight.
Actually, Sugita has joked in interviews about how he’d want Toshiyuki Morikawa to be his substitute if he ever couldn't record. That’s the kind of self-deprecating humor the cast shares. They know the show is ridiculous. They lean into it.
The Shinpachi Problem
Daisuke Sakaguchi is the man behind Shinpachi Shimura. Or, as the show likes to remind us, he’s the man behind the glasses.
Being the "tsukkomi" (straight man) in a comedy duo is a thankless job. You have to scream. A lot. Sakaguchi’s voice is the glue that holds the Yorozuya together. He spent fifteen years shouting at Sugita and Rie Kugimiya, and he’s remarkably good at it. Outside of the Edo period, Sakaguchi has voiced Üso Ewin in Victory Gundam and Leonardo Watch in Blood Blockade Battlefront. He’s got range, but let’s be real: he will always be the human attachment for a pair of glasses to most of us.

Rie Kugimiya: The Queen of Tsundere Goes Rogue
Rie Kugimiya is a legend. Period. She is famous for voicing "tsundere" heroines like Taiga Aisaka in Toradora! and Louise in The Familiar of Zero. If you wanted a pint-sized girl who yells "Baka!" at the protagonist, you called Kugimiya.
Then came Kagura.
Kagura isn't a typical tsundere. She’s an alien who eats like a vacuum, picks her nose, and speaks in a weird "aru" dialect. Kugimiya’s performance as Kagura is arguably her most dynamic work because it threw out the "cute girl" rulebook. She had to voice Kagura through vomiting gags, intense fight scenes, and moments of genuine childhood innocence.
- She won Best Supporting Actress at the 2nd Seiyu Awards.
- She won Best Lead Actress at the 3rd Seiyu Awards.
- She voiced both Kagura and her mother, Kouka, showing she can do "elegant and tragic" just as well as "gross and hilarious."
The Shinsengumi’s Heavy Hitters
You can't mention the Gintama Japanese voice actors without talking about the Shinsengumi. These guys are the "serious" foil to the Yorozuya, but they end up being just as unhinged.
Kazuya Nakai, who voices the mayo-obsessed Toshiro Hijikata, is a fan favorite for a reason. Most people recognize him as Roronoa Zoro from One Piece. He has that deep, gravelly tone that screams "cool rival." The irony is that in Gintama, that cool rival spends half his time running away from ghosts or arguing with a sadistic teenager. Nakai won a Best Supporting Actor award in 2011 for his work on both One Piece and Gintama, proving that his "cool guy" voice is actually incredibly versatile when used for comedy.
Then there’s Kenichi Suzumura as Sogo Okita. Suzumura is married to the incredibly talented Maaya Sakamoto, but in the booth, he’s a master of the monotone sadist. His Sogo is terrifyingly calm. It’s a total 180 from his roles as Lavi in D. Gray-man or Zack Fair in Final Fantasy VII.

The Akira Ishida Phenomenon
If there’s one actor who embodies the "is he a genius or a lunatic?" energy of the show, it’s Akira Ishida. He voices Kotaro Katsura.
Ishida is one of the most respected seiyuu in Japan. We’re talking about Kaworu Nagisa from Neon Genesis Evangelion and Gaara from Naruto. He usually plays the mysterious, beautiful, or tragic characters. In Gintama, he plays a revolutionary who hides inside a giant duck-penguin costume (Elizabeth) and constantly insists, "It’s not Zura, it’s Katsura!"
Ishida’s ability to maintain a dignified, serious tone while saying the most nonsensical things is why Katsura is such a beloved character. He treats the jokes with the same gravity he’d give a Shakespearean monologue. That’s the secret sauce.
Susumu Chiba’s "Gorilla" Legacy
Susumu Chiba voices Isao Kondo. Poor guy. He’s a veteran actor who has voiced Seiji Hayami in Cutie Honey Flash and Sai in Hikaru no Go. And yet, for over a decade, his most famous role involved being called a "stalker gorilla" and being stripped naked for gags.
Chiba’s dedication is admirable. He plays Kondo with such genuine heart that you actually start to root for the guy, despite his questionable life choices. He’s gone on record saying that at first, it felt strange to play someone so different from his usual roles, but he eventually embraced the "fun" of the recording sessions.
Why the Gintama Cast Changed the Industry
Back in the day, anime usually ran continuously, which led to a lot of bad filler episodes. Gintama helped pioneer the "seasonal" approach for long-running Shonen. They took breaks when they ran out of manga material. This allowed the quality of the voice acting to stay consistently high.

The chemistry between these actors is real. They’ve worked together for nearly 20 years. When you hear Gintoki, Shinpachi, and Kagura bickering, that’s not just acting—it’s the sound of three professionals who have grown up together in the industry.
They've even had "gender reversal" arcs where the actors had to swap styles. Sugita had to play "Ginko," and he leaned into a petite, swarming-a-sugar-cube energy. It’s that level of commitment to the bit that makes the Gintama Japanese voice actors stand out in a crowded market.
How to Follow the Cast Today
If you’re looking to dive deeper into their work, start by checking out the Ginpachi-sensei spin-off, which keeps the spirit (and the cast) alive. You can also follow their roles in modern hits:
- Tomokazu Sugita: Check out his role as Reisi Munakata in K or Hoshi in Arakawa Under the Bridge.
- Kazuya Nakai: Don't miss him as Jin Sakai in the Japanese dub of the game Ghost of Tsushima.
- Akira Ishida: Watch Bungo Stray Dogs where he plays Fyodor Dostoevsky to see his "villain" side.
The best way to appreciate these actors is to watch the "Farewell Shinsengumi" arc followed immediately by a "character popularity poll" gag episode. The sheer whiplash of their performances will tell you everything you need to know about why they're the best in the business.
Next Steps for Fans: To truly see the range of this cast, compare their performances in the first season of Gintama (2006) to the final movie, Gintama: The Very Final (2021). You can hear the evolution of their voices as they transitioned from young actors to industry veterans while keeping the same chaotic energy that defined the series for 15 years.
