It feels like a lifetime ago when you couldn’t turn on a Japanese TV without seeing Hiro Mizushima’s face. He was the "it" guy. The definitive ikemen. If you were watching a drama in the late 2000s, he was probably playing a perfect butler, a hot-headed detective, or a literal superhero.
But then, he just... stopped.
Understanding Hiro Mizushima movies and tv shows isn't just about listing credits. It’s about a massive cultural shift in the Japanese entertainment industry. Mizushima didn’t just fade away; he walked out at the absolute peak of his career to choose family and creative freedom over the rigid idol system.
The Roles That Defined an Era
Basically, if you were a fan of J-dramas between 2006 and 2010, Mizushima was your world. He had this specific vibe—polished but capable of being incredibly goofy or intensely cool.
- Kamen Rider Kabuto (2006): This is where it started. He played Souji Tendo. Most "Kamen Rider" leads are rookies, but Tendo was already perfect. He famously said he was the man who would "rule over all." It’s still one of the most popular entries in the franchise, mostly because Mizushima carried it with such ridiculous confidence.
- Hanazakari no Kimitachi e (2007): You probably know this as Hana-Kimi. He wasn’t the lead, but as Minami Nanba, the flirtatious dorm leader, he stole every scene. It was peak ensemble comedy.
- Zettai Kareshi (2008): In Absolute Boyfriend, he played the second lead, Soshi Asamoto. Honestly, a lot of fans (myself included) had major "second lead syndrome" here. He played the corporate heir who actually had a heart, competing against a literal robot for the girl.
- Mei-chan no Shitsuji (2009): This was the height of the craze. He played Rihito, the ultimate S-class butler. It was campy, stylish, and solidified him as the top star in Japan.
Why the Career Path Shifted
In 2010, everything changed. Mizushima married the pop star Ayaka. That sounds normal, right? In the world of Japanese talent agencies, it was a scandal. They got married without getting the green light from their management first.

Soon after, he left his agency, Ken-On. The official word was that he wanted to focus on writing. He actually did it, too. Under his real name, Tomohiro Saito, he wrote a novel called Kagerou and won the 5th Poplar Publishing Grand Prize for Fiction. He even turned down the 20 million yen prize money. That’s a move you don’t see often.
People thought he was blacklisted. Rumors flew that he'd never work in Tokyo again. While he has denied being "banned," the reality is that leaving a major agency in Japan usually means your TV offers dry up instantly.
The Return with Black Butler
He didn't stay gone forever. In 2014, he came back for the live-action Black Butler (Kuroshitsuji) movie. He didn’t just act in it; he was a co-producer and co-screenwriter. He lost a massive amount of weight to play Sebastian Michaelis, looking almost hauntingly thin to match the demonic aesthetic. It was a passion project, but it didn't lead to a full-time return to the drama circuit.

Notable Films:
- Drop (2009): He played Tatsuya, a delinquent with bleached hair and a terrifying temper. It was a total 180 from his butler persona.
- Beck (2010): Based on the famous music manga. He played Ryusuke Minami, the guitar prodigy. Since he lived in Switzerland as a kid, his English was actually good, which made the character feel authentic.
- Kamen Rider Kabuto: God Speed Love (2006): The theatrical spin-off that let him play a more tragic version of his TV character.
Key TV Appearances:
- Tokyo Dogs (2009): A buddy-cop drama with Shun Oguri. This was one of his last big TV roles, and the chemistry between the two was top-tier.
- Mr. Brain (2009): He played the bumbling assistant to Takuya Kimura’s genius scientist.
- Girls (HBO, 2016): This was a shocker. He appeared in Season 5 of Lena Dunham’s show during the Japan episodes. Seeing him in a Western production was a "where have you been?" moment for international fans.
Where is he now? (2026 Perspective)
Honestly, Mizushima seems happier now than he ever was as a TV idol. He’s become a successful entrepreneur and angel investor. If you look at his portfolio, he’s been putting money into startups like Kidbea and Codingal. He’s also a dedicated "papa," often posting about his life with his daughters and his wife, Ayaka.
He also had a YouTube phase with Hiro-Meshi, where he learned to cook Japanese home-style meals. It was incredibly humanizing to see a guy who used to play "the perfect man" struggle to chop a radish.
