Kensei Mikami (born July 13, 1980) is a versatile Japanese actor and fashion model who first gained widespread attention for his tall, athletic build and sharp, expressive features. He became a staple of "Tokusatsu" culture with his memorable performance as Himuro Gentoku (Kamen Rider Rogue) in Kamen Rider Build (2017–2018), where his character's evolution from a cold antagonist to a quirky, fashion-disaster hero made him a massive fan favorite. Beyond the superhero genre, Mikami has established a robust career in television and film, appearing in high-profile projects such as the live-action Black Butler (2014) and the popular medical drama Doctor-X.
