|This article is about an actor in the Kamen Rider Series.|
Kunihiro Fujioka (藤岡 邦弘, Fujioka Kunihiro), better known by his stage name Hiroshi Fujioka (藤岡 弘、, Fujioka Hiroshi), is a Japanese actor and martial artist best known for his role of Takeshi Hongo in the tokusatsu superhero series Kamen Rider, and later the Sega Saturn mascot Segata Sanshiro. He would reprise the role of Takeshi Hongo several times following the end of the original series, with his most recent appearance being in Saber + Zenkaiger: Superhero Senki.
He also sung the original version of Let's go!! Rider Kick, during the opening of the first 13 episodes of Kamen Rider.
Fujioka was born into to his police officer father and a teacher mother in 1946. At birth, he had pneumonia but miraculously survived thanks to his mother's persistent care. At the age of six, his father taught him martial arts to help him overcome his illness by strengthening his physical and mental health. By the time he began elementary school, Fujioka was often transferring schools due to his father's work, and became the target of bullying. One day, he fought back and seriously injured one of his classmates, and his mother threatened to have them both commit suicide if he didn't stop.
When Fujioka was eleven, his father abandoned the family. From that day, he and his mother survived with less than three meals a day, and lunch money wasn't an option. As he grew up, he worked several part-time jobs to support them and couldn't tell anyone. Fujioka was unable to forgive his father until his later years. In high school, Fujioka joined the judo club and became its captain. Though he was tall and had an ordinary appearance, Fujioka was often targeted by delinquents but perservered thanks to his martial arts and fought back. At the age of 19, Fujioka began his acting career and joined an acting troupe, starring in his first movie and later his first drama.
In 1971, he gained national attention with his role as Takeshi Hongo in Kamen Rider, a role that would define Japanese culture as a whole. He originally performed his own stunts as Kamen Rider 1, and took all of it for granted, thinking that as a martial artist, he could handle it. However as he was filming on a motorcycle and turned into a road that he didn't know was under construction, the bike went out of control and Fujioka's leg got stuck on a utility wire. The bike comes around and hits Fujioka, sending him several meters across the street, shattering his leg and knocking him out. The incident caused a severe bone fracture, which required Fujioka to get long-term bed rest, while he was replaced by Takeshi Sasaki, who was written into the story as Hayato Ichimonji/Kamen Rider 2. Eventually, Fujioka recovered and returned to the show, joining his co-star Sasaki as the Double Riders. From that point going foward, Fujioka did not continue to perform in-suit due to the risks it posed to production.
- Fujioka has five children, four of whom are part of the entertaimment industry. His eldest son, Maito Fujioka portrays a young Takeshi Hongo in Kamen Rider: Beyond Generations.
- Fujioka writes his name with the ideographic comma at the end of his first name, stating that it's "meant to remind me to reconsider myself and what it is that I need to achieve. It shows that I am not yet finished with my tasks and must continue working toward their accomplishment."
