Maito Fujioka is one of two sons of Hiroshi Fujioka, with his other brother not being part of the entertainment industry. He also has three sisters, one elder and two younger, all of whom are actresses/models within their family agency, Sanki Worldwide.

In preparation for taking on his father's role as Takeshi Hongo / Kamen Rider #1 in the movie Kamen Rider: Beyond Generations, Maito watched the original series to understand the character and consulted with his father for advice.

Fujioka had been interested in the entertainment industry since he was a child, but never actually wanted to be an actor as he wished to pursue music. However, after receiving the offer to portray Sega Sanshiro's son, he made his debut.
