|This article is about a/an actor in Kamen Rider 555.|
Handa was notably the first leading Rider actor to start playing the role before the age of 19, beating Tetsuo Kurata as the youngest lead actor cast in the Kamen Rider Series, a record which he would hold for eight years before being eclipsed by a few months by Sota Fukushi when he was cast as the hero of Kamen Rider Fourze, who also started at the age of 18, and then Shun Nishime, who played the titular hero of Kamen Rider Ghost at the age of 17.
On the tenth anniversary of the conclusion of 555, Handa reprised his role as Takumi Inui in Heisei Rider vs. Showa Rider: Kamen Rider Taisen feat. Super Sentai (2014). He also filled in for Riderman in the film. He reprised his role again the following year in Super Hero Taisen GP: Kamen Rider 3 (2015) starring alongside returning actors Yuichi Nakamura/Kamen Rider Zeronos, Tetsuo Kurata/Kamen Rider Black/Black RX, and Kousei Amano/Kamen Rider Garren and D-Video Special: Kamen Rider 4, where he also portrayed the Great Leader of Shocker in human form.
However, 10 years after the first episode's run, he was interviewed by the TV Asashi company and shares his experience of acting as Takumi.
In November of 2017, he recorded a cover of Justiφ's, which was released on his studio album HOMEMADE.
