Inoue debuted as an actor in 2008, where he played Keigo Atobe in the Prince of Tennis musicals. One year later, he landed the lead role of Tsukasa in Kamen Rider Decade, where he would continue to play the role in several future crossovers of the character.

From 2015 to 2018, Inoue starred as Jinga in the Garo franchise, portraying the main antagonist in the Yami o Terasu Mono continuity.

He later portrayed Kensei Sumeragi in Road59, a multimedia project by Bushiroad. The project also stars Syuya Sunagawa and Yuki Kimisawa.

In January 2023, he was appointed as the representative director of AIC RIGHTS.^[2]

Inoue was announced to be a guest for Power Morphicon 2024, making this his first convention appearance in the United States.^[3]

Personal Life[]

He is a 1st dan black belt in Taekwondo and in 2015 he demonstrated his skills as a Taekwondo player on Fuji TV's famous Japanese variety show "VS Arashi".^[4]^[5]
He announced his marriage to a Sailor Moon actress Jamie Natsuki on December 2016, with their son born on April 17, 2017.^[6] However they divorced on May 8, 2020, which was confirmed by Inoue himself on Twitter. ^[7]^[8]^[9]

Financial Dispute[]

In 2022, Inoue publicly revealed an ongoing financial dispute between him and his Decade-co-star Kimito Totani, the latter having been lent funds but failed to return them by Inoue's set deadline due to "lack of personal funds at the time."

Notes[]

As with Inoue's role as Jinga in Garo: Goldstorm - Sho, it would become a joke to say that he entered the "World of GARO" during talk shows. According to him, he signed a Decade KamenRide card for Garo director Keita Amamiya.
In 2015, Inoue was among the fans whom played the arcade game Narerunda! Kamen Rider Drive, receiving a souvenir card depicting himself as Kamen Rider Drive.^[25]
For his reappearance in Kamen Rider Zi-O, Inoue wore a brown wig due to his actual hair dyed to silver.
Although, Inoue had stated that his appearance on Kamen Rider Zi-O would be his final reprisal of the role, he returned in 2021 for Rider Time: Zi-O VS Decade & Decade VS Zi-O and in 2024 for Kamen Rider Gotchard: The Future Daybreak.
- Inoue would express his disappointment with Decade Complete Form21's design and ridicule it. ^[26]^[27]
When rumors of Kamen Rider Legend began circulating, this sparked speculation from fans that Inoue would be reprising his role as Tsukasa Kadoya in Gotchard. In July 2023, during a livestream, Inoue acknowledged the speculations but did not further elaborate.^[28] He further teased fans with ambiguous tweets about Gotchard and the upcoming Kamen Rider Legend^[29]^[30], eventually revealing that Kamen Rider Legend was a different character. Inoue recorded brief lines for Decade, who appeared in the special in a brief cameo.
