In a surprising turn of events, RYOKI Mitsuyama, a 25-year-old member of the popular dance and vocal group BE:FIRST, has been revealed to have been engaged to prominent YouTuber Mari Oono, known as R-chan, according to a report from Shukan Bunshun. The engagement, which reportedly took place three years ago, has since been called off amid allegations involving Mitsuyama.
Mitsuyama, who entered the entertainment industry at the young age of 12, debuted with BE:FIRST in 2021. The group has enjoyed significant success, making appearances at the prestigious NHK Kohaku Uta Gassen for three consecutive years since their debut. Recently, Mitsuyama has also made strides in acting, notably portraying Tomoko's younger brother in the NHK serial TV novel Tiger in the Wings during the first half of 2024.
His acting career has continued to flourish, as he landed the lead role in the film Hold Me Tighter Than Anyone, which was released in February 2025. Furthermore, he is set to appear as a lawyer in the upcoming April 2025 drama series The Illegal Ones of the Igniter Law on TBS.
The engagement to Oono, who boasts approximately 850,000 subscribers on her YouTube channel, was reportedly initiated shortly after Mitsuyama's debut. A friend of the couple shared that the relationship blossomed quickly, leading to Mitsuyama's proposal. The couple even filmed a video announcing their engagement, which has since come under scrutiny.
In a statement, Mitsuyama's agency confirmed the engagement, expressing gratitude for Oono's support during their relationship. "We are thankful for the significant support provided by Ms. Oono," they stated, acknowledging her role in Mitsuyama's life.
However, the engagement has been marred by controversy, as reports surfaced of a personal issue involving Mitsuyama that led to the dissolution of the engagement. Shukan Bunshun has obtained various documents related to the engagement, including the engagement announcement video, a written oath, and an apology video from Mitsuyama.
The publication is set to release more details in its April 23, 2025, online edition and the April 24, 2025, print issue, which will cover the specifics of the written oath, the nature of Mitsuyama's personal issues, and the circumstances surrounding the breakup.
As fans and followers await further developments, the incident has sparked discussions about the pressures faced by public figures in the entertainment industry. The scrutiny that comes with fame can often complicate personal relationships, as seen in this high-profile case.
While Mitsuyama's career continues to rise, with multiple projects lined up, the fallout from his engagement may have lasting implications on his public image. The entertainment community is closely watching how he navigates this challenging period.
With the revelation of the engagement and its subsequent breakup, many are left wondering about the future for both Mitsuyama and Oono. Will they remain friends, or has this incident irrevocably changed their relationship? Only time will tell.
As the story unfolds, fans of BE:FIRST and followers of Oono will undoubtedly be eager to see how both individuals move forward from this chapter in their lives.
