Ryūto Sakuma

Ryūto Sakuma is a Japanese idol, actor, and singer currently active under STARTO ENTERTAINMENT. Born on September 30, 2002, in Sagamihara City, Kanagawa Prefecture, he serves as a member of the newly formed junior unit ACEes. Standing at 179 cm with blood type O, Sakuma has established himself as a versatile performer within the highly competitive Johnny's Jr. system.

His career trajectory highlights a successful transition from idol singing to dramatic acting. He gained significant attention for his roles in the TV drama DIVE!! and the film Unlock Your Heart. In early 2025, following a major reorganization of Johnny's Jr. units, he was announced as a founding member of ACEes alongside Hidaka Ukisho, Yuto Nasu, Ryuusei Fukada, and Ryuga Sato. [edit]

Sakuma was raised in Sagamihara, Kanagawa, where his entry into the entertainment industry began not through self-initiative but via his mother. She recognized his interest in the arts and encouraged him to audition after discovering he was already a devoted fan of the legendary group Arashi. This fandom served as his primary motivation for joining the agency.

On February 11, 2013, at just ten years old, Sakuma officially joined Johnny & Associates talent agency (now STARTO). He immediately entered the rigorous training program for junior idols. His early years were spent performing in various stage shows and concerts across Japan as part of the initial unit Miyake-kun before being selected as a core member of the newly formed group HiHi Jets in 2015. Unlike many peers who might have pursued formal acting or music schools during this period, his entire education occurred within the agency's training environment.

The path to stardom required immense patience and discipline. For over a decade, he honed his vocal and dance skills while appearing in numerous live events. A notable challenge arose in late 2019 when he and fellow member Ryo Hashimoto temporarily refrained from all activities due to stress-related health issues. Their eventual return marked a turning point in his resilience and commitment to the profession. [edit]

Sakuma's breakthrough moment came as he solidified his position within HiHi Jets, eventually becoming one of the unit's lead vocalists and dancers. The group released multiple singles and performed sold-out concerts throughout Japan between 2015 and 2024. However, his true expansion into mainstream media arrived in 2021 when he secured a leading role in the TV drama DIVE!!. The series utilized HiHi Jets' theme song, bridging his idol work with his acting aspirations alongside co-stars Mizuki Inoue and Yuto Takahashi.

Following the drama, he appeared in the film Unlock Your Heart in 2021, receiving critical attention for his portrayal in the teen drama genre. His acting portfolio continued to grow with a role in the 2024 film Ito and Her Brother. In March 2025, he starred in the live-action adaptation of My Love Story with Yamada-kun at Lv999, further cementing his status as a reliable screen presence.

The most significant structural shift in his career occurred in February 2025. Following the reorganization of Johnny's Jr. units under STARTO ENTERTAINMENT, Sakuma was announced as a founding member of the new five-member group ACEes. While some sources still reference his tenure with HiHi Jets, the official formation of ACEes marks his current primary affiliation. This move placed him at the forefront of the next generation of STARTO artists. [edit]

Sakuma projects the image of a dedicated, hardworking idol with a clean-cut aesthetic typical of the Johnny's brand. He is known for his energetic stage presence and strong vocal abilities. His public persona is built on reliability and a consistent work ethic, which has earned him respect among fans and peers alike. Social media updates often feature behind-the-scenes content from performances and rehearsals, showcasing his commitment to improving his craft. [edit]

iFANN has not yet collected fame data for this person. As of the August 2026 rankings evaluation, no global fame placement has been recorded for Ryūto Sakuma. The absence of data reflects his status as a rising star within the domestic Japanese market rather than a globally recognized figure.

The fanbase for Sakuma is largely encompassed within the broader HiHi Jets fandom and the newer ACEes fandom. Fans often refer to themselves collectively by the group name rather than using a specific individual moniker for Sakuma alone. Fan campaigns include streaming parties for their songs, birthday celebrations at venues, and support during drama releases. There is no documented evidence of a unique, standalone fandom name exclusively for Sakuma distinct from his groups. [edit]

Sakuma joined Johnny's Jr. at age 10, making him one of the longer-serving juniors in the agency's history by the time of his transition to ACEes in 2025. His initial motivation to join was purely based on being a fan of Arashi, highlighting the deep influence senior idols have on the recruitment process within the agency.

He was temporarily inactive in late 2019 due to health concerns related to stress management, a common occurrence for young idols managing intense schedules. Despite this setback, he returned to activity shortly after and continued to perform without interruption for several years. Fans often note his energetic stage presence and vocal abilities as key traits that distinguish him within the group dynamic. [edit]

Sakuma was raised in Sagamihara, Kanagawa, by his parents. His mother played a pivotal role in launching his career by encouraging him to audition after recognizing his interest in the arts. She cited her own fandom of Arashi as a key factor in her decision to push him toward the entertainment industry. Details regarding other family members or siblings remain private, as Sakuma maintains a strict boundary around his personal life. [edit]
