Rima Nakabayashi

Rima Nakabayashi is a Japanese singer, rapper, and dancer best known as the main rapper of the global girl group NiziU. Born Rima Yokoi in Tokyo, she rose to international prominence through JYP Entertainment's survival show Nizi Project, where her natural flow and charismatic stage presence secured her a spot in the nine-member lineup. She performs under the stage name Rima and serves as the group's primary rapper while also contributing vocals.

Her identity extends beyond just performance; she navigates a public life shaped by her high-profile family background. The daughter of legendary Japanese hip-hop artist Zeebra and former idol Miwa, Rima transitioned from a private upbringing to the spotlight during a period of significant personal change. Her legal surname changed from Yokoi to Nakabayashi following her parents' divorce in late 2020, a move that coincided with her final selection for the group. As of 2026, she remains an active force in the J-pop and K-pop spheres, balancing rigorous training schedules with global promotions. [edit]

Born Rima Yokoi on March 26, 2004, in Tokyo, Japan, she grew up immersed in the music industry without necessarily seeking it out initially. Her father is Ryota Yokoi, widely known by his stage name Zeebra, a titan of the Japanese hip-hop scene. Her mother is Miwa, a former idol who debuted in the 1990s. This unique lineage provided Rima with early exposure to performance arts, yet she maintained a relatively low profile during her childhood compared to the public scrutiny often faced by celebrity offspring.

She attended school in Japan until the age of fifteen or sixteen. In 2020, she made the decisive choice to leave high school to dedicate herself fully to her career aspirations. This decision came at a pivotal moment when her family dynamics were shifting. That same year, her parents announced their divorce after her father was involved in a widely reported scandal involving a resort affair. Following the separation, Rima legally changed her surname from Yokoi to Nakabayashi, adopting her mother's maiden name. These personal upheavals occurred just as she began her journey toward stardom.

Her entry into the entertainment world officially started when she auditioned for Nizi Project, a reality competition launched by JYP Entertainment and YouTube in 2020. The show aimed to form a Japanese girl group with global appeal. Out of thousands of applicants, Rima stood out immediately. Unlike many trainees who had undergone years of formal training, she brought a raw, authentic rap style honed by growing up around her father's work. Her audition tape showcased a confidence that belied her age, catching the attention of judges and viewers alike. She advanced through the rounds, eventually ranking third in the final rankings to secure one of the nine spots in the newly formed group. [edit]

Rima's professional debut arrived in February 2021 when NiziU released their first single, Maze. The track quickly climbed the charts, topping the Billboard Japan Hot 100 and marking a successful start for the new group. Rima took on the role of main rapper, delivering powerful verses that became a signature element of the group's sound. Her ability to switch between rapping and dancing with precision set her apart during live performances.

In the months following her debut, she participated in extensive promotional campaigns for hits like Make You Happy and Step and Step. These releases solidified NiziU's position in both the Japanese and Korean markets. By 2022, she appeared in the documentary NiziU: Clap Clap, offering fans a glimpse into the rigorous training and camaraderie behind the scenes. The group continued to tour internationally, performing in South Korea, the United States, and across Asia.

Her solo contributions have remained tightly woven into the group's output rather than standing alone as separate projects. She has not released a solo studio album but frequently takes center stage during concerts for her rap breakdowns. In 2023, she helped lead the release of Heartris, continuing the group's streak of chart-topping success. By 2024, fan polls consistently ranked her among the most popular members of NiziU, reflecting her strong connection with the audience. In late 2025, she showcased her evolving artistry with the release of VILLAIN, where her rap delivery became even more aggressive and dynamic. As of 2026, she continues to be a central figure in NiziU's activities, maintaining a balance between group obligations and her personal growth as an artist. [edit]

Rima cultivates a cool and confident public image, anchored by her role as the group's main rapper. Her fashion sense often leans towards streetwear and urban styles that complement her rap aesthetic. On social media, she shares glimpses of her daily life, practice sessions, and interactions with fans, presenting a relatable yet professional demeanor.

Media outlets often describe her as a standout member due to her unique background and natural flow. She is perceived as grounded despite her rapid rise to fame. Her ability to handle the pressures of being a child star in a hyper-competitive environment has earned her respect within the industry. Fans appreciate her authenticity and her willingness to embrace her identity as both a performer and the daughter of a hip-hop icon. [edit]

The fanbase surrounding NiziU is highly organized and enthusiastic, though there is no distinct fandom name exclusively for Rima. Fans collectively identify as NiziU supporters, often using hashtags and social media campaigns to boost streaming numbers and promote the group's content. Birthday billboards, subway ads, and charity drives are common ways the community shows support. Rima interacts with these fans through Weverse broadcasts, fan meetings, and her verified Instagram account, where she expresses gratitude for their backing. The dynamic between Rima and her fans is characterized by mutual appreciation for her rap skills and her journey as an idol. [edit]

Rima is often the subject of curiosity regarding her lineage. When she first appeared on Nizi Project, many viewers were unaware that the confident rapper performing complex flows was actually the daughter of hip-hop legend Zeebra. This revelation added a layer of intrigue to her persona, blending her own talent with her famous heritage.

Another notable aspect of her story is the timing of her name change. She legally adopted the surname Nakabayashi in November 2020, shortly before the final episodes of Nizi Project aired. This shift symbolized her resilience and independence as she stepped into the public eye during a turbulent time for her family.

Fans often highlight her stage presence as a defining trait. She is known for her ability to deliver high-energy rap verses while executing synchronized choreography, a skill that requires immense physical stamina. This combination of vocal power and dance precision has become a staple of NiziU's live shows. [edit]

Rima comes from a prominent musical family. Her father is the renowned Japanese rapper Zeebra (real name Ryota Yokoi), and her mother is former idol Miwa (real name Miwa Nakabayashi). She has one biological sister and two half-brothers. Despite her parents' high profiles in the entertainment industry, Rima kept her early life relatively private until her selection for Nizi Project.

The family underwent significant changes in 2020. Her parents divorced later that year following a scandal involving her father. Rima chose to take her mother's maiden name, changing her legal surname from Yokoi to Nakabayashi. She maintains a close relationship with her siblings and currently lives in Japan. While media coverage of her family drama was intense, she has largely focused on her music and avoided discussing personal details in interviews. [edit]

As of 2026, Rima Nakabayashi is single. Like many idols in the J-pop and K-pop industries, she is subject to strict dating policies enforced by her agency, JYP Entertainment. Consequently, no romantic relationships, engagements, or marriages have been officially disclosed or verified by credible sources. While fan speculation occasionally circulates on social media platforms like Twitter and Instagram, none have been substantiated by the artist or her management.

Rima has remained focused on her career since her debut in 2021. She has not publicly dated anyone, and there are no children associated with her. Her personal life remains private, with all attention directed toward her musical achievements and group activities. [edit]

iFANN Editorial Team estimates Rima Nakabayashi's net worth at approximately $350,000 as of 2026. This figure reflects her earnings as a rookie-to-mid-career idol within the J-pop sector. Her income streams are primarily managed through her agency, JYP Entertainment, and include royalties from music sales and digital streaming of NiziU tracks. Concert tours, both domestic and international, provide a significant portion of her revenue, along with brand endorsements secured by the group.

While specific financial records are not public, typical earnings for idols in her tier come from merchandise sales and variety show appearances. There are no public records indicating independent real estate holdings or major investment ventures in her name. The estimated total aligns with the standard compensation structure for active members of successful K-pop and J-pop groups who have been debuting since 2021. [edit]
