Nishimura Riki's dance career began the way many childhood obsessions do: with a DVD. At age three, in Okayama, Japan, he watched Michael Jackson's "Thriller" performance. What followed was not typical toddler imitation. Ni-ki would spend five hours daily recreating Jackson's moves, earning him the nickname "Little Michael Jackson" from family and neighbors who watched the tiny figure moonwalk across the living room.1

His parents—owners of LEAD Entertainment, a dance studio in Okayama—recognized this was not a phase. At age five, Ni-ki formally began training, studying jazz, ballet, hip-hop, contemporary, b-boying, latino, and freestyle. On June 1, 2014, at age eight, he passed the KIDS Audition to train under Kento Mori, a former Michael Jackson backup dancer. At nine, he successfully auditioned for Travis Payne, Michael Jackson's choreographer. The trajectory was clear: Ni-ki was not just talented; he was being groomed by people who had stood beside the King of Pop himself.1

Between 2014 and 2016, Ni-ki's resume accumulated at a dizzying pace. He appeared in a Sony DVD player commercial after passing Kento Mori's commercial audition. In 2015, he performed "Smooth Criminal" at Yokohama Arena as part of a Travis Payne concert. On July 25, 2015, he appeared on FNS 27-hour TV as "Riki Jackson," performing Michael Jackson tributes with his sister Konon. He danced "Billie Jean" and "Slave to the Rhythm" on Japanese television. In 2016, he performed at the Pan Pacific Festival in Oahu, Hawaii, with a Michael Jackson medley and appeared in The Weeknd's "Can't Feel My Face" Japanese music video.1

But the most significant performance came in 2016, when Ni-ki joined a group called SHINee Kids. It would redirect his entire future.

In 2016 and 2017, Ni-ki became a member of SHINee Kids, a dance group covering SHINee choreography. He specifically covered Key's parts, studying the idol's movements with the same intensity he had once applied to Michael Jackson. Then came the opportunity that would alter his path: at age 11, Ni-ki was selected as a backup dancer for SHINee's "SHINee World 2017 ~FIVE~ Special Edition" concert at the Tokyo Dome.2

Standing on that stage, surrounded by 55,000 fans, Ni-ki wrote a letter to Key that revealed the shift happening inside him: "I want to be a person who makes many people happy and smile on stage at Tokyo Dome like Key someday. Key-kun is my hero!!" The experience was transformative. Michael Jackson had been his first idol, but Key—present, alive, and performing in front of him—became something more tangible: a roadmap. Ni-ki decided he wanted to become a K-pop idol.2

In 2018, at age 12, Ni-ki auditioned at the BigHit Global Audition during the K-POP COVER DANCE FESTIVAL, performing Taemin's "Sayonara Hitori." He was not selected. But a year later, in 2019, he re-auditioned in South Korea, this time performing BTS Jimin's "Lie." At age 13, he successfully joined Belift Lab. The training period would be the shortest among all future ENHYPEN members: eight months. He moved to South Korea alone, leaving his family and the Michael Jackson tributes behind, to chase the dream that began at the Tokyo Dome.3

When I-LAND premiered on June 26, 2020, Ni-ki was 14 years old—the youngest contestant. The producers named him the best dancer on the show. BTS's J-Hope, SEVENTEEN's The8, and Big Hit choreographer Son Sungdeuk all praised his exceptional body control and artistic expression. In Episode 1, he performed SuperM's "Jopping" with Hanbin and Nicholas, demonstrating the fluidity and power that had been honed since age three.4

But I-LAND was not just about talent; it was about resilience under elimination pressure. At one point, Ni-ki was sent to the "GROUND"—the zone for contestants at risk of elimination. The emotional crisis hit hard. He lost his position as dance representative, a title that had defined him since childhood. He held back tears until producers consoled him. The vulnerability was jarring for someone so young, so far from home, and so singularly focused on dance. Yet he pushed through, developing significantly during the show and impressing judges with his rapid improvement.4

On September 18, 2020, the finale arrived. The first six members were chosen by global vote. Ni-ki ranked fourth with 1,140,728 votes. The seventh member, Sunoo—who had become Ni-ki's first friend during the show—was selected by the producers' choice. On November 30, 2020, ENHYPEN officially debuted with "Border: Day One." Ni-ki was 14 years old, the maknae of a group that would soon redefine 4th-generation K-pop.4

As ENHYPEN evolved, so did Ni-ki's role. He became the group's unofficial choreography team leader, regularly providing input and teaching members their parts. His ability to memorize entire choreographies in 10-20 minutes became legendary within the company. But his most defining choreographic contribution came in May 2023, during the MANIFESTO tour stop in Manila.5

In a hotel room, Ni-ki listened to the demo for "Bite Me," the lead single from the upcoming "Dark Blood" album. Alone with the track, he began creating choreography, incorporating a trendy hook movement that would become the song's visual signature. The choreography was eventually used for the official release. The album debuted at number 4 on the Billboard 200, sold 1,108,337 copies on its first day, and "Bite Me" reached number 35 on the global Spotify chart—the group's highest peak at the time.5

Ni-ki's philosophy on performance has remained consistent: "A song's message should always be reflected through facial expressions and movements." He emphasizes head movement for dynamic, energetic performances and values ad-libbing moments, describing them as "so amazing that they make me think I was born to do this." Yet despite industry recognition and fan acclaim, he has never been satisfied. "There's never been a performance that I was 100% satisfied with," he told Weverse Magazine. The pursuit of perfection—instilled at age three with "Thriller"—has never left him.1

In May 2024, Ni-ki was selected as Studio Choom's Artist of the Month, performing "Trendsetter" by Connor Price and Haviah Mighty, followed by Kendrick Lamar's "HUMBLE." Choreographed by Yumeki and The Bips (Bico Lim, Taehoon Kim, and Woowon), the performance garnered 1,745,633 views in the first 24 hours, making it the 5th most-viewed AOTM. The recognition cemented his status as a 4th-generation dance prodigy.6

Two months earlier, at Coachella 2025, Ni-ki contributed choreography ideas to the "ParadoXXX Invasion" dance break, leading 12 local dancers in a dance battle segment. The hashtag #ENCHELLA trended worldwide, and ENHYPEN became the K-pop boy group with the shortest time between debut and performing at the festival. Ni-ki's journey from Okayama dance studios to Coachella's main stage had taken just over four years.7

But perhaps the most emotional full-circle moment came on December 31, 2024, when Ni-ki performed "Guilty" with Taemin at MBC Gayo Daejejeon. Taemin—the same artist whose "Sayonara Hitori" Ni-ki had performed for his first failed audition in 2018—now stood beside him as a peer. Ni-ki described the collaboration as a "dream come true." It was the second reunion with his SHINee idols; in June 2023, he had filmed a dance challenge with Key for "Hard."8

The boy who wrote a letter to Key at age 11, declaring him a hero, had become an artist in his own right. He had stood on stages around the world, choreographed for millions, and collaborated with the idols who inspired him. Yet when asked about his goals, Ni-ki's answer remained unchanged: "I want to show everyone I can keep growing." The five-year-old who spent hours imitating Michael Jackson is still chasing perfection, still searching for the 100% satisfaction that has always eluded him.1
