Niki ENHYPEN: Profile, Age, Height, and Facts (2025)

There’s a reason why the youngest member of a K-pop group often captures the most curiosity. Niki (Ni-Ki) of ENHYPEN, born Nishimura Riki on December 9, 2005, fits that pattern perfectly — a Japanese teenager who went from a trainee in Okayama to the main dancer and maknae of one of the fastest-rising fourth-generation groups. This profile walks through his verified stats, the story behind his stage name, and the open questions fans still ask about his family and the group’s stability.

Birth name: Nishimura Riki ·
Date of birth: December 9, 2005 ·
Age (2025): 19 (international) / 21 (Korean) ·
Height: 179 cm (5’10.5″) ·
Nationality: Japanese ·
Group: ENHYPEN

The implication: seven key facts converge on a consistent biographical core, while height and family specifics show notable variation across sources.

How old is Ni-Ki in Korean?

Ni-Ki’s international age as of 2025 is 19 — he was born on December 9, 2005 in Okayama, Japan (Famous Birthdays). In the Korean age system, which counts the time in the womb as one year and adds a year on New Year’s Day, he is 21. His height is most commonly listed at 179 cm (Kpop Profiles), though some fan sites claim 183 cm (Kpop Profiles) and even 186 cm (ENHYPEN Guide).

The pattern: age and height are the most contested stats in fan profiles, but the core data — a late-2005 birthdate and a height around 179–183 cm — is consistent across the most reliable sources.

Why is Ni-Ki called Riki?

His full Japanese name is Nishimura Riki. “Ni-Ki” is a stylized romanization of “Riki,” chosen as his stage name during I-LAND (Wikipedia). The name “Riki” itself means “strength” or “power” in Japanese, fitting his reputation as a powerful dancer. According to Kpopping, the stage name was officially adopted in mid-2020 when he was introduced as a contestant.

What this means: the name confusion is simply a transliteration choice — fans who call him “Riki” are using his given name, while “Ni-Ki” is the official stage version.

What does Niki love?

Ni-Ki has shared several personal interests in interviews and fan content. He started dancing at age 3 and trained in jazz and ballet (Famous Birthdays). He also grew up playing soccer. His hobbies include watching movies, eating meat (especially beef), and collecting sneakers (Kpop Profiles). His favorite color is black, and his MBTI has been listed as INTJ, though it may have changed over time (Kpop Profiles). He is left-handed and can play the piano (Kpop Profiles).

The pattern: Ni-Ki’s interests revolve around movement and visual aesthetics — dance, fashion, and collecting — which align with his role as the group’s main dancer.

Is Ni-ki ENHYPEN from a rich family?

This is one of the most persistent fan questions, but there is no verified information about his family’s wealth. He has two older sisters (Famous Birthdays), and Kpop Profiles mentions parents and sisters without financial details. Ni-Ki has never publicly disclosed his family’s economic background, and Belift Lab has not issued any statement on the matter. Rumors of a wealthy family likely stem from his early training in dance and music, but that alone is not evidence.

The catch: without an official source from the agency or a credible financial disclosure, any claim about family wealth remains speculation.

Is ENHYPEN losing a member?

In 2024, rumors circulated that HEESEUNG would leave ENHYPEN. Both Kpopping and Wikipedia note that Belift Lab and HEESEUNG released statements denying the exit. As of 2025, all seven members — HEESEUNG, JAY, JAKE, SUNGHOON, SUNOO, JUNGWON, and NI-KI — remain active and have continued with group activities including tours and album releases.

Why this matters: fan anxiety about member changes is common in K-pop, but in this case the agency and the member himself have publicly confirmed the group’s stability.

The pattern: the consensus height of 179 cm is the most cited, while alternative numbers from fan sources introduce a ±7 cm range that reflects the lack of an official Belift Lab profile.

Confirmed facts vs. what’s unclear

“Ni-Ki, as the youngest member of ENHYPEN, continues to impress audiences with his dance skills and stage presence.”

News1 interview (via X fan translation, 2025)

“We clarify that HEESEUNG will not be leaving ENHYPEN, and all seven members will continue their activities as a team.”

Belift Lab statement (reported by Kpopping, 2024)

For the growing international fanbase invested in ENHYPEN’s lineup, the 2024 denial from Belift Lab provided a clear answer: the group remains intact. For Japanese fans watching Ni-Ki’s trajectory, the next question is whether he will pursue solo work in Japan or continue focusing on group promotions. The catch: the choice is between expanding his individual brand in his home market or deepening his role within the group’s global push.
