What is Ni-Ki’s real name?
Full Name and Stage Name
- Ni-Ki’s real name is Nishimura Riki (Famous Birthdays).
- His stage name is a shortened, adapted version of his birth name.
Nationality and Hometown
- Ni-Ki is Japanese, born in Okayama, Japan (Kpop Profiles).
- He is the only Japanese member of ENHYPEN (Seat Unique (ticketing and blog platform)).
The implication: Ni-Ki’s identity is rooted in his Japanese heritage, but his stage name has become a global brand.
Can Ni-Ki speak fluent English?
Language Abilities
- Ni-Ki speaks English as a foreign language. He can understand and speak basic English, but is not fluent (Kpop Profiles).
- He often communicates in Korean and Japanese with members.
Communication in English
- In interviews and fan interactions, Ni-Ki uses simple English phrases and relies on translation when needed.
The catch: fluency is a matter of definition; his understanding outpaces his speaking, a common profile for idols who train in Korea.
How old will Ni-Ki be in 2026?
Age Progression

Body Stat Overview

- Waist size: not officially disclosed; estimated 28–30 inches based on fan measurements.
Ni-Ki’s height is a point of contention among fans: 183 cm vs. 186 cm. The discrepancy likely stems from different measurement methods (shoes, posture, or self-reported vs. official). For a main dancer, either height supports his dynamic stage presence.
The trade-off: two different published heights mean fans should check the source’s authority before taking a number as fact.

“Ni-Ki is the most naturally talented dancer in our group.”
