Hyui (NEXZ) Profile 2026: Age, Bio, Birthday & Interesting Facts
Hyui has spent much of his teenage years inside the JYP Entertainment training system, but his journey into NEXZ began before the group officially existed. Known during Nizi Project Season 2 as Yuhi, he became one of the seven contestants selected to debut in NEXZ after finishing sixth in the final ranking.
Born on May 11, 2007, in Wakayama, Japan, Hyui is 19 years old as of September 21, 2026. He officially debuted with NEXZ on May 20, 2024, and has since developed into a member associated with rap, vocals, songwriting and performance.
What makes Hyui’s story particularly interesting is the amount of preparation behind his relatively young career. Before NEXZ‘s debut, he spent years training in Korea and went through the demanding stages of Nizi Project Season 2. His public interviews also reveal interests away from the stage, including music, food, fashion, fitness and creative work.

Who Is Hyui From NEXZ?
Hyui is a Japanese member of the seven-member group NEXZ, a global boy group created through the JYP Entertainment and Sony Music collaboration behind Nizi Project Season 2.
His birth name is Komori Yuhi, written in Japanese as 小森優陽. He participated in the audition program under the name Yuhi, while Hyui became his official stage name for NEXZ activities. ORICON’s original Nizi Project profile lists him as Yuhi and identifies his birthplace as Wakayama Prefecture.
NEXZ’s current official profile lists Hyui alongside Tomoya, Yu, Haru, So Geon, Seita and Yuki. JYP’s official NEXZ website also lists Hyui as one of the group’s seven members.
Hyui Age in 2026
Hyui was born on May 11, 2007. He turned 19 years old on May 11, 2026. NEXZ’s official Japanese website gives the same birth date, while its 2026 birthday announcement explicitly celebrated Hyui’s 19th birthday.
For readers checking his age at different points in the year, Hyui is 18 before May 11, 2026, and 19 from May 11 onward.
Hyui Birthday
Hyui’s birthday is May 11, 2007.
His birthday is officially documented by NEXZ’s website and was also included in his original Nizi Project profile. His 19th birthday was officially celebrated through NEXZ’s fan-club content in May 2026.
Hyui Real Name
Hyui’s birth name is Komori Yuhi (小森優陽).
During Nizi Project Season 2, he was publicly introduced as YUHI. After NEXZ was formed, the group’s official activities adopted the stage name HYUI. This is why older Nizi Project clips and newer NEXZ content can appear under different romanizations even though they refer to the same person.
Where Is Hyui From?
Hyui is from Wakayama Prefecture, Japan. His birthplace was included in the official-style contestant information published around Nizi Project Season 2 and has also been repeated in later Japanese entertainment profiles.
He eventually moved to Korea for training and spent a substantial part of his teenage years there. In a 2025 interview with The Korea Times, Hyui said he had lived in Korea for around six years at that point and described realizing that he had adapted when he began responding naturally in Korean during conversations.
That period of living and training in Korea is an important part of understanding his development as a performer.
Hyui Before NEXZ
Hyui’s path to NEXZ started well before the group’s official debut.
According to his Nizi Project profile, he was a JYP Entertainment trainee and entered Nizi Project Season 2 as one of the contestants competing for a place in the new group. ORICON records his Part 1 overall ranking as sixth, with seventh-place rankings in both dance and vocal evaluations. During Part 2 in Korea, he placed fourth in the individual level test, third in the team battle and third in the team performance ranking.
His final ranking was especially important because only seven contestants were selected for NEXZ. Hyui finished sixth, earning a place in the final lineup.
Hyui’s Nizi Project Season 2 Journey
Nizi Project Season 2 was the audition project that ultimately produced NEXZ. More than 10,000 applicants participated in the overall audition process, with contestants progressing through regional auditions, training and evaluation stages before the final lineup was chosen.
Hyui’s original profile gives a useful snapshot of his progress. Although his Part 1 dance and vocal rankings were both seventh, his Part 2 results improved noticeably, including a fourth-place finish in his individual level test and third-place finishes in the following two team stages.
That progression became part of his story before debut: instead of arriving in the final lineup as the top-ranked contestant, he earned his position through steady improvement across the competition.
Hyui’s Final Ranking
Hyui finished 6th place in the Nizi Project Season 2 final ranking.
The seven final contestants were selected to become NEXZ, with Hyui joining Tomoya, Haru, Yuki, So Geon, Yu and Seita. His final-stage appearance therefore directly led to his professional debut with the group.
What Did Hyui Say After Making NEXZ?
After his selection, Hyui expressed gratitude toward his family for supporting his move to Korea and toward the other contestants who had worked alongside him.
The comment is significant because it reflects how early his professional training began and how much of his formative experience happened alongside the other Nizi Project contestants.
When Did Hyui Debut?
Hyui officially debuted as a member of NEXZ on May 20, 2024, with the group’s Korean debut single album Ride the Vibe.
NEXZ had previously released the pre-debut song “Miracle” on December 18, 2023, using a song performed at the final stage of Nizi Project Season 2. The group’s official history identifies May 20, 2024, as its global debut date.
Hyui’s Role in NEXZ
NEXZ has not consistently presented a traditional fixed-position system on its main official profile, but reputable Japanese coverage describes Hyui as an all-rounder involved in rap, vocals and songwriting. nicola specifically identifies him with rap, vocals and songwriting, while recent interviews show Hyui discussing both rap and vocals as important parts of his performance identity.
This broader musical role is worth noting because Hyui himself has spoken about wanting audiences to recognize that NEXZ is not only a performance-focused group.
In a 2025 Korea Times interview, he said he wanted people to see strength in the group’s vocals and rap, as well as its performance.
Hyui and Songwriting
Songwriting is one of the recurring creative interests associated with Hyui.
His original ORICON profile listed composition among the things he likes, alongside listening to music, sports, impersonations and spending time in nature. Later nicola profiles also describe him as involved in songwriting.
His comments in recent NEXZ interviews also show that the members have been taking a more active role in developing their music and performances. Hyui’s interest in songwriting therefore fits into the group’s wider shift toward greater creative involvement.
Hyui’s Musical Personality
Hyui has described music as an important part of his identity beyond simply performing songs written by others.
His stated ambition during Nizi Project was to become an artist who could give people energy and courage through his music.
Years later, his interviews continue to connect music with communication. In a 2026 nicola interview, Hyui explained that performing lets him communicate with fans through music and performance, while magazine interviews gave him another way to express his thoughts through words.
Hyui Speaks Korean Fluently
Hyui’s time in Korea has clearly influenced his language skills.
Speaking to The Korea Times in October 2025, Hyui said that he had been living in Korea for about six years and recognized his growing fluency when Korean conversation began to feel natural.
This is especially relevant to NEXZ because the group operates between Korean and Japanese entertainment markets. Hyui has also discussed the challenge of performing and communicating across those different environments.

Hyui and Yuki: NEXZ’s Youngest Pair
Hyui and Yuki are the two youngest members of NEXZ.
Their friendship began during the Nizi Project period and has continued through NEXZ’s career. Japanese magazine nicola has regularly featured them together, describing them as the group’s youngest duo.
Their interviews also reveal a comfortable friendship. In one nicola feature, Yuki described Hyui as calm and mature while also saying that Hyui enjoys joking around with members and friends.
What Is Hyui Like Off Stage?
Public interviews suggest a quieter and more thoughtful side to Hyui than his stage performances sometimes indicate.
In a 2025 nicola interview looking back at his 14-year-old self, Hyui said that he used to think too heavily about his worries and later learned to approach things more lightly. He also encouraged teenagers to spend time enjoying the things they genuinely like.
His comments do not establish a complete picture of his private personality, but they do provide a glimpse into how he thinks about growth and pressure.
Hyui’s Favorite Dessert
One of Hyui’s more memorable food preferences surfaced during a 2026 nicola interview.
He said that his favorite dessert is Mont Blanc, a chestnut-based dessert. Hyui explained that he had asked for Mont Blanc for his birthday when he was younger and had continued liking it over the years.
For chocolate, he said he prefers milk chocolate, while also enjoying chocolate mixed with strawberries.
Hyui’s Favorite Korean Food
Hyui has also talked about his love of spicy Korean food.
In nicola‘s Korean-culture feature, he said tteokbokki was one of his favorite Korean foods. He described visiting a tteokbokki restaurant where he could choose the spice level and recommended adding cheese for people who find the heat difficult.
His comments in The Korea Times also show that Korean food became part of his life during his long period of living and training in the country.
Hyui’s Fashion Style
Hyui has shared a surprisingly clear picture of his personal fashion preferences.
In a 2025 nicola feature, he said that he likes wearing shirts and had purchased a light-blue oversized shirt for spring and summer. He specifically liked the loose fit and wanted to wear it in a relaxed way.
Later that year, he described another side of his style: low-top sneakers, shorts and longer socks, often with black sneakers and white socks. He also said that he wanted to explore a hip-hop street look and liked the idea of wearing a large hoodie over a cap.
These are useful examples of Hyui’s publicly discussed style, but they do not establish any permanent brand endorsement or exclusive fashion partnership.
Hyui’s Skincare and Beauty Habits
Hyui has spoken publicly about one aspect of his approach to skin care: nutrition.
In an August 2025 nicola interview, he said he believed getting enough nutrition was important for healthy skin and that he generally tried to eat salad. He also mentioned taking a multivitamin supplement before going to bed.
This should be presented as Hyui’s own publicly stated habit, not as professional medical or dermatological advice.
There is no reliable public source establishing a complete branded skincare routine for Hyui, so claims about specific cleansers, serums or luxury beauty products should not be added without a direct source.
Hyui’s Room and Dorm Life
Hyui has also shared a small but interesting detail about his living arrangement.
In March 2026, he told nicola that he shared a room with Seita in the group’s Korean dorm. He said the two had been discussing redecorating their room because other members had already changed their spaces. Hyui wanted to add a large storage case and replace the bed.
This is a rare public glimpse into his everyday living environment, but it should not be expanded into private housing details that Hyui has not disclosed.
Hyui’s Interests and Hobbies
Hyui’s publicly listed interests include listening to music, sports, impersonations, composing music and spending time in nature. These preferences were included in his original Nizi Project profile.
He has also discussed food, fashion and other everyday interests in his nicola series, giving fans a broader look at his personality away from performances.
Rather than attaching an overly broad list of “favorite things” to his profile, it is safer to stick to interests Hyui has actually discussed publicly.

NEXZ then released its second single album Mmchk on April 27. The group’s official profile says the song earned NEXZ its first No. 1 on Show Champion and that shipment figures reached a new career high.
The group followed that with the first arena tour, NEXZ LIVE TOUR 2026 “Hellmate,” in Tokyo and Osaka, and released its third Japanese EP Hellmate on June 24.
Most recently, NEXZ released its fourth mini album, SAUCIN’, on August 24, 2026. The official site describes the project as the group’s latest work built around adding its own distinctive “sauce” to different songs.
Hyui and NEXZ’s 2026 Global Activities
Hyui’s 2026 schedule has also extended beyond Japan and Korea.
In August 2026, Bandwagon interviewed NEXZ following the group’s Singapore show during its global showcase. Hyui reflected on visiting different places and meeting NEX2Y, saying that performing for fans gives the members energy and happiness.
The interview came shortly after NEXZ’s first Japan arena tour and during a period when the group was increasing its activity across Asia.

Hyui’s appeal is not based on one single role.
His background includes years of training, a competitive Nizi Project journey, rap and vocal performance, songwriting interests and experience working in both Japanese and Korean entertainment environments.
