Tomiyasu Yu (NEXZ) Profile 2026: Bio, Age & Interesting Facts
Tomiyasu Yu, known professionally as YU, is a Japanese singer and dancer and a member of NEXZ, the seven-member boy group created through JYP Entertainment and Sony Music’s Nizi Project Season 2. Born on April 27, 2005, Yu is 21 in 2026 and is currently the oldest member of NEXZ. Secondary K-pop profile databases identify his group roles as dancer, vocalist and visual, while the official NEXZ profile confirms his name and birth date but does not publish individual positions.
Yu finished fifth in the final ranking of Nizi Project Season 2, securing his place in NEXZ. The group released the pre-debut song “Miracle” in December 2023 and officially made its global/Korean debut with “Ride the Vibe” on May 20, 2024. Since then, NEXZ has expanded its Korean and Japanese discography, completed its first national tour in Japan, entered larger concert venues, collected rookie awards, and moved into a more international performance schedule.
For Yu, 2026 has been a particularly active year. NEXZ released “Mmchk” in April, its Japanese EP “Hellmate” in June, and its fourth Korean mini album “SAUCIN’” in August. The group’s latest official notices also show the September release of the “UPGRADE” music video, while its first Asia tour, “SAUCIN’ THE WORLD,” has been announced with Seoul concerts scheduled for October 17 and 18. Yu also performed with NEXZ at Rock in Rio in Brazil on September 11, 2026.

Who Is Tomiyasu Yu?
Yu, whose full name is Tomiyasu Yu (富安 悠), is one of the seven members of NEXZ. He was born on April 27, 2005, and is the group’s oldest member by birth date. KProfiles and Kpopping list his roles as dancer and vocalist, with KProfiles additionally listing him as a visual. These are secondary-source position labels rather than fields currently displayed on NEXZ’s official profile page.
Yu first became known to a wider audience through Nizi Project Season 2. The competition eventually selected seven finalists for NEXZ, with Yu finishing in fifth place. His route to the final group followed multiple audition stages and performance evaluations, making his fifth-place finish the decisive point that led to his debut.
KProfiles records that Yu had previous audition experience before entering Nizi Project Season 2. The same profile also lists cooking, gaming, making sweets and skateboarding among his interests, and says he had been breakdancing for nine years as of 2024. Because these details come from secondary profile material rather than the current official NEXZ biography, they should be treated as profile information rather than core agency-confirmed statistics.
His group career began with “Ride the Vibe” in May 2024. NEXZ then released its first Japanese EP in August, followed by “NALLINA,” “O-RLY?,” “Beat-Boxer,” “Mmchk” and “SAUCIN’.” The group’s official history also records major live milestones, including a sold-out 2024 Japanese showcase tour, a 15-city 2025 tour, its first arena tour in 2026, and the newly announced Asia tour.
NEXZ Group History
Formation Through Nizi Project Season 2
NEXZ originated from Nizi Project Season 2, a JYP Entertainment and Sony Music-related audition project designed to create a global boy group. Sony Music’s official announcement said the audition process ran from regional auditions to training camps in Japan and Korea, with more than 10,000 applicants taking part.
The final seven members were Tomoya, Haru, Yuki, So Geon, Yu, Hyui and Seita. Yu finished fifth. The group’s name, NEXZ, is explained by the official Japanese site as representing “Next Z(G)eneration.” The N and Z also connect the group to the Nizi Project and its next-generation concept.
Pre-debut: “Miracle”
Before the formal debut, the newly selected members released “Miracle” on December 18, 2023. The song had been performed at the Nizi Project Season 2 final stage and was issued as a pre-release track in both the group’s Korean and Japanese activities.
That release gave audiences an early look at the seven-member team before the official debut campaign.
Official Debut With “Ride the Vibe”
NEXZ made its official global/Korean debut on May 20, 2024, releasing its first single album “Ride the Vibe.” JYP’s official discography describes the release as the group’s debut and presents the title track as the first major introduction to NEXZ’s musical identity.
The group’s Japanese official profile records two early milestones: “Ride the Vibe” reached No. 1 on Hanteo’s daily Physical Album Chart, while the music video passed 10 million YouTube views within three days according to the agency’s profile.
Japanese Debut
NEXZ followed its Korean/global debut with its Japanese debut on August 21, 2024, releasing Japan 1st EP “Ride the Vibe (Japanese Ver.) / Keep on Moving.” The official Japanese profile says the release reached No. 1 on the Oricon daily album chart.
The group also held its first Japanese showcase tour in August 2024. The official profile records three cities and six shows, all sold out, with an attendance figure of about 40,000.
NALLINA and the First Expansion Phase
NEXZ released its first mini album, “NALLINA,” on November 18, 2024. JYP presented the project around a bold, free-spirited identity, with the title track produced with contributions from J.Y. Park and other writers.
For Yu, this period was important because NEXZ was moving from an audition-created rookie act into a group developing a recognizable catalog and stage identity.
2025: O-RLY?, One Bite and Beat-Boxer
The group’s second mini album, “O-RLY?”, arrived on April 28, 2025. NEXZ’s official Japanese profile says the release reached weekly No. 1 positions on both Hanteo’s World Chart and Physical Album Chart, while Circle Chart also recorded weekly No. 1 placements on its Album and Retail Album charts.
NEXZ then released its Japanese second EP “One Bite” on July 16, 2025. The release debuted at No. 1 on Billboard Japan’s weekly Top Albums Sales chart, according to the group’s official Japanese profile.
The group also launched its first national tour, NEXZ LIVE TOUR 2025 “One Bite,” covering 15 cities and 18 performances and drawing more than 50,000 attendees according to the official Japanese profile. The tour included a performance at Nippon Budokan.
NEXZ released its third Korean mini album, “Beat-Boxer,” on October 27, 2025.
2026: Mmchk, Hellmate and SAUCIN’
NEXZ opened its 2026 Korean comeback cycle with “Mmchk” on April 27. JYP described it as a release built around the group’s so-called “NEXZ Way,” with members participating in lyric writing. The agency also reported that “Mmchk” reached the top of the Bugs real-time chart, set a first-week career high and earned NEXZ its first-ever music-show win on MBC M’s Show Champion on May 6.
The Japanese side of the group’s 2026 schedule included its first arena tour, NEXZ LIVE TOUR 2026 “Hellmate,” with two Tokyo shows at Yoyogi National Stadium First Gymnasium on May 30–31 and two Osaka shows at Osaka-jō Hall on June 12–13.
NEXZ released the Japanese third EP “Hellmate” on June 24, 2026. The EP contains “Hellmate,” “Hands up, Yo!,” “Can’t hide” and “Mmchk (Japanese Ver.).”
Its fourth Korean mini album, “SAUCIN’,” arrived on August 24, 2026. The six-track project includes “LOCO,” “SAUCIN’,” “APPETITE,” “UPGRADE,” “20 NOW” and “ALIENS,” with “SAUCIN’” as the title track.
The group’s official notices show that an “UPGRADE” music video was released on September 8, 2026.
Tomiyasu Yu Profile
Personal Information
| Detail | Information |
|---|---|
| Stage Name | YU / Yu |
| Full Name | Tomiyasu Yu |
| Japanese Name | 富安 悠 |
| Korean Stage Name | 유우 |
| Date of Birth | April 27, 2005 |
| Age | 21 as of September 20, 2026 |
| Zodiac Sign | Taurus |
| Chinese Zodiac | Rooster |
| Birthplace | Fukuoka, Japan; some secondary databases specify Kurume City |
| Nationality | Japanese |
| Height | Not publicly verified |
| Weight | Not publicly verified |
| Blood Type | O, according to KProfiles/Kpopping |
| MBTI | ESFP in current secondary profiles; earlier listing was ENTJ |
| Group | NEXZ |
| Nizi Project Ranking | 5th |
Yu’s birth date is directly listed by NEXZ’s official Japanese website. KProfiles and Kpopping additionally list his nationality, blood type and MBTI. Because those personal-profile fields are not displayed on the current official NEXZ biography, they are best treated as secondary-source information. KProfiles specifically notes that Yu’s MBTI was previously listed as ENTJ before being updated to ESFP.
His height and weight are not publicly verified in the sources reviewed. It is better not to insert numbers frequently repeated by profile sites without a reliable primary source.
Group Role
KProfiles and Kpopping identify Yu as a dancer and vocalist, with KProfiles also listing him as a visual. These databases agree broadly on his performance roles, although the current official NEXZ profile does not display formal individual position labels.
Being NEXZ’s oldest member also gives Yu a distinctive place in the lineup. He is older than Tomoya, who was born in January 2006, and is therefore the oldest of the seven by birth date.
Early Life and Performance Background
Yu was born in Fukuoka, Japan. KProfiles records that he had audition experience before entering Nizi Project Season 2 and that he had a longstanding interest in performance. The profile also says he had been breakdancing for nine years as of 2024.
During Nizi Project Season 2, Yu had to develop across both vocal and dance evaluations. KProfiles’ contestant record documents several of his selected performance songs, including JUNHO’s “Your Voice” for a vocal performance, Stray Kids’ “God’s Menu” in a dance evaluation, and later performances connected to GOT7, Rain and 2PM during the competition.
Education information is often repeated across profile and fan sites, but the current official NEXZ sources reviewed for this article do not provide a verified education biography. This information is not publicly available from the primary sources reviewed.
Nizi Project Season 2 Journey
Yu’s final result was 5th place. That ranking was enough to secure a place in NEXZ’s debut lineup.
The Nizi Project record shows that his ranking varied significantly during the competition. He placed first in the individual-level ranking for one stage in Korea, while other evaluations placed him lower. That pattern is useful context: his final debut was the result of performance across the full competition rather than one isolated ranking.
His trajectory also illustrates the purpose of the project itself. NEXZ was not simply assembled from already-established idols; its members were selected through multiple rounds intended to assess singing, dancing, stage presence, attitude and adaptability. Yu emerged from that process as the fifth-ranked finalist.
Career After Debut
Yu debuted with NEXZ on May 20, 2024, on “Ride the Vibe.” Since then he has remained part of the group’s seven-member lineup across Korean releases, Japanese releases, concerts and international appearances.
An interesting part of Yu’s 2025–26 stage history is that the official Japanese Blu-ray for NEXZ LIVE TOUR 2025 “One Bite” in Nippon Budokan includes Yu’s solo-angle selections for “Simmer (Japanese Ver.)” and “One Bite.” This is not a solo release; it is concert footage focused on his individual stage perspective.
In May 2026, JYP announced that Yu could not attend the May 17 “Mmchk Special Japan Fan Sign Event” because an unexpected administrative issue caused difficulties with entry procedures. The agency said the event would proceed with the other six members. This was described as an event-specific situation rather than a lineup change.
Later in 2026, Yu continued appearing as part of NEXZ’s public group activities. NEXZ performed at Rock in Rio in Brazil on September 11, 2026, with Brazilian coverage naming all seven members, including Yu.
Family Background

Relationship Status
There is no publicly confirmed relationship information for Yu in the authoritative sources reviewed.
Rumors, fan theories, shipping content and anonymous social-media claims have not been included.
Net Worth
Yu’s exact net worth is not publicly available.
There is no reliable audited figure or official financial disclosure that would justify presenting a specific number as fact. Online “net worth” estimates should therefore not be treated as verified.
Official Social Media
No verified personal social-media account for Yu was identified in the official sources reviewed. NEXZ itself operates the following verified group channels:
| Platform | Official Account |

Tours and Concerts
NEXZ SHOWCASE 2024 “Ride the Vibe”
NEXZ’s first Japanese showcase tour took place in August 2024. The official Japanese profile records three cities, six performances and approximately 40,000 attendees, with all shows sold out.
NEXZ LIVE TOUR 2025 “One Bite”
The group’s first nationwide Japanese tour covered 15 cities and 18 performances and drew more than 50,000 people. The schedule included Nippon Budokan, marking a major venue milestone for the group.
NEXZ LIVE TOUR 2026 “Hellmate”
The 2026 tour was NEXZ’s first arena tour, with performances at:
- May 30, 2026 – Yoyogi National Stadium First Gymnasium, Tokyo
- May 31, 2026 – Yoyogi National Stadium First Gymnasium, Tokyo
- June 12, 2026 – Osaka-jō Hall, Osaka
- June 13, 2026 – Osaka-jō Hall, Osaka
The official tour page confirms all four dates.
NEXZ 1ST ASIA TOUR “SAUCIN’ THE WORLD”
On September 8, 2026, NEXZ announced its first Asia tour. As of September 20, the publicly announced opening dates are:
- October 17, 2026 – Olympic Hall, Seoul
- October 18, 2026 – Olympic Hall, Seoul
Soompi reported that additional Asia dates would follow, while JYP’s official notice lists the Seoul tour announcement and ticket information.
2026 International Activity
NEXZ’s international schedule expanded beyond Japan and Korea during September 2026. The group performed at Rock in Rio in Brazil on September 11, appearing on the festival’s Palco Mundo lineup. Rock in Rio’s official site lists NEXZ among the day’s performers, and Brazilian broadcaster Gshow reported that all seven members, including Yu, performed.
This is a notable part of Yu’s 2026 profile because it places him in one of NEXZ’s largest public international festival appearances to date.
Brand Endorsements and Partnerships
One of NEXZ’s clearest documented commercial partnerships is Aquarius, the Coca-Cola Japan sports-drink brand.
In May 2024, Aquarius announced NEXZ’s first television commercial, featuring the members in training and performance settings. The campaign used “Keep on Moving,” a J.Y. Park-written and produced song created around Aquarius’s brand message.
This should be described as a group advertising campaign rather than an individual Yu ambassador appointment.
