JISOO
A Korean vocalist who crossed into a Japanese audition because staying where she was had stopped working. Her voice is deep, clear, and stubborn enough to make her rerecord a guide vocal nobody else thought needed fixing.
The music started in the car
JISOO grew up in Incheon as an only child. Her parents taught her to finish what she started, which apparently lodged itself deep enough that years later a producer could say a recording was good and JISOO would still ask for another take.
Her mother loved music and played overseas hip-hop and R&B in the car instead of children’s songs. JISOO has called those rides an origin point. The detail explains more than a generic “she loved singing from a young age” sentence. Her lower register, phrasing, and taste did not appear from nowhere after HANA formed.
During high-school career counseling, she realized that she would not be happy unless she pursued music. That decision was not followed by an easy debut. It led into years of training, doubt, a period when she considered quitting, and eventually a move into an audition conducted mostly in a language she had taught herself.
Two years inside the Korean trainee system
JISOO began agency training at seventeen and trained for roughly two years. Profiles and Japanese reporting have connected that period to YG Entertainment, although the most reliable interviews often describe it more cautiously as training at a Korean entertainment company. The important part is confirmed: she experienced the Korean idol system before No No Girls.
She did not debut during that first run. By 2023 her mental health had dropped badly enough that she questioned whether music was still possible. She later said the Korean basketball webtoon Garbage Time helped pull her through. Wanting to read the next episode gave her one small reason to keep moving. She brought the complete set to Japan during No No Girls, then read, cried, practiced, cried again, and went back to work.
No No Girls: leaving Korea to find a different answer
JISOO applied to BMSG and CHANMINA’s No No Girls after thinking that another country might let her discover a version of herself she could not reach at home. She studied Japanese on her own before applying. The audition’s premise mattered to her history because it was built around women who had already been told no for their age, bodies, voices, appearance, or failure to fit a company’s preferred mold.
She entered as a technically trained vocalist, but the show did not let her hide inside technique. Her perfectionism became visible during recording. She would repeat takes after other people were satisfied because she could still hear the distance between the sound she made and the sound in her head.
That habit could be impressive and exhausting at the same time. Later interviews show actual growth instead of a personality press release. By 2026 she could accept that a pre-production recording was good enough for the stage it was in, stop, and save her body for the next schedule. CHIKA and MOMOKA reportedly praised her for finally leaving the studio like a person with another appointment.
JISOO was selected as one of HANA’s seven members in January 2025 with CHIKA, NAOKO, YURI, MOMOKA, KOHARU, and MAHINA. She was the only Korean member, which meant the group had somebody who could translate apps, orders, and local logistics when the “ROSE” video was filmed in Korea. She was finally the useful local friend after months of the others helping her navigate Japan.
HANA and the first year that did not slow down
HANA released the pre-debut track “Drop,” then made its major debut with “ROSE” on April 2, 2025. JISOO opens “ROSE,” which was a smart choice. Her voice arrives with weight before the arrangement expands, and the lyric about loving the self that survived hard seasons lands differently when the singer has already talked publicly about nearly leaving music.
The group moved quickly through “Burning Flower,” “Blue Jeans,” “BAD LOVE,” “My Body,” and “Cold Night,” then released its first full album HANA in February 2026. HANA won the Best New Artist prize at the 67th Japan Record Awards and appeared on the 76th NHK Kohaku Uta Gassen. That is not a quiet rookie year.
JISOO has said the pace would have been impossible alone. The seven members share personal problems and keep talking when a subject is uncomfortable. Before HANA, she doubted whether group work suited her. Now she treats direct conversation as part of making sure nobody has to shrink themselves inside the team.
Her long-term goal is not to remain a vocalist waiting for assignments. She wants a concert where each member presents a self-produced solo song. That fits CHANMINA’s stated plan for HANA to grow into members who can create their own work.
The voice file
JISOO’s tone sits lower and darker than the brightest parts of HANA’s blend. “Dark” does not mean dull or swallowed. Her vowels stay clear, the center of the note feels solid, and she can add breath without losing the pitch inside it.
She describes her role as the stillness inside HANA’s force. The group performs with heat and a lot of visible willpower. JISOO is interested in the quieter edge inside that power, especially the fragile part that appears when she does not push every note to maximum size.
Why “My Body” and “Cold Night” matter
During “My Body,” she struggled to balance her high and low registers and wanted more low-tone color in the recording. She practiced, repeated takes, and cried over it. By “Cold Night,” she felt she had found the nuance she wanted. CHANMINA gave her room to decide instead of forcing a producer-approved take onto a singer who had not finished thinking.
That arc is more useful than calling her a “power vocalist.” It tells you what she was fixing, where she heard the problem, and which release made her believe the work had changed.
| Listen or watch | What JISOO adds |
|---|---|
| “ROSE” | The opening voice and the grounded emotional entry into HANA’s debut statement. |
| “My Body” | The register problem she had to work through instead of pretending confidence solved it. |
| “Cold Night” | A lower, more settled color after that recording struggle. |
| Live stages | Control and stillness inside a group whose choreography often asks for blunt force. |
Writing and the ILLIT collaboration
In July 2026, JISOO and MOMOKA featured on ILLIT’s “I Got Your Back” and participated in the lyrics. The collaboration placed HANA’s rougher vocal texture inside ILLIT’s bright pop-rock and magical-girl framing. JISOO did not have to sand down her tone to match the song. The contrast was the useful part.

Watch JISOO in context
JISOO does not have an official solo release, so she belongs on the Members shelf, not the Solo Artists shelf. These official videos show the group voice she helped build and the credited collaboration where her darker tone changes the temperature.

Fandom file
- Food scout: She keeps notes on restaurants in Japan and abroad and plans tour meals with suspicious seriousness.
- Sports manga: Slam Dunk, Blue Lock, Medalist, and especially Garbage Time are part of her actual motivation file.
- Team function: She values direct discussion when members are uncomfortable. The quiet vocalist is not necessarily the quiet problem-solver.
- Japan and Korea: She wants HANA to work in Korea and hopes to share a stage with friends who debuted before her.
- Perfectionism: It has helped her recordings and also made stopping difficult. Her growth includes knowing which take needs another hour and which take needs sleep.
2026: first album, first tour, and the ILLIT collaboration
HANA released its self-titled first full album digitally on February 23, 2026 and physically on February 25. The album gathered the group’s origin and current work into one catalog statement rather than treating the No No Girls story as permanent introductory material.
The group began its first tour, Born to Bloom, in March and introduced “Bad Girl,” later tied to Apple’s iPhone 17 Pro group-selfie campaign in Japan. JISOO’s deeper tone remains especially useful when HANA moves between vulnerable material and songs that require more attack.
In July 2026, JISOO and MOMOKA featured on ILLIT’s Japanese track “I Got Your Back” and participated as lyricists. They also appeared at ILLIT’s Toyota Arena Tokyo tour finale. The collaboration belongs on JISOO’s member profile, HANA’s group profile, and the relevant artist/release connections because it is credited work outside the group’s own recording while still explicitly naming her as a HANA member.
HANA’s official site continues to list JISOO in the seven-member lineup and carries current tour and music notices. Her status remains active from the group’s 2025 debut to the present.
