Rumors of JYP’s New Girl Group and the Stirring Reactions from Fans

Rumors of JYP’s new girl group spark excitement and debate.
Speculated lineup includes multinational trainees.
Fans question if JYP can manage too many girl groups.

In recent days, X (formerly Twitter) has been abuzz with videos and photos of several teenage girls dressed in dark uniforms entering and leaving the JYP Entertainment building in Seoul. A fanbase account, Judy’s JYPNGG, shared photos of the trainees who appeared to be attending their training schedule. In the post, the account claimed that the JYP New Girl Group (shortened to NGG) would consist of five trainees from Korea, Japan, and Australia. The news spread quickly—the tweet was viewed millions of times and sparked lively discussions among fans. While many were excited to welcome the new “younger sisters” of ITZY and NMIXX, others expressed concern that JYP might be adding yet another group without giving enough attention to the existing ones. Below, we’ll look into who the rumored trainees are and how fans are reacting to this unconfirmed debut.

The Lineup of Trainees: Eri, Yinah, Tomi, Marise, and Jinni

According to circulating rumors, the five trainees allegedly set to debut under NGG are Eri, Yinah, Tomi, Marise, and Jinni. In a leaked list shared by fans, Eri is described as a Korean–Japanese trainee born on December 17, 2008, while Yinah is a Korean trainee born on September 15, 2007. Tomi is said to be from Japan, born May 3, 2007, whereas Marise is noted as a Korean–Australian trainee born November 7, 2006. Lastly, Jinni is listed as a Korean trainee born February 12, 2006. These names and birthdates remain speculative, as JYP Entertainment has not released any official statement. The leak is believed to have originated from a Korean community site where a photo of the five trainees walking together was posted—this image then spread across social media, fueling speculation that they are the prospective members of the new girl group (see image below).

In addition to that photo, the same account also shared a video showing six trainees leaving the JYP building in early September. The uploader noted that their hair colors matched those of the five trainees photographed in August. This sparked further speculation: could NGG actually consist of six members? Or was one of them just a staff member accompanying the group? JYP typically keeps trainee details under wraps until close to debut, making it rare for such leaks to be clarified. Still, the presence of multinational trainees aligns with JYP’s strategy of forming groups with global appeal. As a major entertainment company, JYP Entertainment functions as a record label, talent agency, music producer, concert organizer, and publisher. With multiple subsidiaries and divisions outside Korea, it is not surprising that they aim to replicate the success of groups like TWICE, which combined Korean, Japanese, and Taiwanese members.

Fan Concerns and Controversy: Can JYP Handle So Many Girl Groups?

These debut rumors have not only fueled excitement but also stirred backlash among fans. 

One X user wrote, “this company keeps debuting girl groups and then don’t know what to do with them. I’m so tired,” while quoting the rumored NGG lineup. 

This reflects broader worries that JYP is expanding too quickly without maximizing the potential of existing groups. Other fans voiced similar frustrations:

“my point is that the talent among every girl group in jype is actually insane and unique. they all have everything it takes to be the biggest ggs out there but they keep wasting opportunities. nmixx released one of the best song this year, yeji released soty and the promo? 0/10.”

“like why wasn’t this everywhere? genuinely? and that’s definitely on them cause this had everything to be HUGE.”

“and this?? like why? jype just doesn’t know how to make NOISE around the releases of most of their groups. this is excellent and should’ve been everywhere”

“difference is hype has better promotion unfortunately that’s why all their girl groups do well.”

“Hybe can actually promote their ggs and help them sustain popularity unlike jyp who has three ggs who just get pushed to the back along with the two bggs that’s also get pushed to the back.”

“notice how hybe can actually promote their groups though.”

“Each one of these gg are under diff companies with diff ceo, producers and staff—it’s not the same.”

“JYPE debut 5 GGs in 7 years, Ador debut 1 GG, Source Music 1 GG, Belift 1 GG, Hybe America 1 GG… see the difference, Hybe is corporation not label.”

“What GGS from JYP last 7 years? It’s only Itzy (2019), NiziU (2020), Nmixx (2022).”

“Jyp is company hybe are label, you can’t compare company with label. If you want to compare pick any company under hybe; bh only has 3 groups, source only has 1, belift has 2, koz has 1, hybe jpn 2, hybe us 1, pledis has 2. So which company you want to compare?”

These remarks highlight broader unease. Since 2019, JYP has consistently rolled out girl groups. ITZY debuted on February 12, 2019, with the mini album It’z Different. The group—Yeji, Lia, Ryujin, Chaeryeong, and Yuna—became known for their “teen crush” concept and record-breaking debut song Dalla Dalla, earning them the “Rookie Grand Slam” with five Rookie of the Year awards in Korea. A year later, JYP partnered with Sony Music Japan to form NiziU through the Nizi Project. The nine-member group debuted on December 2, 2020, with the single Step and a Step, finding success in both Japan and Korea. In 2022, sub-label SQU4D launched NMIXX, originally with seven members. Their name combined “N” (now, next, and unknown variables) with “mix” to symbolize diversity. They debuted on February 22, 2022, with the single album Ad Mare and the title track O.O. By December 2022, however, one member, Jinni, left, leaving NMIXX as six.

Not stopping there, JYP and Republic Records debuted the global girl group VCHA in 2023 through the America2Korea (A2K) program. By 2025, after two members departed, the group rebranded as Girlset with four members—Camila, Lexi, Kendall, and Savanna. With so many launches in just a few years, fans are worried the company is stretching its resources too thin. Many compare JYP to HYBE Corporation. Some argue the comparison is unfair since HYBE is a parent company overseeing multiple labels—Ador, Source Music, Pledis, Belift, KOZ—while JYP functions as a single label managing all its groups. Others point out differences in approach: HYBE is known for aggressive global promotions, while JYP is seen as more conservative, especially with non-Korean groups.

For now, there is no official information on the name, member count, or debut schedule of NGG. JYP Entertainment is known to introduce members gradually ahead of debut, as they did with NMIXX and NiziU. With the company’s strong track record and history of producing successful acts, NGG will likely attract attention. But their success will depend on how JYP manages schedules, promotions, and whether they can give this group a unique identity. Until official confirmation arrives, these rumors remain a reflection of both the hopes and concerns of fans who follow the K-pop industry closely.
