SNACK three-line summary
- ILLIT will appear at major Japanese music festivals in both July and August.
- The key point is two joint stages with CUTIE STREET. At FNS and Mezamashi WANGAN Festival, the two groups are set to perform each other’s hit songs in a crossover format.
- On August 9, ILLIT is also scheduled for the main stage at LuckyFes 2026, making this a warm-up point ahead of activities for the group’s second Japanese single, I Got Your Back.

Snack Girls editor note
AIKO: “Putting ILLIT and CUTIE STREET together on one stage feels like a move to widen their points of contact with local Japanese fandoms.”
Red: “When FNS, Mezamashi, and LuckyFes are all connected, this becomes more than a single event. It starts to look like a summer-season route.”
Kirari: “If they are swapping songs with CUTIE STREET on stage, there should be quite a few moments that spread as clips.”
ILLIT enters today’s first regular news item in the idol section. According to reports on the 17th, HYBE Music Group label BELIFT LAB said ILLIT will appear in succession at major Japanese music festivals this summer.
The most eye-catching part is the joint stage with Japanese idol group CUTIE STREET. ILLIT will perform with CUTIE STREET on Fuji TV’s live-broadcast 2026 FNS Music Festival Summer on July 1, and at the Mezamashi WANGAN Festival at Toyosu PIT in Tokyo on August 4.

Why this pairing stands out
According to News Culture, the two teams are preparing a collaboration stage in which they will perform ILLIT’s Almond Chocolate and CUTIE STREET’s Can’t We Just Be Cute? in a crossover format. This is not simply a case of both names appearing on the same event lineup. It is a setup where fans of both groups can check out clips in one place.
For readers following the scene from Korea, this combination is fairly easy to understand. ILLIT is a HYBE-affiliated girl group actively moving with global short-form trends, while CUTIE STREET is an idol team that has been quickly drawing attention locally in Japan. Their meeting on the same summer festival line is a scene that shows the intersection between K-pop and Japan’s idol scene.

LuckyFes main stage also scheduled
The joint stages are not the only schedule. ILLIT will also appear at LuckyFes 2026, held on August 9 at Hitachi Seaside Park in Japan. News Culture reported that ILLIT will perform on the RAINBOW STAGE, which can accommodate about 30,000 people.
This schedule also connects with the flow of the group’s Japan tour. Reports also mentioned the sold-out run across all dates of the Japan tour, along with activities for ILLIT’s second Japanese single, I Got Your Back, scheduled for release in July. In other words, this news is closer to a bundle of schedules that significantly expands ILLIT’s exposure during Japan’s summer season than just one “event appearance.”
