PLANCK STARS (プランクスターズ) is a five-member Japanese idol girl group from Hiroshima.

[2] Their antics have ranged from a member exiting the stage mid-song to buy a churro (and not returning until the very end of the concert), to releasing 300 live crickets in the audience.

[5][6] The concept was born from a desire to go against Japanese idol girl groups culture, who tend to face a lot of boundaries on who they can be and how they must act in public.

[3] In 2022, they released their first mini-album, called Ochi Omega Rema, which reached the 1st place on the Oricon Albums Chart.

[7] They have toured in countries like Thailand, United States, England, Taiwan and South Korea.
