The idol group reportedly apologized in a message to fans. In their apology, the group revealed that they had fed a male fan dish soap for fun.

The members, as a joke, made a male fan drink dishwasher soap. We are so sorry. Usually, we make sure our fans aren’t harmed during our fun live (shows).

PLANCK STARS had held a fan meeting event. On this day, they fed a male fan dish soap. The male fan reportedly refused several times before eventually drinking the soap.

The male fan, in an interview with a media outlet, stated that he had made sure it was safe to drink before doing so.

I made sure it was safe before drinking it. I had to rinse several times because bubbles kept coming out. If I become unwell, I will go to the hospital.

This isn’t the first time that the group’s antics have landed them in controversy. In September 2022, the group held a contest to see which member could sell the most tickets for a Polaroid event. Controversy struck when the group stated the member who sold the least amount of tickets would debut in an adult video. This controversy ended up in laughter when it was revealed the “loser” for the event was their dog, Puri-chan and the “adult video”, also known as AV, ended up being an animal video.

Meanwhile, PLANCK STARS is a Japanese underground idol group whose entire goal is to be different from the traditional Japanese idol group. For example, one of their antics was when member Anaru Rairai left during the middle of a performance to buy a churro. She didn’t end up returning to the stage until the end of the concert.

The group debuted in 2018 and disbanded in February 2025. However, it was announced they would reorganize and return in July 2025.
