They were filming at a quarry site of Oyaishi (Utsunomiya-city, Tochigi) for their net digital and movie contents which was a collaborative production between TV Asahi and Toei on June 15th at around 2:00 am.



There were total 10 people transported to the hospital including 5 of Dempagumi.inc members (Furukawa Mirin, Aizawa Risa, Yumemi Nemu, Naruse Eimi, Fujisaki Ayane) and 5 staff members. Reportedly, they were poisoned by carbon monoxide, and the cause of that was due to a use of generators for the lighting device. 

According to TV Asahi, some of those 10 people have already been discharged, and by tomorrow (on the 16th), all of them will be able to leave the hospital.

The company apologized, "We were paying attention to safety during the filming, however, by producing this unfortunate result, we have caused trouble, and worry to the relevant parties. We are deeply reflecting. While wishing for a quick recovery for those who are receiving treatment, we will review the safety management thoroughly."
