About a week ago, Adult Swim began streaming a teaser video on Sunday for the anime adaptation of Junji Ito’s Uzumaki horror manga. The video is the same as the video streamed on August of 2019, but the description on the video reveals that the anime will debut in 2021. The anime was originally intended to debut this year. We’ve provided it below.
This four-episode horror mini-series will make its premiere on Toonami. Unfortunately, details are unclear on whether or not the 2021 delay will change anything about whether or not the anime will still debut on Toonami before reaching Japan. Hiroshi Nagahama (Mushishi) is directing the mini-series at Studio Drive. Production I.G. USA and Adult Swim are co-producing the anime. Colin Stetson (Hereditary) is composing the music.

The 1998-1999 manga follows the inhabitants of a town where strange occurrences related to a spiral shape began occurring one after the other. Viz Media originally released the manga in three collected volumes from 2007-2008, and later released an omnibus edition.
The manga also inspired a live-action horror film starring Eriko Hatsune and Fan Fhi in 2000.
Adult Swim streamed a 13-minute interview with director Hiroshi Nagahama pertaining to information about the anime. Both the teaser and the interview also aired on Toonami as part of the Toonami “panel” at the Adult Swim Con digital event.
