The official website for the Kingdom anime announced that the third season is scheduled to resume in April 2021. A new teaser for the return of the new season was also revealed.
The anime's production committee announced on April 26 earlier this year that it would postpone broadcast of episode 5 and subsequent episodes of the third season. The committee explained that production was proceeding with sufficient time allocated, but the Japanese government's declaration of a state of emergency against COVID-19 heavily impacted the production schedule. The anime was then rescheduled to return in Spring 2021.
The third season of the Kingdom anime premiered on April 5th.
