The official website for the Encouragement of Climb: Next Summit anime has announced that the series is scheduled to premiere in Japan on October 4, 2022.

The anime will have 12 episodes, each running for 30 minutes. This will mark the first time the anime has had full-length episodes, as previous seasons only had five- or 15-minute episodes. The first four episodes of the new anime will be compilations of the previous anime series’ episodes with new short stories added. However, Episode Five and onwards will have completely new stories.

The first season of Encouragement of Climb premiered in 2013, followed by the second season in 2014. The third season premiered in July 2018. Crunchyroll simulcast all three seasons as they aired in Japan.
