The wait is finally over for Rimuru Tempest fans. The official release date for That Time I Got Reincarnated as a Slime Season 4 is now locked in. The new season will begin on April 3, 2026. This news arrives alongside a brand-new trailer that gives viewers their first real look at what Rimuru and the citizens of Tempest will face next .
The announcement confirms that the isekai phenomenon is not just returning for a short run. This will be the longest season in the show’s history. The production team at studio 8-Bit has planned a massive five-cour broadcast, with the first two parts airing back-to-back through Spring and Summer 2026 .
The April 3 Premiere Date and Where to Watch
Mark your calendars for Friday, April 3, 2026. The series will first air in Japan on Nippon TV’s FRIDAY ANIME NIGHT programming block at 23:00 JST . For international audiences, the news is just as good. Crunchyroll has officially confirmed they will stream That Time I Got Reincarnated as a Slime Season 4 as a simulcast starting on the same day .
The streaming platform will make the episodes available across North America, Central America, South America, Europe, Africa, Oceania, the Middle East, and CIS territories . While the exact episode time for global viewers is yet to be announced, it typically follows the Japanese broadcast within a few hours. This ensures fans in the USA, UK, Canada, Australia, and India can watch Rimuru’s new adventures almost as soon as they air in Japan .
A Historic Five-Cour Broadcast Schedule
This season is breaking records simply by its length. That Time I Got Reincarnated as a Slime Season 4 will run for a total of five cours. In the anime world, one cour typically represents a three-month broadcast period .
The first two cours will air consecutively starting April 3. This means fans will get roughly six months of continuous new episodes without a break. The remaining three cours are scheduled to air later, though specific dates for those后续 parts have not yet been released . This extended schedule suggests the anime will cover a substantial amount of source material from the original light novels.
New Trailer and Theme Song Performers
Alongside the release date, the official staff unveiled an exciting new trailer. The promotional video showcases rising political tensions and expanding alliances. Viewers see Rimuru alongside key allies, facing threats that appear larger than anything Tempest has dealt with before .
The trailer also previewed the season’s new music. The opening theme song, titled “Esoragoto,” will be performed by renowned anime singer Eir Aoi. The ending theme, “Katsubō,” will be performed by the artist CiON . Both songs are featured in the new footage, giving fans a taste of the season’s energetic and emotional tone.
