Say Hello To The Big 3 of Isekai Anime In 2026

by

2026 looks like it will be an amazing year for anime fans! Lots of popular manga are being turned into anime series, and several well-loved shows – including the famous “Big Three” – are returning with new seasons.

Isekai, a hugely popular anime genre in Japan, is experiencing a major resurgence. 2026 promises to be a fantastic year for fans, as the three biggest Isekai series – That Time I Got Reincarnated As a Slime, Re: Zero, and Mushoku Tensei: Jobless Reincarnation – are all scheduled to return after a period of inactivity.

Isekai Is One Of The Most Popular Anime Genres In Japan

Isekai Anime Have Gained Great Popularity Overseas Too

Among the many fantastic anime shows available, the Isekai genre has remained consistently popular and is now considered mainstream. Isekai stories center around characters who end up in a different world than the one they originally came from. Most of the time, these stories involve a character being reborn or transported to this new world, though there are always exceptions.

Isekai stories are known for their detailed and imaginative worldbuilding, often transporting characters to fantasy realms. While consistently popular in Japan, the genre has become somewhat crowded with new releases. However, interest in Isekai is growing internationally, with fans discovering many excellent new series, including those with similar themes. A great example is ‘Lord of Mysteries,’ a Chinese anime that aired in 2025 and falls into this category.

Recently, the series Solo Leveling gained huge popularity, building on the success of the Isekai genre. Isekai stories offer a lot of possibilities, and 2026 could be a big year for them with several major anime making a comeback.

Three Of The Biggest Isekai Series Are Making a Comeback In 2026

While 2025 saw a lot of new Isekai anime, 2026 is set to be even bigger. Three of Japan’s most popular Isekai series have been officially confirmed to return next year, according to their production studios.

  1. Re:Zero Season 4
  2. That Time I Got Reincarnated As A Slime
  3. Moshuko Tensei: Jobless Reincarnation Season 3

Anime fans are eagerly anticipating these new shows, hoping they’ll bring a fresh and exciting take to the popular ‘isekai’ genre.

Re:Zero Season 4 Is Coming in April 2026

Re:Zero is widely considered the best in the Isekai genre, and most fans agree. It played a huge role in making Isekai anime popular internationally, and the anime continues to adapt the exciting source novels.

I’m so excited for more Re:Zero! It’s been running since 2016, and we’ve already had three amazing seasons. But the best part? A fourth season is coming in April 2026! I, like so many other fans, am really looking forward to seeing what Subaru Natsuki gets up to next and diving deeper into all the incredible stories and secrets this world has to offer.

That Time I Was Reincarnated As A Slime is Getting a New Movie And Season 4 Begins April 2026

That Time I Got Reincarnated As A Slime is a hugely popular isekai anime, becoming one of the biggest series in Japan. Its success is clear, as it consistently receives new projects and currently tops the charts on Crunchyroll, the popular anime streaming platform, with the most user ratings. The series has already aired three seasons and is set to return in April 2026 with a fourth. But that’s not all – even more exciting things are planned for fans in 2026!

A new movie based on the popular anime That Time I Got Reincarnated as a Slime is coming out in February 2026. Titled That Time I Got Reincarnated as a Slime: Tears of the Azure Sea, it will first be released in Japan on February 27th, with plans for international release soon after. Many fans are hoping this film will become the next big anime movie success, following in the footsteps of hits like Demon Slayer and Chainsaw Man.

Mushoku Tensei: Jobless Reincarnation Season 3 Is A Highly Anticipated Release For July 2026

Besides popular series like Re:Zero and That Time I Got Reincarnated as a Slime, another major isekai anime, Mushoku Tensei: Jobless Reincarnation, is returning this year. While the series has faced some controversy, it’s had a significant impact on the popularity of isekai anime worldwide. Its unique setting and story have captivated many viewers, leading to a third season renewal. Mushoku Tensei Season 3 is scheduled for release in July 2026, not long after the new seasons of the other two big isekai shows. Hopefully, the upcoming story arc will be even more engaging than previous ones.

Other Big Isekai That Could Return In 2026

Popular isekai anime like That Time I Was Reincarnated as a Slime, Re:Zero, and Mushoku Tensei have gained a large following in both Japan and internationally. However, these aren’t the only series potentially returning this year. KonoSuba: God’s Blessing on This Wonderful World! is another beloved isekai anime that fans are hoping will get a new season.

Konosuba is incredibly popular, and fans were thrilled to hear it’s been renewed for a fourth season. Many believe it could become one of the biggest shows in the ‘isekai’ genre, potentially returning in 2026. Currently, there’s no confirmed release date for Season 4, but late 2026 is a likely possibility, though 2027 isn’t ruled out. Whenever it arrives, the new season promises to be fantastic.
