What is Isekai Anime?

Isekai translates to ‘different world'. In this genre, a character or characters are transported to another world. The way this happens is varied. Sometimes a character will suddenly get transported, sometimes they die in real life, sometimes they get trapped in a game.

The type of world they're taken to also has a couple variations. It can be a game world where everything works like an RPG (role playing game) with stats, etc. It can be a similar world with small differences. It can be a strange world where magic or special powers are the norm.

Where Did Isekai Come From?

The origins of Ikesai can be traced back to ancient Japanese literature. Isekai writers often reference the story of Urashima Tarō – a Japanese folk tale. In it, the main character is a fisherman who rescues a turtle and is rewarded with a trip to the Dragon Palace beneath the sea.

In the palace, he is entertained by princess Otohime for what he believes to be a few days. When he returns home, he learns he was gone for at least 100 years. Once home, he opens the forbidden tamatebako (jewelled box) Otohime gave him and turns into an old man.

Versions of this folktale were included in Japan's nationally designated textbook all elementary school children read.

What Was the First Isekai Anime?

Urashima Tarō was adapted as an anime in 1918. It's actually one of the oldest anime created in Japan.

Other Isekai-like stories from English literature added to and influenced the genre. Stories like The Wizard of Oz, Alice's Adventures In Wonderland, Peter Pan, The Chronicles of Narnia and others.

After this initial period, Isekai was produced as manga and anime. One of the first, and most widely know isekai anime film is Hayao Miyazaki's Spirited Away.

Among the first ‘modern' style isekai anime was .hack, which presented isekai as a virtual world setting. One of the more recent shows influenced by .hack is Sword Art Online which became a successful franchise and introduced millions of new fans to the isekai genre.

What Isekai Should I Watch?

Good question! There's no shortage of shows to choose from. If you really enjoy this genre, there's also a large manga catalog you can read.

This list is by no means definitive, but a good place to start exploring what isekai anime to watch.
