If you’re new to isekai, you’ve come to the right place! Here you will find a quick guide to isekai itself, as well as a list of some of the best isekai manga to get you started reading in the genre.

First things first: what is isekai? “Sekai” is Japanese for “world”, with the prefix “i-” meaning “other” or “different.” So, logically, the isekai genre revolves around stories involving the protagonist being transported to another world in one way or another (including by reincarnation or summoning). You can think of it as something like the Japanese equivalent of portal fantasy.

The concept of isekai has been long-standing in Japanese culture, appearing as far back as in traditional folk tales such as Urashima Tarō, the story of a fisherman transported to a palace under the sea on a turtle’s back. Upon his return home, he discovers that though he seemed to only have spent a few days at the palace, over 100 years had actually passed in his world. A more recent, and especially recognizable example of isekai would be the Studio Ghibli film Spirited Away, in which 10-year-old Chihiro finds herself working at a bathhouse in the spirit world after her parents are cursed and turned into pigs for eating the food of the spirits.

In terms of books, isekai is especially huge in the light novel format, having been especially popularized by such titles as Sword Art Online. But there are plenty of manga in the genre as well, so here are some of the best isekai manga for you to enjoy!

Under the broadest definition of the genre, stories about being transported between times can also fall under the isekai umbrella. This classic manga follows Kagome, a high schooler in modern-day Japan, who one day falls down a well at a shrine. She is transported to the Sengoku period and meets Inuyasha, a half-demon. The two must journey to recover the scattered fragments of the Shikon Jewel, a powerful and sacred gem.

The Abyss is home to monsters called Chains, and Oz befriends one named Alice, who helps him in his attempt to escape the Abyss as well as in his journey to discover the deeper meaning behind his own existence.

Best Isekai Manga Adapted From Light Novels

As I mentioned earlier, isekai as a genre looms quite large in the world of light novels. Because the formats are so closely related, many of these find their way to become manga adaptations, as the selection of titles below!

I'm in Love with the Villainess by Inori and Aonoshimo cover

I’m in Love with the Villainess by Inori and Aonoshimo

Rei Ohashi is a normal office worker who, in a (sadly) unsurprising depiction of Japanese work culture, works herself literally to death. However, she is reincarnated as the protagonist of her favorite otome game. But, instead of following one of the game’s original three routes in which she could have a romance with one of the princes, Rei decides to use her existing knowledge of the game to try to woo Claire, the main antagonist.

When she is killed in an earthquake by being crushed by fallen books, her last wish is to be reborn into a world where she can do nothing but read forever.

With her knowledge from her previous life, Urano (now a 5-year-old girl named Myne) decides to create more books herself.

Overlord by Satoshi Oshio and Hugin Miyama cover

Overlord by Satoshi Ōshio and Hugin Miyama

This manga is adapted from a light novel series written by Kugane Maruyama and illustrated by so-bin. A popular virtual reality game is being shut down, and Momonga, the leader of a powerful guild within the game, decides to stay logged in until the very end, even though all of his friends have already quit. However, once the shutdown occurs, Momonga finds himself within the game world in the body of his avatar. He sets out through the game world to investigate what happened and to see if there is anyone else who was transported from the real world as well. It’s an interesting look at morality, exploring a character’s psychology in a world where ethical lines have been obscured.

Restaurant to Another World by Junpei Inuzuka and Takaaki Kugatsu cover

This slice-of-life variation on isekai highlights the stories of the restaurant patrons as they interact with the owner and each other while enjoying delicious meals.
