Isekai is a subgenre of Japanese high fantasy fiction. It focuses on people who are transported to another world. These characters must learn to survive in their new surroundings. This transition often grants them formidable powers. These abilities give them importance they lacked in their previous lives.

Many stories use a medieval-like setting. These worlds are often populated by humans, humanoids, and monsters. Magic typically exists in these realms, but technology is limited. This setting often draws inspiration from Japanese Role-Playing Games, or JRPGs.

The mechanism of transport varies between different stories. Some characters undergo reincarnation after death. They are reborn in a new world but keep their memories. Other characters experience a transition where they move directly from Earth. This can happen through summoning by a person or a god. Sometimes a specific tool or a divine act causes the move. One character might even be pulled into a game world. A researcher named Paul Price identified six specific categories of transportation. These include reincarnation, divine acts, summoning, specific tools, being pulled into a game, and instances with no explanation.

Characters in isekai stories often possess unique advantages. Many gain special abilities referred to as "cheats." These cheats allow them to adapt and become strong very quickly. Some characters use knowledge from their previous lives to succeed. They might use skills like cooking, engineering, or medicine. These modern skills are often much more advanced than local knowledge. Physical changes are also common during the transition. A character might take on a non-human form. They might also become an infant or change their gender. Some characters even enter a liminal space between worlds to decide their role.

The history of isekai traces back to ancient folktales. The story of Urashima Tarō is a major early origin. In this tale, a fisherman visits a wondrous undersea kingdom. When he returns home, he finds 100 years have passed. Western literature also shares these themes. Examples include Alice's Adventures in Wonderland and The Wonderful Wizard of Oz. The first modern Japanese isekai novel was Warrior from Another World in 1979. The first isekai anime was Aura Battler Dunbine in 1983. Later, works like The Twelve Kingdoms helped popularize the genre in the 1990s.

In the 2000s, the genre changed through online publishing. Websites like Shōsetsuka ni Narō allowed authors to post novels directly. Titles like The Familiar of Zero and Mushoku Tensei became popular in this format. The anime Sword Art Online, released in 2012, helped spark a modern boom. This era also saw the term "isekai" become widely used. The genre's popularity is massive in modern media. In 2024, isekai anime made up 14 percent of all new anime releases. It is the second most popular genre in English-speaking territories.

In 2024, the word was even added to the Oxford English Dictionary.

Demographics and themes provide deeper insight into the genre. Analysis shows that adult men are the most common protagonists. The ratio of male to female protagonists is 2.4 to 1. The ratio of adult to teenage protagonists is 1.4 to 1. Many viewers use isekai as a form of escapism. Some "salarymen" enjoy stories where they can live as they desire. Others use the stories to fantasize about new identities. A survey of Japanese viewers found the average age to be 46. In English-speaking territories, the average age is about 30. Some stories even focus on a "slow life" to avoid being overworked.

Isekai also connects to broader cultural ideas. Some see the genre as an allegory for globalization. This idea suggests that anime adapting to foreign cultures is like an isekai protagonist. Other subgenres exist, such as "reverse isekai." In these stories, fantasy beings are transported to Earth. An early example is the 1966 series Sally the Witch. The genre has become so crowded that some contests banned isekai entries. In 2016, Shōsetsuka ni Narō placed a ban on isekai entries. Kadokawa also banned them from a novel contest in 2017. Despite this, the genre remains a global phenomenon.
