What does Isekai mean?
The other-world genre: the protagonist goes (or reincarnates) into a place with fantasy rules, often RPG rules.
Definition
Isekai is the genre in which the protagonist goes — or reincarnates — into a place with fantasy rules, often RPG rules. A portal, a summoning and a reincarnation (転生, tensei) open the same pack; sometimes a truck does the job. There are thin works and clones with a status window. Sword Art Online’s creator, Reki Kawahara, argues the label (the game is still “this world”); fandom stuck it anyway.
Fandom nicknamed that vehicle Truck-kun. English portal fantasy covers the Western cousin (Alice, Oz); in anime fandom the Japanese label won.
Origin
Isekai is Japanese 異世界: 異 (i) is other, different; 世界 (sekai) is world. The “other world” word already existed; the shelf name caught on at Shōsetsuka ni Narō (“let’s become novelists”), opened in 2004, and in Familiar of Zero (2004) fanfic. Modern ancestors often cited: Haruka Takachiho’s novel Warrior from Another World (1979) and the anime Aura Battler Dunbine (1983, Yoshiyuki Tomino). Further back, the Urashima Tarō tale.
History
In the 2000s Narō filled with isekai. The 2012 Sword Art Online anime carried the mould onto streaming; Mushoku Tensei hit the web in late 2012. Re:Zero, KonoSuba and the 2010s tensei wave closed the pack. By 2022 a season could run half a dozen TV shows with “isekai” in the title.
How it emerged
Fandom needed a shelf name for “fell into a game world.” Portal tales already existed; Narō and the 2012 anime gave the nickname shops and the algorithm then used.
Usage examples
Another isekai with a status window.
The genre is not the problem; the tired mould is.
