What does the word isekai mean?

According to NYPL, Urban Dictionary, Definitions, Linguaholic, and Epic Stream, isekai is a subgenre of the fantasy genre in which a character is transported to a new world or another dimension. This is a common trope in a lot of Japanese anime and manga series. This genre has existed for a long time even in the west, like in Alice in Wonderland or The Wizard of Oz. It is no wonder that the same type of genre remains popular in Japanese anime, manga, and light novels. In these types of media, the main character is usually transported to a different dimension via some summoning, reincarnation, or by the help of a God. There is often medieval fantasy, swords, and magic. Isekai stories feature a distinct separation between real life and the fantasy world. This could also be the case in manga and video games that feature people who transport into a virtual world or virtual reality. Isekai that are a subgenre of fantasy most often feature medieval subject matter, like swords and dragons, whereas isekai that are a part of the science fiction subgenre might feature alternate dimensions or portan fantasy. 

In a fantasy literature piece, what is known as a “portal fantasy” would be equivalent to isekai anime and manga according to critic Farah Mendlesohn. In this category of fiction, a clueless character is transported into another world that they know little to nothing about. For example, in The Wizard of Oz, a young girl named Dorothy is transported from her farm life in Kansas to the mystical land of Oz, where she meets talking lions, tin men, witches, flying monkeys, and more. The popular Alice in Wonderland by Lewis Carroll also features portal fantasy. Young Alice falls down the rabbit hole from her oring life to mystical lang field with a Cheshire Cat, a silly tea party, a White Rabbit, and an evil queen. 

In Japanese works, these are often categorized ino with Isekai Ten’i, which features a character’s physical transportation to another world, or Isekai Tensei, in which a character may die or be reincarnated and their spirit is the one that is reborn or transported into another world. Popular films and anime in the isekai genre include Spirited Away which was directed by Hayao Miyazaki and released in the year 2001. In this film, a young girl accidentally transports herself into another world.
