Before Natsuki Subaru ever stepped out of a convenience store and into the cruel, looping world of Lugnica, the isekai genre was a vastly different landscape. While Re:Zero – Starting Life in Another World is often credited with deconstructing the genre’s power fantasies and introducing suffering as a central mechanic, it didn’t invent the portal fantasy.
Isekai has only become associated with cheat systems, harems, and power fantasies in recent decades. From way back, the theme is a mere tool to explore different ideas, including romance, family drama, and, of course, high-fantasy adventures.
The 45 Best Isekai Anime Of All Time, Ranked (2026 Edition)
From classics to modern standouts, these are the best isekai anime of all time—ranked by impact, staying power, and relevance in 2026.
Digimon Adventure (1999)
Digimon Adventure, which fairly recently received a reboot, is the original anime series of the Digimon franchise. Many consider it as Pokemon‘s rival, especially with the similar monster-raising theme. But what many may have forgotten is that it’s an isekai narrative even before isekai dominated the anime sphere.
The anime’s story starts with seven kids going to a summer camp only to be given a mysterious device that transports them into the digital world. In this world, they meet curious creatures referred to as Digimons. The Digimons give them general information about the world. Unlike modern isekai with overpowered main characters, these seven kids are only equipped with their Digivices and Digimon companions to find a way back to their original world. Naturally, their adventure is far from an easy one. After all, the digital world is filled with both glorious wonders and unknown evils.
Inuyasha (2000)
Takahashi Rumiko is a legend for a reason, and Inuyasha is her take on the time-travel isekai. Even after decades, the anime still holds up very well. Unlike many modern isekai, Inuyasha‘s main character isn’t just trapped in the other world. She frequented both worlds, even bringing modern-day conveniences like modern medicine and snacks to the past.
The story follows Higurashi Kagome. On her 15th birthday, a centipede demon drags the unfortunate lass into her family shrine’s old well. The moment she emerges, she finds herself already 500 years in the past. Even though it seems to be the same timeline, this period is infested with demons. These demons relentlessly hunt her for the wish-granting Shikon Jewel, which she didn’t even know she was carrying. Unsurprisingly, the jewel accidentally shatters. Kagome is then forced to team up with the hot-headed half-demon Inuyasha to search for the shattered pieces. More than the pieces, they also discover love.

Fushigi Yugi
If Inuyasha is more supernatural fantasy than romance, Fushigi Yugi is the opposite. It’s a shoujo isekai that focuses on the main characters’ romantic relationships. In fact, those relationships primarily drive Fushigi Yugi‘s narrative.
The story is set in the fictitious world of The Universe of the Four Gods, a book that the main characters Miaka and Yui found in the National Library. Upon reading the said book, both are pulled into its world, which heavily resembles ancient China. Miaka becomes the Priestess of Suzaku, who is destined to gather her seven Celestial Warriors to summon a god and grant her wish. Yui, on the other hand, becomes her rival from a competing nation.
Spirited Away (2001)
This Studio Ghibli masterpiece is the purest form of isekai. There are no menus, no stats, and no clear rules. Even so, it perfectly captures both the wonders and dangers of entering an entirely new world. Despite its age, this award-winning Studio Ghibli film continues to be honored in the modern day and for good reasons.
It follows Chihiro and her parents. While moving to a new neighborhood, the trio stumbles into what they think is an abandoned theme park. The parents are lured into a stall offering mouth-watering dishes. Upon partaking, however, they mystically get transformed into pigs. That’s when Chihiro discovered she is trapped in a realm of Japanese folklore. She is then forced to take a job at a bathhouse run by the witch Yubaba as she finds a way to break her parents’ curse and a way home.
Sword Art Online (2012)
While Sword Art Online, or more commonly referred to as SAO, isn’t as old as the others, it still deserves recognition due to its contribution to the genre. After all, it’s the series that popularized many modern isekai tropes like gaming systems, overpowered protagonists, and even virtual reality.
The plot is set in a future wherein virtual reality has progressed to the point of players being able to fully dive into the virtual world. But when thousands logged into the titular game, they realized they had been trapped. They can no longer log out. To make matters worse, dying in-game also means dying in real life. The only way out is to clear all 100 floors of the floating castle, Aincrad.
