No Game No Life
If you loved Shikamaru in Naruto then you will go bonkers watching this anime. What happens when you are incredible gamers but are also social outcasts.

With his NPC servants coming to life. The MC decides to make his legend known as the wizard Ainz Ooal Gown and ensure the safety of his guild Nazarick.
Sword Art Online
One of the earliest Isekai animes when isekai was not even a thing. Sword art online takes place in a virtual reality MMO game that quickly turns into a death trap when the game’s creator makes it impossible to log out. And if that wasn’t bad if you die in-game you die in real life.
Sword Art Online follows Kirito as he embarks on the journey of beating the game and escaping the death trap.
One of the wildest and most thrilling isekai anime ever made. Drifters is a truly unique anime where the plot is so amazing that you can’t help but awe at the author’s creativity. This anime doesn’t focus on MC from the modern world getting used to magic as most isekai anime do. Instead, few of the world’s most prominent historical figures are transported to another world. The MC is Toyohisa Shimazu, a rearguard in the Japanese military and one of the most hardcore warriors. With revolutionaries like Oda Nobunaga, Jeaane D arc, Abe no seimei, Grigori rasputin etc Alongside other warriors from different timelines coming against each other, Toyohisa serves as a Drifter in a war against the oppressive Ends.
If you studied a bit of history you will be shocked at the characters you will see in this anime. Honestly, a Must watch if you like action and strategy.
Rising of the Shield Hero
The Rising of the Shield Hero is one of the most-watched anime in the current years. The main MC Naofumi Iwatani, an otaku who is transported to the world of Melromarc to fulfill the mission of defeating the demons.

How not to Summon a Demon Lord
How to not summon a demon lord is the perfect isekai anime for readers who want to watch an isekai with overpowered mc and plenty of ecchi.

Log Horizon is the most chill and relaxing isekai anime. In spite of thousands of ordinary people getting trapped in a fantasy MMORPG called Elder Tale the story is still fun and quite relaxing when compared to sword art online. People are focused on adventuring out in the wild. There are multiple characters with each having their own skills and unique traits. If you want to relax and just watch an isekai that focuses on political and economic systems instead of the traditional defeat the demon lord approach this is the anime for you.
The Devil is a Part Timer
The Devil Is a Part-Timer! is one of a kind isekai anime where the demon lord travels to the human world to conquer it. Well, that was the plan but the devil is trapped in the human world without any of his demonic powers. Now how can he make his ends meet.

Now with the name Tanya von Degurechaff, she quickly rises up the ranks of the military and becomes one of the most feared leaders in history.
Gate: Thus the Japanese Self-Defense Force Fought There
GATE is one of the most unique isekai anime made. As far as I know its the only two-way isekai where the Earth is invaded by beings from another world. Youji Itami, who was just trying to get to a doujinshi (manga and novels )convention, ends up fighting against multiple invaders and saving countless lives in the process. Now he and other soldiers are selected to venture out in the new realm and establish a peace treaty to prevent a war with earth.
The Master of Ragnarok & Blesser of Einherjar
A truly unique anime which needs a prequel. The main anime is amazing but the author has skipped a lot of backstory and instead directly delved into the main combat as if trying to cram everything in the 12 episode window. Yuuto Suou is a normal teenager who happens to be summoned in another world and chosen as the new leader of the wolves. A great isekai with strategy and action elements which make it a fun watch.
The plot could have been much better though. A great story but properly executed anime in spite of amazing character designs and quality artwork.
CHOYOYO: High School Prodigies Have It Easy Even in Another World!
What happens the smartest high school geniuses have a plane crash befalls seven high school students who just happen super prodigies, standing atop their fields of politics, economics, science, medicine, journalism, martial arts, and prestidigitation!

They build a nuclear power plant.
Need to make a little money?
They take over economic control of the city.

They upend the corrupt nobility by going to war.
Zero no Tsukaima: The Familiar of Zero
What happens when you are summoned to a new world as familiar without any magical powers. Well, your life is kind of done for at least that’s what you would think. But no our MC finds a way past that to get stronger and find a way to return back to his world. Louise a young magician girl called Louise the zero because of her inability to use magic despite having a noble background accidentally on a summons a Japanese boy Saito Hiraga as her familiar. Check out his story in The familiar of Zero
Re:ZERO -Starting Life in Another World
Natsuki Subaru who happens to be our MC finds himself stuck in another world with the ability to come back to life at the same save point. The anime gets boring after a while since you are seeing the same story with different outcomes but the end is worthwhile if you have the patience to watch the entire anime. There two seasons at the time of writing. Make sure to check them out.
Restaraunt to another world
A fun and enjoyable anime where the Western Restaurant owner Nekoya uses his free time on staurdays to travel to difreent worlds and to travel serve food the inhabitants have never seen before. These otherworldly denizens experience curry, parfaits, and other tasty treats.
Its a fun lighthearted anime and if you want to relax and chill watching anime this is definitely a good choice.
Arifureta: From commonplace to worlds Strongest
One of the latest and upcoming anime with the MC being Hajime Nagumo, a boy who along with the rest of his class is transported to a fantasy world.

Even worse was that he was tricked by his classmate and falls down to the depth of the dungeon. To survive he starts eating and transmuting monsters to the point he starts absorbing their abilities as well. Thanks to his unique skills he decides to escape the dungeon and get his revenge.
Konosuba Gods Blessing on this Wonderful World
A fun and entertaing isekai anime. If you wnated an OP character then this anime is not for you. But if you wanted some fun timepass and funny characters then Konusuba is the anime for you.
Kazuma Satou dies in an embarrassing way and goddess Aqua decides to reincarnate him with a wish. He wishes that the goddess Aqua come with him in the new world. And thus begins the comical adventure of Konosuba.
Hai To Gensou no Grimgar ( Grimgar: Ashes and Illusions)
Haruhiro is the main character of this rather underrated anime. Its a great watch and honestly speaking I liked it. The main MC along with other people have teleported to the RPG world where they don’t have any memories of their previous life. From losing comrades to losing friends you get to experience the real-life of adventures without any OP powers.
Didn’t I Say to Make My Abilities Average in the Next Life?!
If you wanted a light-hearted anime with a female protagonist this is the anime for you. Misato Kurihara, a genius girl who couldn’t make any friends due to her exceptional abilities, is killed after being run over. Now she wants to be an average adventurer is the new world. So she asks go to make her abilities average.
Reborn as the noble Adele von Ascham, she soon discovers that “average” in the new world according to god takes into account the power of the absolute strongest and the absolute weakest magical creatures, resulting in her physical and magical abilities being 6,800 times stronger than that of a typical human. Make her an Overpowered wizard. Join the fun on this amazing adventure.
Isekai Cheat Magician
A decent anime but with a bad plot according to many. The plot is too common making many of the elements easy to spot. It’s still a good watch but nothing when compared to the top of our list. The story follows Taichi Nishimura and Kanade Azuma as they reincarnated into a magical world with overpowered magic abilities.
Thus, their adventure begins as the most powerful ‘cheat magicians’ trying to defeat the mastermind behind all the attacks targeted on them.
Cautious Hero: The Hero Is Overpowered but Overly Cautious
This is another extremely fun anime where the MC is just overly cautious. He loves to make advance preparations for pretty much everything. So much so that whatever he does in the name of training is always overkill.
A truly fun and comedy isekai anime. It reminds you a lot of Konosuba with a dumb goddess being the common point in both animes. Must watch if you want to have a hearty laugh.
The 8th son? Are you kidding me?
Well having a big family with lots of people is troublesome especially when it comes to inheritance. But when it comes to being the eightth son to a limited estate that’s a hard pill to swallow for Shingo Ichinomiya who was once a single Japanese salaryman until the day he fell asleep and woke up in a magical fantasy world as a young boy named Wendelin von Benno Baumeister.
Join the adventure of one of the most OP magicians as he tries to make a living in a fantasy world and hopes to amass a fortune. A fun and enjoyable anime for teens and family.

God Save our king (Kyou kara Maou)
Believe it God Save our king is one of the oldest isekai anime that was made. It’s quite fun and definitely a treat for someone who wants a mix of an OP Hero with a twist of comedy. It use to feature on Animax and that’s how I watched it in my childhood. Its an old anime but still a great watch since it has great artwork as well.
Believe it or not our hero is actually flushed down the toilet in another world with magic and rules he has never heard of. A one of kind story which follows Yuri Shibuya, your average Japanese teenager. Now he is the next Demon King due to his black hair and black eyes, traits only possessed by the demon’s royal lineage.
A truly fun and exiting anime adventure. Don’t miss it.
