11 Novels

Popular Japanese action means isekai-heavy content with combat as a primary focus. These novels built their readership through consistent fight scenes, power progression, and accessible premises. The entries represent what the largest audience segment actually reads rather than critical favorites.

Japanese action often blends combat with lighter character moments, which distinguishes it from more relentless Chinese cultivation novels. These popular entries found the balance that resonated with readers: enough action to satisfy the genre promise, enough downtime to build character investment.

Kumo Desu ga, Nani ka?
4.4
(1.9K ratings)
Genre: action, adventure, comedy
The world where the Hero and the Demon King continue to oppose each other. The grand magic from the Hero and the Demon King cross over worlds and exploded in the classroom of a certain high school.
First Impressions
"Kumo Desu ga, Nani ka?" is a web novel that took me on quite the ride. It's a reincarnation story with a twist, throwing our protagonist into the body of a spider monster in a deadly labyrinth. While the initial premise might sound familiar, the execution is anything but typical. Initially, I was hooked by the unique perspective of a spider navigating a dangerous world. The early chapters focus heavily on survival, grinding, and skill acquisition. Some might find this part slow-paced, and even repetitive, but I found it quite entertaining, especially with the main character's internal monolog...

My Death Flags Show No Sign of Ending
4.5
(2.0K ratings)
Genre: action, adventure, drama
When he came to his senses, Hirasawa Kazuki, a normal university student, found himself in possession of the body of a game’s character. Moreover, it was Harold Stokes, the story’s most hated character who was even given the title 『King of Tr*sh』by the players.
First Impressions
"My Death Flags Show No Sign of Ending" has been quite the ride! Jumping into this isekai adventure, I was immediately hooked by the unique premise. It's not every day you see a protagonist reincarnated as a villain, especially one with a rather… unfortunate speech impediment. The initial chapters grabbed me with their blend of humor and intrigue. The protagonist, a university student reborn as Harold Stokes, a hated character from a game he loves, immediately has to navigate a world where his words constantly betray his intentions. It's a clever twist on the usual isekai formula and sets the ...

Overlord (LN)
4.5
(1.6K ratings)
Genre: action, adventure, drama
In 21st century, world entered a new stage of VR games…and “YGGDRASIL” is considered top of all MMORPG…but, After announcing that all its servers will be off, the internet game ‘Yggdrasil’ shut down…or so was supposed to happen, but for some reason, the player character did not log out some time ...
First Impressions
"Overlord" is a web novel that really grabbed my attention, and I can definitely see why it has such a dedicated following. It's a unique take on the isekai genre, and while it might not be for everyone, it offers a compelling experience that sets it apart from the usual light novel fare. Initially, I was drawn in by the premise: a player trapped in a game as an all-powerful undead overlord. It's a classic setup, but "Overlord" quickly establishes its own identity. The main character, Ainz (formerly Momonga), isn't your typical hero. He's a complex character, still clinging to his human past w...

EDITORS CHOICE
To Be a Power in the Shadows! (WN)
4.4
(1.6K ratings)
Genre: action, adventure, comedy
Just like how everyone adores heroes in their childhood, a certain boy adored those who hid in the shadows. One day, after living the mediocre life of a side character while undergoing frenzied training by night, he reincarnates in a different world and gains ultimate power.
First Impressions
I dove into "To Be a Power in the Shadows!" with a healthy dose of curiosity, and I've come out the other side with quite a few thoughts. This web novel is definitely... something. It's a wild ride that blends action, comedy, and fantasy in a way that's both incredibly entertaining and, at times, utterly baffling. Initially, I was hooked by the premise. The idea of a protagonist who's convinced he's living out a chuunibyou fantasy, only for it to actually be real, is comedy gold. The early chapters had me laughing out loud. It's a unique twist on the isekai genre, and I appreciated the author'...

I’m the Evil Lord of an Intergalactic Empire!
4.3
(1.2K ratings)
Genre: action, adventure, comedy
Liam Sera Banfield is a reincarnator. He had reincarnated into a fantasy world of magic and swords, but at the time the civilization had already been making advancements into outer space.
First Impressions
"I’m the Evil Lord of an Intergalactic Empire!" is a web novel that certainly sparks a range of opinions, and after diving in, I can see why. It's a blend of sci-fi, fantasy, and comedy, centered around a protagonist who's trying to be evil but hilariously failing at every turn. Whether that sounds appealing or not will likely determine your enjoyment. Initially, I was intrigued by the premise. A reincarnation story where the MC aims to be an evil overlord in a space-faring society? Sign me up! The early chapters set the stage, introducing us to Liam and the circumstances of his new life. Howe...

Kuma Kuma Kuma Bear
4.4
(983 ratings)
Genre: action, adventure, comedy
Yuna, a 15 years old girl started playing the world’s first VRMMO. She has earned billions of yen in stocks.
First Impressions
"Kuma Kuma Kuma Bear," or "Bear Bear Bear Bear" as the title hilariously translates to, is a web novel that I approached with cautious optimism. The premise is undeniably cute: a girl transported to another world with a bear suit that grants her immense power. But does the novel deliver beyond its initial charm? My first impression mirrored that of many other readers: it's a lighthearted and easy read. The writing style is simple, and the story doesn't demand much from the reader. It's perfect for when you're looking for something to unwind with, a literary equivalent of comfort food. The conc...

Death March kara Hajimaru Isekai Kyusoukyoku (WN)
3.9
(2.3K ratings)
Genre: action, adventure, comedy
Suzuki, an adult programmer, suddenly notices that he’s been thrown into a different world while wearing casual clothes at level 1. He gained high levels and treasures after using the 3 times use-disposable-magic, Meteor Shower, at once.
First Impressions
Alright, let's dive into "Death March kara Hajimaru Isekai Kyusoukyoku," or "Death March" as it's more commonly known. This web novel is definitely a mixed bag, and my experience reading it mirrored the wide range of opinions I've seen. It's got some genuinely appealing aspects, but also some glaring flaws that held it back from being a true favorite. Initially, I was drawn in by the promise of a relaxed, slice-of-life isekai adventure. The idea of an overpowered MC casually exploring a new world, enjoying the food and culture, sounded like a refreshing change from the usual high-stakes fantas...
