17 Novels

Adventure reincarnation novels from Japan often feature protagonists exploring new worlds after being reborn. The reincarnation provides the isekai setup while the adventure tag emphasizes exploration and discovery over pure combat or romance. Dungeons, travel, and new experiences drive the narrative.

Japanese adventure tends to include more slice-of-life moments than Chinese versions, with the journey itself being enjoyable rather than just a means to power. The reincarnation element gives protagonists useful knowledge or abilities that make exploration feasible. These 17 balance exploration with the reincarnation premise effectively.

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...

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'...

(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.

Apotheosis of a Demon – A Monster Evolution Story
4.5
(798 ratings)
Genre: action, adventure, drama
A back-to-basics(? ) monster evolution novel.
First Impressions
"Apotheosis of a Demon – A Monster Evolution Story" promised a unique take on the isekai genre, and after diving in, I can say it mostly delivers, though not without a few stumbles along the way. The story follows Shedy's journey from abused human to demon goddess, and it's a wild ride. I was immediately drawn in by the premise. A protagonist who isn't afraid to get her hands dirty and doesn't bother with "righteous" justifications? Sign me up! The initial chapters are compelling, and I found myself eager to see how Shedy would navigate this new, dangerous world....

Genre: action, adventure, comedy

First Impressions
Isekai Tensei Soudouki is one of those novels that really grabbed my attention with its unique premise. A single body housing three distinct souls? I was definitely intrigued. While it has its share of familiar isekai tropes, it also attempts to carve out its own identity. The initial hook of this story is undeniably strong. I was immediately drawn to the dynamic between the three personalities inhabiting young Bard Cornelius: his original self, a money-obsessed samurai from the Edo period, and a chuunibyou-afflicted modern-day otaku. This trio makes for some genuinely humorous and interesting...

Otome Game no Heroine de Saikyou Survival (LN)
4.5
(414 ratings)
Genre: action, adventure, fantasy
A girl Alicia lived as an orphan in a world of sword and magic Ciel. One day, she learned that she was an “otome game’s heroine”.
First Impressions
"Otome Game no Heroine de Saikyou Survival" certainly grabbed my attention with its intriguing premise. We're thrown into a world that initially feels like a typical otome game setting, but quickly veers off the beaten path. Alicia, our heroine, isn't interested in romance; her primary focus is survival. I was immediately drawn in by the promise of a protagonist who prioritizes strength and skill over capturing the hearts of potential love interests. What I appreciated most was the subversion of otome game tropes. Instead of the usual focus on romance, we get a hardcore leveling-up story. Alic...

First Impressions
This title certainly grabbed my attention, and after diving in, I can see why so many readers have enjoyed this novel. It's a blend of familiar tropes with some refreshing twists that kept me engaged. The premise is intriguing: Sonia, aware of her past life as an anime otaku who knows this world as a story, is determined to avoid her villainous fate. The initial chapters are strong, setting up a world ripe with political intrigue and personal stakes. The broken engagement trope is flipped on its head when Sonia unexpectedly takes Bill, the knight with an anti-witch sword, as compensation. I wa...

First Impressions
"The Magical Revolution of the Reincarnated Princess and the Genius Young Lady" is quite a mouthful, but I found myself surprisingly charmed by this isekai fantasy. It's not your typical otome game reincarnation story, and the blend of magic, political intrigue, and slow-burn yuri romance creates a unique flavor that kept me engaged. The initial hook is strong. We're thrown into a world where the protagonist, Anisphia, retains memories of her past life and is obsessed with magic, even though she can't wield it traditionally. Instead, she pioneers "Magicology," using scientific methods to revol...

Tensei Shitara Slime Datta Ken (WN)
4.2
(1.5K ratings)
Genre: action, adventure, comedy
A man is stabbed by a robber on the run after pushing his coworker and his coworker’s new fiance out of the way. As he lays dying, bleeding on the ground, he hears a voice.
First Impressions
Tensei Shitara Slime Datta Ken, or Slime Isekai as it's often called, is a web novel that I dove into with a good deal of anticipation, given its popularity and numerous adaptations. Overall, I found it to be a mixed bag, with some truly enjoyable elements weighed down by some frustrating shortcomings. The initial premise – a salaryman reincarnated as a slime – is undeniably intriguing. The early chapters are engaging, and I was quickly drawn into Rimuru's efforts to build a life and community in this new world. The idea of a slime, of all things, becoming a powerful leader and nation-builder ...

Clearing an Isekai with the Zero-Believers Goddess – The Weakest Mage among the Classmates (WN)
4.2
(1.2K ratings)
Genre: action, adventure, comedy
Makoto Takatsuki is a normal high school student and a hardcore RPG player. However, “normal” goes out the window when his whole class is involved in a bus crash and whisked away to another world!
First Impressions
This title is a mouthful, but after diving in, I found a surprisingly enjoyable isekai story. It's not without its flaws, but overall, it's a refreshing take on a well-trodden genre. Initially, I was wary. Another weak-to-strong isekai? I've read my fair share. However, what immediately grabbed me was the lack of the usual isekai tropes. The MC isn't bullied or abandoned, and his classmates don't suddenly become enemies. Instead, there's a sense of normalcy, which is a welcome change. He's weak, yes, but he's also not a complete idiot, and that already puts it ahead of some others....
