The funny thing about the “greatest anime of all time” debate is that nobody ever wins it. Someone always brings up Cowboy Bebop. Someone else starts campaigning for Hunter x Hunter. Then a newer fan insists Frieren: Beyond Journey’s End belongs in the same company. And somehow, everyone has a point.
Because the greatest anime don’t fade with time. They become the stories every generation of fans eventually discovers and debates.
Hunter x Hunter (2011)
Most long-running shonen anime are remembered for their fights. Hunter x Hunter is remembered for how often it refuses to play by the genre’s rules.
The 2011 Madhouse adaptation arrived after Nippon Animation’s earlier 1999 version and ultimately adapted much more of Yoshihiro Togashi’s manga, introducing a new generation of fans to Gon Freecss and his quest to find his father. But what starts as a fairly traditional adventure gradually becomes something darker and far more philosophical.
The Chimera Ant arc, in particular, transformed the series’ reputation. It’s an arc that questions heroism, humanity, and whether monsters and humans are really all that different. The irony is that Hunter x Hunter has become one of anime’s most beloved series despite never receiving a complete adaptation, thanks largely to the manga’s infamous hiatuses. Fans have spent years debating whether the story will ever truly end, which somehow only adds to its legendary status.
Death Note
Few anime have created as many new fans as Death Note. Released in 2006 by Madhouse, it arrived at a time when anime was still fighting old stereotypes in many Western countries.
Its premise was irresistible: what would happen if an ordinary student suddenly had the power to kill anyone in the world? Rather than turning into an action series, Death Note became a psychological chess match between Light Yagami and the eccentric detective L.
The anime’s second half remains divisive among fans, with many arguing that the series never fully recovered from a major turning point midway through the story. Yet even its critics admit that Death Note remains one of the most influential gateway anime ever made, introducing an entire generation to the medium.
Neon Genesis Evangelion
It’s difficult to overstate what Neon Genesis Evangelion did to anime.
When it aired in 1995, it initially looked like another mecha series. Instead, creator Hideaki Anno delivered something deeply personal, using giant robot battles as a framework to explore depression, anxiety, and human connection.
The series was also shaped by production challenges and budget constraints, which contributed to its famously unconventional ending. Fan reaction was so intense that it eventually led to The End of Evangelion, one of anime’s most celebrated and debated films.
Three decades later, viewers are still analyzing its symbolism and arguing about what certain scenes really mean. Few anime have generated that kind of lasting conversation.
Steins;Gate
Patience is practically a rite of passage for first-time Steins;Gate viewers.
Based on a visual novel by 5pb. and Nitroplus, the series initially seems like a quirky science-fiction comedy about self-proclaimed “mad scientist” Rintaro Okabe and his friends. Then it transforms into one of anime’s most emotionally devastating time-travel stories.
Its reputation has only grown over time because of how meticulously constructed it is. Details that seem insignificant in the opening episodes eventually become crucial, rewarding rewatches in a way few anime can.
For many fans, it’s the gold standard for science-fiction storytelling in anime.
Monster
Naoki Urasawa’s Monster often feels like an anomaly.
It’s a slow-burn psychological thriller with almost no fantastical elements, following surgeon Kenzo Tenma as he searches for the serial killer whose life he once saved.
Unlike many anime, Monster doesn’t rely on action or spectacle. Instead, it asks difficult questions about morality and whether evil is something people are born with or something created by circumstance.
Its length and deliberate pacing mean it’s rarely recommended to newcomers, but among longtime anime fans, it’s often regarded as one of the medium’s most mature and sophisticated works.
Vinland Saga
When Vinland Saga premiered in 2019, many viewers expected a brutal Viking revenge story. They got that, at least initially.
What they didn’t expect was a series that would eventually become one of anime’s most thoughtful examinations of violence and pacifism.
Makoto Yukimura’s manga has long been praised for its character writing, and the anime adaptation captured that beautifully. The second season’s slower, more introspective pace divided some anime-only viewers at first, but many later came to see it as the series’ emotional centerpiece.
It’s a rare historical epic that becomes more powerful the quieter it gets.
One Piece
No anime on this list has been part of people’s lives for longer than One Piece.
For more than twenty-five years, Eiichiro Oda’s pirate epic has built one of fiction’s richest worlds, introducing characters and mysteries that often pay off hundreds of chapters later.
The anime adaptation has frequently been criticized for pacing issues compared to the manga, which is one reason fans greeted the announcement of Wit Studio’s remake with such enthusiasm. Even so, its emotional highs, from Arlong Park to Marineford and Wano, remain some of the most memorable moments in anime.
As the manga enters its final saga, the conversation has shifted from whether One Piece is a masterpiece to whether its ending can secure its place as one of the greatest stories ever told.
Spirited Away
When Spirited Away won the Academy Award for Best Animated Feature in 2003, it wasn’t just a victory for Studio Ghibli. It was a milestone for anime itself.
Hayao Miyazaki’s coming-of-age fantasy introduced millions of international viewers to Japanese animation and proved that animated films could be deeply personal, emotionally complex works of art.
The film’s themes of growing up, environmentalism, and identity have only become more resonant with time. Even more than twenty years later, it remains the movie many people point to when explaining why animation deserves to be taken seriously.
Your Name.
Before Your Name., Makoto Shinkai was already respected among anime fans. After it, he became one of the industry’s biggest names.
The body-swapping romance became a global phenomenon, breaking box office records and introducing countless viewers to anime films outside Studio Ghibli.
Its success wasn’t just about its stunning visuals. At its heart, Your Name. is a story about connection and longing, themes that resonated with audiences around the world.
The film also changed the industry’s perception of original anime movies, proving they could become massive international hits without being tied to an existing franchise.
Frieren: Beyond Journey’s End
The premise alone made Frieren stand out.
Instead of telling the story of heroes defeating a demon king, it begins after the adventure is already over. The series uses that simple idea to explore grief, memory, and the way time changes our relationships.
Its rapid rise to the top of fan-ranking sites sparked plenty of debate, with some arguing it was too early to call it a masterpiece and others declaring it an instant classic.
Regardless of where you fall in that debate, Frieren has already achieved something remarkable: it made fantasy feel fresh again.
Legend of the Galactic Heroes
Long before prestige television became a buzzword, Legend of the Galactic Heroes was delivering sprawling political storytelling on an epic scale.
The 110-episode OVA examines democracy, authoritarianism, war, and leadership through the rivalry between Yang Wen-li and Reinhard von Lohengramm.
Its influence can still be felt in modern science-fiction anime, and many longtime fans consider it one of the medium’s greatest achievements precisely because it refuses easy answers.
It’s not just an anime about war. It’s an anime about power and the people who wield it.
The greatest anime don’t ask to be remembered. They simply refuse to be forgotten. What’s your favorite anime of all time?
