(This article was updated on 19/02/2025).

While Anime might not be mainstream just yet, the global demand and popularity of the medium have skyrocketed ever since the pandemic and both anime and manga are more popular than they have ever been around the globe. More than a few anime have dominated the talks on social media within the last few years, and titles such as SPY x FAMILY, Demon Slayer, and Jujutsu Kaisen, have gone on to garner both mainstream critical and commercial acclaim around the world.

Apart from North America and European countries like France, Germany and the UK, anime is particularly popular in Asian countries such as Malaysia, India, Taiwan, the Philippines and Thailand.

Today, we will be looking at the Most-Watched Anime of All Time on the popular official anime streaming platform, Bilibili. For this list, we’ll be looking at the 15 biggest viewership figures for an anime on Bilibili Global (which operates in Hong Kong, Macau, and Southeast and South Asia), so it should be noted that the viewership figures won’t include China (which is their biggest market and where Bilibili has licensing for different Chinese suited anime).

Most-Watched Anime Ever: One Piece becomes the first anime to cross over 2 Billion Views.

1. ONE PIECE: 2.1 Billion Views

Most-Watched Anime Ever: One Piece

One Piece was added to Bilibili Asia in September 2021, and within less than a year, the anime amassed more than 1 Billion Views on the platform. Since then, it has added another billion views to its name, as the series currently is the most-watched anime ever on Bilibili with 2.1 Billion views.

After over 20 years since the debut of the anime, One Piece remains one of the most beloved franchises to ever exist and continues to break many records ever so often.

The franchise’s latest film, One Piece: Film Red, was released in 2022, and became the first movie in the franchise to make over 10 Billion Yen domestically. The film also became the 7th Highest-grossing Japanese film worldwide making over $250 million during its run.

Meanwhile, the original anime series still continues to be insanely popular around the world and has been really consistent (huge credits to Toei Animation for delivering just about every week) and has kept on reeling in new fans with it.

Oda and Toei have taken millions into an adventure of a lifetime with Luffy and the gang. So many of us have grown up with the series and continue to passionately stick with the manga or the anime to see the adventures of the Straw Hats every week. The series is truly a phenomenon of its kind, and there might never be something like One Piece ever again in our lifetime.

Most-Watched Anime Ever: Naruto sweeps the Top 5 with over 1.88 Billion views collectively.

2. Naruto Shippuden: 1 Billion Views

Most-Watched Anime Ever: Naruto Shippuden

Very few anime have had the cultural impact around the world that Naruto has had. It doesn’t matter where you live; if you are an anime fan, you have probably watched an episode or two of Naruto at some point.

Naruto has won hearts around the world with its inspiring and action-packed story alongside its nuanced and beautifully layered characters.

The series is a global sensation, and it has continued to not only live but stay relevant years after the original story from Kishimoto ended. It is not a big surprise that this epic continuation of the original series, Naruto Shippuden, has now officially crossed over 1 Billion views on Bilibili Asia and is currently on the second spot in this list.

3. Boruto: Naruto Next Generations: 538 Million Views

Most-Watched Anime Ever: Boruto

The story of Naruto continues with this spinoff anime that follows the adventures of his son, Boruto, who sets on a journey to discover his own identity separate from the looming shadow of his legendary father, Naruto, the 7th Hokage.

The series, which has been on the air for over 250 episodes, endows the legacy of the Naruto Saga into the naive, immature palms of their offspring. While Boruto: Naruto Next Generations may not be everybody’s favourite, there are plenty of Naruto fans who love the anime, and there’s enough nostalgia and heart-pumping moments within the anime that the series has made its own huge following.

4. Naruto: 354 Million Views

Of course, the original Naruto series that many of us grew up watching was also going to be on the list.

5. Hunter x Hunter: 328 Million Views

Hunter x Hunter is the crown jewel of Shonen. The series takes the genre into territories never seen before and embodies the essence of profound storytelling.

Hunter x Hunter paints a poignant painting of diverse perspectives on ideas of love, war, humanity, true strength, and purpose. Building a vast world with its intricately woven characters, the series transports its viewers into a fascinating pocket of contemplation in a gradually paced bittersweet climb.

It has not only got a great cast of main and supporting characters, but the series also features an extremely fascinating and likeable range of antagonists, who are all quite diverse in their own right. It has moments of tranquillity and general shonen fun and battles, but nothing is ever too predictable and done in a way that feels repetitive and too-tropey.

As the series progresses, it takes a much darker turn, delving into intense, universal themes that are both deeply meaningful and profoundly human. The action is thrilling, the story is captivating, and the overall experience is nothing short of brilliant. If you embark on this journey, be prepared to shed more than a few tears.

Most-Watched Anime Ever: Demon Slayer and SPY x FAMILY lead the modern pack.

Bleach and SPY x FAMILY take the next two spots on the list, with SPY x FAMILY racking over 222 million views, overtaking Demon Slayer Season 1, which currently sits at over 202 million views on Bilibili Asia.

Jujutsu Kaisen, another one of Jump’s superhit anime adaptation, is also closing on 200 million views. Season 1 of the anime series has currently amassed over 198 million views, while the manga series for Jujutsu Kaisen also recently hit 100 million copies in circulation. Apart from the Demon Slayer sequels, Detective Conan, Tokyo Revenegrs Season 1, and Haikyuu!! Season 1, are the other notable anime, which have crossed over 100 million views on Bilibili Asia.
