When it comes to anime and manga, shonen series have always dominated at the very top, and that has been the case for the last 40 or so years. With the official release of Dragon Ball on November 20, 1984, shonen series have never truly stopped their domination. With the end of Dragon Ball came the wave of the Big Three only a couple of years later, which dominated up until the mid-2010s.
That said, slowly but steadily, the era of shonen anime series is officially coming to an end, and it is time for fans all over the world to accept that. With shonen series slowly losing steam and the biggest of hitters, that is, One Piece, now slowly reaching its conclusion, the age of shonen anime is reaching its conclusion. A completely new age with new manga is set to dominate in this new era.
Shonen Anime Is On A Decline With One Piece Conclusion Edging Closer
Shonen series have been absolutely sensational over the last couple of decades, and much of that is down to the incredible formula that was first carved by Dragon Ball and Akira Toriyama, which later paved the way for even more exciting stories to follow, such as One Piece, Naruto, and many others. The boom of shonen popularity most certainly came with Dragon Ball, but the Big Three era certainly carried that to a completely new level. In fact, Dragon Ball’s popularity reached such a level that it endures to this day. One Piece, on the other hand, continues to grow bigger than ever with each passing year, and Naruto has endured the test of time as well, preparing for its own return later down the line in 2027.
Clearly, shonen series made fans all over the world fall in love, but with the age of the Big Three officially wrapping up with the impending end of One Piece, what follows next is far weaker. When Naruto and Bleach ended, Shueisha’s Weekly Shonen Jump replaced these series with heavy hitters like My Hero Academia, Demon Slayer, Jujutsu Kaisen, and Chainsaw Man. However, all these stories ended up proving to be short serializations and reached their conclusion as well.
Shonen Jump right now is at its very weakest, and for the very first time, viewership for the magazine fell under a million in 2026, which is a telltale sign of the fallout that is coming with a lack of good shonen stories. While series like Kagurabachi and Ichi the Witch certainly do help out the magazine to a certain extent, neither of them is on the same level of popularity as their legendary predecessors. Furthermore, reader popularity recently showed in Japan that Kagurabachi is steadily losing steam among the readers, which once again goes to show that Shonen Jump doesn’t have any major reliable hits. Consequently, there is no upcoming major anime hit for fans to enjoy either. With One Piece steadily heading towards its end, the end of an era for shonen anime is on the horizon, and with its end comes the end of the big boom of shonen, which once started with Dragon Ball.
Why New Generation Shonen Series Will Never Reach The Level Of The Big 3
When Naruto and Bleach ended, a new wave of exciting series began with the likes of Demon Slayer, Jujutsu Kaisen, My Hero Academia, and Chainsaw Man. Needless to say, these series reached incredible heights of popularity. Demon Slayer ended up becoming one of the most popular series of all time globally, while others competed with it along the way. Where these series failed was standing the test of time.
All of these series ended up being shorter serializations compared to legendary series like One Piece, Naruto, and Bleach. In fact, One Piece, which began serialization over a decade before these series, is still ongoing, while these stories have already reached their conclusion. It is the sudden and consecutive conclusion of these series that has pushed Shonen Jump to the point where it is today, and what followed them has not managed to make a big impact.
Right now, the two biggest series that Jump has among the new generation stories are Kagurabachi and Ichi the Witch, and none of them are as exciting as one would have hoped. In other words, once One Piece reaches its conclusion, Jump will have nothing big to sell to readers, and viewership will drop even further and be restored to what it used to be before the shonen boom. It is at this point that fan attention in Japan will turn to a completely different demographic that is Seinen manga.
The Era Of Seinen Anime Will Officially Begin
While shonen stories are steadily losing steam, seinen stories are growing at a rapid pace. In fact, seinen series have always existed and always operated at an incredibly high level, but never received the same level of attention as shonen stories. With shonen series steadily losing steam, seinen manga will get their own anime adaptations at a much higher rate than ever before, and they will have an opportunity to be spread around the world at a much faster rate.
There are quite a lot of exciting seinen stories that are currently going under the radar globally, and these include series like Mujina Into the Deep, Heavenly Delusion, and Under Ninja. These stories are incredible in their own right and have what it takes to match stories like Jujutsu Kaisen, Demon Slayer, My Hero Academia, and Chainsaw Man. They might even go on to rival series like Naruto and One Piece in terms of popularity if given the chance to expand.
So far, they have not been given the platform they require to become global phenomena. If shonen stories eventually end up losing steam, one of Japan’s biggest industries will have to look for different avenues that could allow for these amazing stories to receive the platform that they deserve. Only then can these stories be brought to global recognition and be given their own anime, which could then potentially lead to a new era of Seinen and a boom in the anime industry.
For now, One Piece is single-handedly carrying the shonen anime industry, and that will continue for the years to come. Eventually, however, One Piece will reach its conclusion, which will then usher in a new era of seinen stories. We can only hope that we get some new exciting Shonen releases over the course of the next few years to mitigate the loss of viewership in Shueisha’s Weekly Shonen Jump. Otherwise, the future is grim for this magazine.
