With so many new anime arriving every year, some series eventually disappear from conversations even when they had good stories, memorable characters, and unique concepts. Some were popular during certain periods, others built a loyal following, and there are those that simply seem to have been left behind by time.
That is why we have put together 5 good anime that were forgotten over time. The list covers different generations, from 1990s classics to a relatively recent series that eventually lost its place among the major titles discussed by fans.
1. The Law of Ueki
Episodes: 51
Where to watch today: Crunchyroll, depending on the region
The Law of Ueki is one of those action anime that seem to have been erased from the collective memory. The series follows Kousuke Ueki, a student who receives the power to turn trash into trees and ends up involved in a competition between users of supernatural abilities.
The concept may seem strange at first, but that creativity is exactly what made the series stand out. The battles did not rely solely on brute force: the characters had to understand the limitations of their powers and find clever ways to use them.
With its 51 episodes, the series had enough room to develop its characters and build different battles. Even so, when people talk today about major 2000s shonen anime, The Law of Ueki is often left out of the conversation. Perhaps that is precisely why it deserves to be remembered again.
2. Tenchi Muyo! Universe
Episodes: 26
Where to watch today: availability varies by country
Tenchi Muyo! Universe belongs to an era when television helped introduce a large number of Japanese anime to international audiences. The series blends comedy, science fiction, romance, and adventure around Tenchi Masaki and a group of characters who turn his life into complete chaos.
What makes it particularly interesting is that Tenchi Muyo! came before many of the titles that later popularized similar elements within romantic comedies and harem anime.
Today, however, it is much less common to find Tenchi Muyo! on recommendation lists for new fans. The franchise itself has several series and continuities, which can also make its legacy more difficult to follow.
For those who enjoy classic 1990s anime, Tenchi Universe remains a series worth rediscovering.
3. Shinzo
Episodes: 32
Where to watch today: limited legal availability; may vary by region
If there is one anime that perfectly fits the idea of “do you remember this anime?”, it is Shinzo.
The story follows Yakumo, a human girl who awakens hundreds of years after being placed in cryogenic sleep. The world she finds is completely different: humanity has almost disappeared, and creatures known as Enterrans have taken over the Earth.
Yakumo then sets out in search of the last surviving humans, with the help of Mushra, Sago, and Kutal.
The combination of adventure, science fiction, fantasy, and action gave the series its own identity. The anime also features a particularly interesting post-apocalyptic premise for a production aimed at younger audiences.
Despite this, Shinzo has become largely absent from current discussions about major anime from the early 2000s.
And perhaps that distance is exactly what makes rediscovering it so much fun.
4. Bucky/Jibaku-kun
Episodes: 26
Where to watch today: legal availability may vary by region
Bucky, originally known as Jibaku-kun, is probably one of the best examples of an anime that can trigger an instant memory in people who grew up watching Japanese animation on television.
The story presents a world divided into different territories, where the so-called Great Children are responsible for protecting their inhabitants. Bucky dreams of becoming the ruler of the world and embarks on a journey across different lands.
The anime combines adventure, fantasy, comedy, and battles, while also featuring a distinctive aesthetic characteristic of anime from the late 1990s.
What is interesting is that Bucky managed to leave an impression on part of its audience at the time, but today it is much less remembered compared to other classic 1990s anime. That contrast is exactly what makes Bucky a perfect choice for this list.
5. Radiant
Episodes: 42
Where to watch today: Crunchyroll, depending on the region
Not every forgotten anime has to be old. Radiant shows that even a relatively recent production can quickly disappear from conversations.
Based on the French comic created by Tony Valente, the anime follows Seth, a young sorcerer who wants to find Radiant, the supposed birthplace of the Nemesis, creatures that fall from the sky and spread destruction.
With elements of fantasy, adventure, and shonen, Radiant has a distinctive identity within Japanese animation. The series also stands out for adapting a story originally created outside Japan.
The anime had two seasons and 42 episodes and received a Brazilian Portuguese dub, even reaching Cartoon Network's Toonami block in 2021. Despite receiving this international exposure, Radiant became less present in discussions about the major anime of the last decade.
This makes it an interesting case: it may not exactly be an unknown anime, but it is certainly a series worth remembering for anyone looking for something different from the most popular titles.
Why Were These Anime Forgotten?
There is one characteristic these five series have in common: none of them needs to be considered an unknown anime to be included on this list.
What happened was different. The anime market grew, new platforms emerged, and the number of releases increased considerably. As a result, many series that had their moment eventually lost space to more recent productions.
The Law of Ueki, Tenchi Muyo! Universe, Shinzo, Bucky, and Radiant represent different moments in this history. Some belong to the television era, while others arrived during a time dominated by streaming.
Perhaps the most interesting part is discovering just how many of these series can still surprise viewers who decide to watch them today.
Do You Remember These Anime?
Some anime disappear because they were not successful. Others simply get pushed aside when a new generation of series emerges. But being less remembered does not necessarily mean that a series has lost its value.
Which of these anime have you watched? Is there another forgotten anime that should appear on a future list?
