Banned, censored and erased: 5 anime titles that became too controversial for the world to ignore

Anime has never been afraid to go where mainstream animation often refuses to tread. From extreme gore and disturbing psychological themes to controversial sexual content and explosive social commentary, some Japanese animated titles have pushed censorship authorities to their limits.

While many controversial anime merely spark online debates, others have faced something far more serious: official bans, refused classifications, distribution blackouts, and international cancellations.


Here are five controversial anime and animated titles that faced restrictions, bans, or international backlash across multiple countries.

Few anime have developed a reputation as infamous as Violence Jack. The OVA adaptation of Go Nagai's manga is notorious for its extreme brutality, graphic gore, and disturbing depictions of sexual assault. Its unapologetically violent content quickly made it one of the most controversial anime titles ever released.

The anime became particularly controversial during the United Kingdom's infamous "video nasties" era. Several episodes were denied classification, meaning they could not legally be sold, imported, or distributed through official channels.

Its reputation has endured for decades. Even now, Violence Jack remains one of the most extreme examples of anime pushing the boundaries of censorship and acceptable screen content.


If there is one title that helped challenge the idea that animation was automatically meant for children, it is Urotsukidōji: Legend of the Overfiend.

The film combined graphic violence, body horror, explicit sexual content, and deeply disturbing imagery. Its controversial material resulted in heavy censorship in the United Kingdom, where the film was released only after significant edits. Other countries took an even stricter approach and banned the title altogether.

The controversy surrounding Urotsukidōji had an impact beyond the film itself. Its release forced regulators to confront a growing reality: Japanese animation could be created specifically for adults and could contain material just as extreme as live-action films.

The title became one of the works that pushed several countries toward more specialized classification systems for adult-oriented animation.

Few anime have generated as much discomfort and debate as Kodomo no Jikan. The series focuses on elementary school students while incorporating suggestive situations and themes that made it extremely controversial.

Although its creators have maintained that the story was intended to explore psychological and social issues, its presentation led to intense scrutiny. The controversy was so severe that several distributors avoided releasing the series altogether.


In Australia, the Classification Board refused classification for certain versions of the manga, while the anime also faced significant attention because of its sensitive subject matter.

Even among anime fans who typically oppose censorship, Kodomo no Jikan remains a difficult title to defend or approach. Its subject matter placed it firmly in one of anime's most controversial categories.

Unlike many titles on this list, High School DxD is a hugely popular anime with a global fanbase. However, its popularity did not prevent one of its OVAs from facing an official ban.

In 2015, New Zealand's Office of Film and Literature Classification refused to classify High School DxD New: Oppai, Tsutsumimasu!. Authorities argued that the OVA sexualized characters who appeared underage, putting the title in conflict with local legal standards.

As a result, the OVA could not legally be distributed or circulated in New Zealand. The decision remained in place for years before the ban was lifted in 2023 following a review. The title was subsequently classified R16.

Despite the eventual change in classification, the incident remains unusual because it involved a globally successful and mainstream anime franchise rather than an obscure underground title.

Unlike many controversial anime criticized for graphic violence or explicit content, Death Note faced backlash over fears that its fictional premise could inspire real-world behaviour.


After the manga and anime became global hits, schools in China, the United States and parts of Southeast Asia reported incidents involving students creating notebooks inspired by the series' supernatural "Death Note." Some reportedly wrote the names of classmates or teachers inside them, imitating the central concept of the franchise.

The incidents raised concerns among educators, leading several schools to ban Death Note manga, related merchandise and imitation notebooks from their campuses.

The controversy intensified in 2015 when China's Ministry of Culture placed Death Note on its list of anime prohibited from domestic online platforms and also restricted the sale of related merchandise.

Unlike most anime controversies, the backlash surrounding Death Note focused less on its on-screen content and more on fears that its fictional concept could influence younger viewers and encourage copycat behaviour.
