A debate over the influence of anime tie-ins on contemporary J-pop has been unfolding online after a post by music commentator Mino Music drew more than 4 million views on X, prompting responses from across the music and anime industries.
Published on March 10th, Mino’s essay “Is J-POP Becoming a Subcontractor for Anime?” argues that tie-ins have become so dominant that songs are increasingly evaluated through the stories they accompany rather than discussed purely as music.
Mino pointed to chart performance as one indication of how central tie-ins have become in the industry. Eight of the top ten songs on Billboard Japan’s 2025 year-end Hot 100 were tied to anime, film, or television, with only two songs lacking a media tie-in. In his view, this illustrates a market in which songs breaking through without some form of media attachment have become increasingly rare, with tie-ins affecting not only promotion but also how music is commissioned and evaluated.
Examples from the chart include Mrs. GREEN APPLE’s ‘Lilac’, used as the opening theme for the anime Oblivion Battery, Kenshi Yonezu’s ‘IRIS OUT’, tied to Chainsaw Man – The Movie, and Sakanaction’s ‘Kaiju’, the theme for Orb: On the Movements of the Earth.
The essay further suggests that modern tie-ins are often expected to show a close interpretive relationship with the original work, with “faithfulness” increasingly treated as a standard in itself. Mino also points to the 89-second format of anime openings and endings as a structural constraint, arguing that its influence now extends beyond official tie-ins, with songs written in “anime size” increasingly feeding back into the wider J-pop market.
In response, music producer and critic Akimitsu Tomita said that music has always been impacted by outside forces, including context, narrative, media, and delivery formats. He added that anime now functions as part of the infrastructure supporting Japan’s music industry and remains a key route through which domestic artists reach overseas listeners.
Others pushed back more directly on the framing of the piece, arguing that it gave the impression anime was being placed below music as an art form. Critics also took issue with the title itself, saying collaboration between anime and music should not automatically be treated as a problem.
Some have also pointed out that the 89-second structure of anime openings is only one of several external pressures affecting modern pop songs. Music journalist Patrick St. Michel noted that while the format can influence song construction, it remains relatively flexible compared with the far tighter structural expectations often placed on music designed for short-form platforms such as TikTok.
Musician and producer Yamato Kasai noted in a series of posts that theme-song production differs widely depending on the setup, with some projects requesting close alignment with a work and others leaving artists far more freedom. He argued that treating all tie-ins as if they operate under the same conditions flattens a more complicated reality.
One of the clearest factual corrections came from Fullmetal Alchemist director Seiji Mizushima, after Mino referenced ASIAN KUNG-FU GENERATION’s ‘Rewrite’ as an example of an earlier tie-in era. Mizushima said the article misunderstood how the song was selected, explaining that ‘Rewrite’ was not written specifically for Fullmetal Alchemist but was suggested when its release timing happened to align with the series.
“Fortunately, the release timing happened to line up, and a producer from the label approached me saying, ‘ASIAN KUNG-FU GENERATION’s release fits the timing, so please listen to the song!'”.
He added that, in his view, tie-in songs should still have enough artistic identity to stand apart from the anime.
ASIAN KUNG-FU GENERATION frontman Masafumi Gotoh wrote on X that many rock bands were hesitant about anime theme songs in the early 2000s. According to Gotoh, artists could face dismissive comments or be labelled an “anime song band”, a tag some groups tried to avoid.
He said the band wrestled with the decision when ‘Haruka Kanata’ was selected as an opening theme for Naruto, but ultimately accepted because they believed anime could help their music reach audiences overseas.
“Back around the time of ‘Haruka Kanata’, many rock bands were not very enthusiastic about anime tie-ins”, he wrote. “There were insults and snide remarks like calling someone an ‘anime song band'”.
「遥か彼方」の頃は、ロックバンドの多くはアニメタイアップについてあまり積極的ではなくて、「アニソンバンド」みたいな悪口や陰口もあって、現在みたいな状況ではなかったと記憶しています。僕らも当時随分悩んで、アニメと共に「世界に出る」その可能性を信じて引き受けました。放送ではイントロが…

Gotoh said the scale of the response only became clear years later as the series gained global popularity. Today, he added, the song draws strong reactions from audiences around the world.
Some artists have been more direct in rejecting the “anime band” label. Metalcore band SiM achieved a global breakout with ‘The Rumbling’, used in Attack on Titan: The Final Season in 2022, but frontman MAH has said the band does not want to be pigeonholed by that association, even telling overseas audiences early in the band’s international touring that SiM are “more than just an anime song band”. In a 2024 interview with Metal Hammer, he acknowledged that the song brought many anime fans to SiM but said the group ultimately hopes to reach “rock fans and not just anime fans”.

Anime’s global expansion in recent years has reinforced its role as one of the most visible entry points for Japanese music overseas. The medium brings with it a highly engaged international fan base that actively supports the wider ecosystem around a series, from streaming and social media sharing to merchandise and live events. For decades the relationship has worked as a mutual exchange: anime gains memorable opening and ending themes, while artists gain exposure to audiences far beyond Japan’s domestic market.
However, some industry figures warn that relying too heavily on this route can also limit how those artists are perceived abroad.
In a 2025 interview with Music Business Worldwide, Universal Music Japan CEO Naoshi Fujikura said that while anime can help “bridge Japanese artists onto the global stage”, “once you position an artist as an ‘anime artist’, it becomes very difficult to develop their career beyond that”, adding that the goal is to create “absolute stars, not just anime hit artists”.
Industry data also highlights how strongly Japanese music exports remain tied to those ecosystems. A 2024 report by Japan’s Ministry of Economy, Trade and Industry found that roughly 60% of the songs in Spotify Japan’s “Japanese Songs Heard Abroad” rankings between 2017 and 2023 were connected to anime, manga, or video games.
Streaming platforms, however, say the audience for Japanese music is beginning to widen. Spotify said in May 2025 that Japanese music is reaching listeners worldwide “well beyond the traditional gateway of anime”. At the same time, anime-related music continues to grow rapidly, with Spotify reporting that global streams of anime music have risen 395% since 2021.
Some observers, however, question whether the prominence of anime tie-ins necessarily means they are changing the sound of J-pop itself. Recent theme songs often draw from the same stylistic range already present in Japanese pop. Artists such as YOASOBI, Creepy Nuts, and Kenshi Yonezu have all released anime-linked tracks that continued to perform strongly long after their associated series finished airing. Their success suggests anime can amplify songs that already stand out, rather than flattening artists into a single recognisable formula.
Mino’s essay has prompted some of the most nuanced discussion in years about the relationship between Japanese pop and visual media. For decades, the industry has developed alongside television, film and animation, and many of the country’s most widely recognised songs emerged from those links. What has changed is less the existence of tie-ins than the scale of the global ecosystem around anime and the international routes it now provides.
The debate also points to a broader question about how Japanese music develops within an entertainment industry built on collaboration. Anime may sit at the centre of that network right now, but there is still little agreement on whether its influence amounts to a creative opportunity, a commercial necessity, or simply the latest phase in J-pop’s long relationship with other forms of media.
