YouTube Japan Music Rankings 2025 | An Analysis of HANA, Kenshi Yonezu, and 10 Hit Songs

The 2025 Japanese music market was driven by newcomer girl groups, anime theme songs, Vocaloid creators, and viral short-form dance videos. According to the YouTube Japan annual chart summarized in the infographic, HANA’s "ROSE" took the top spot, Kenshi Yonezu saw multiple works reach the top tier, while Mrs. GREEN APPLE, DECO*27, Sakanaction, and CANDY TUNE represented different musical spheres.

The most noteworthy takeaway from this chart is not just which song placed first, but that the entry points into Japanese pop music have become highly fragmented: audition programs can manufacture new stars, anime can propel songs to a global audience, Vocaloid retains immense vitality, and short-form videos allow idol songs to spread rapidly through dance steps and catchphrases.

This article is organized based on the rankings provided in the uploaded infographic. YouTube annual charts may vary based on region, video category, statistical period, and calculation methodology; the official data released by YouTube Japan should be considered the definitive source. These rankings are not equivalent to the year-end charts of Oricon, Billboard Japan, or other streaming platforms.

YouTube Japan Music Annual Chart Top 10

1. HANA "ROSE": How audition programs create the newcomer of the year

HANA gained attention through the audition project "No No Girls." "ROSE" combines the group's origin story, member personalities, and a powerful performance, serving not just as a debut track, but as emotional gratification for viewers who followed their journey of growth.

The advantage of modern audition shows is that by the time a song is released, the audience is already familiar with the members' struggles, abilities, and relationships. When the music video drops, the view count doesn't start from zero; it builds upon the community and narrative cultivated throughout the season.

Cultural Observation: The Japanese girl group market is no longer limited to just a "polished and cute" path. HANA emphasizes individual vocal timbres, body confidence, and direct expression, reflecting a younger audience's desire for idols to retain their differences rather than being molded into a single template.

2. Kenshi Yonezu "IRIS OUT": The fusion of anime film and auteur-style singers

"IRIS OUT" continues Kenshi Yonezu's trademark high-density rhythm, bizarre timbres, and visual sensibility. When a song is linked to an anime work with a massive fan base, it generates search traffic even before the film is released; after the official release, anime viewers and the singer's fans drive traffic to one another.

Kenshi Yonezu's strength is that commercial collaborations do not erase his personal style. He is able to write easily recognizable theme songs for large-scale film projects while retaining complex arrangements, a unique vocal delivery, and a slightly unsettling worldview.

3. Sakanaction "Kaiju": The weight of a return after a hiatus

Sakanaction has long combined rock, electronic music, and dance rhythms. "Kaiju" received widespread attention not only due to its melody and visuals but also because it marked the band's major comeback after a period of activity adjustment.

The song's connection to anime culture allowed a long-established band to reach a new generation of listeners. This proves that a "comeback" in the Japanese music market doesn't rely solely on nostalgia; as long as the work can enter the contemporary media landscape, veteran musicians can successfully establish new entry points.

4. Mrs. GREEN APPLE "Darling": Writing youth anxiety into a collective consensus

In recent years, Mrs. GREEN APPLE has excelled at placing high-difficulty melodies, bright arrangements, and adolescent restlessness into a single song. "Darling" addresses emotions such as self-worth, being seen, and acceptance, making it easy to share widely across schools, social media, and among young audiences.

Bright on the surface but anxious underneath is a crucial emotional structure in contemporary J-pop. Listeners can be attracted by the melody first, then find their own insecurities within the lyrics.

5. DECO*27 "Monitoring": Vocaloid has not bowed out

"Monitoring" demonstrates that Vocaloid culture remains highly active. DECO*27 has long created music using virtual voices like Hatsune Miku, specializing in combining themes of love-related dependency, surveillance, and obsession with cute visuals, creating a contrast between sweetness and danger.

Vocaloid is not just a sound tool; it is an ecosystem where creators, illustrators, animators, cover singers, and choreographers participate together. After an original song goes viral, user-generated content extends the song's lifespan, allowing it to traverse different communities.

6. Mrs. GREEN APPLE "Kusushiki": How archaic language becomes pop music

"Kusushiki" incorporates classical and mysterious vocabulary into a modern pop arrangement. Once linked with an anime theme song setting, the work serves both the story's worldview and independent listening.

The appearance of two Mrs. GREEN APPLE songs on the same chart proves the group doesn't rely on a single hit. They can shift between youthful ballads, fantastical narratives, and large-scale collaborations while maintaining high exposure.

7. Kenshi Yonezu "Plazma": Mechanical sensations and human emotion

"Plazma" makes a distinct impression with its electronic elements, sense of speed, and sci-fi visuals. Kenshi Yonezu often places machines, the body, loneliness, and connection into the same pop song, making the work both suitable for cinematic scenes and rich in personal emotion.

For an anime tie-in song to succeed, it cannot just insert character names into the lyrics; it must translate the work's pace, conflict, and emotions into sound. This is precisely the value of auteur-style singers in cross-media collaborations.

8. Kenshi Yonezu "BOW AND ARROW": How sports anime amplifies a song

"BOW AND ARROW" uses imagery of direction, tension, and release to match themes of growth and competition. Sports anime often propel songs into high-octane highlight reels, game retrospectives, and character progression videos, resulting in continuous streaming.

With three works in the top ten, Kenshi Yonezu reflects that he is no longer just a singer who "hit it big with an anime song," but a creator who can maintain individual distinctiveness across various large-scale projects.

9. HANA "Blue Jeans": New groups need a second signature song

While "ROSE" proved HANA could make a powerful debut, "Blue Jeans" helped the group shed the risk of being seen as "only relying on audition buzz." The song's title and aesthetic carry a sense of everyday life, youth, and camaraderie, allowing the members to showcase a more down-to-earth side.

For newcomers, a second hit song is often more important than the first. A debut can rely on program buzz, but subsequent works must prove that the audience is willing to continue following the music itself.

10. CANDY TUNE "Baibai FIGHT!": The explosive power of short-form dance videos

"Baibai FIGHT!" forms numerous imitations on short-video platforms through repetitive slogans, easily remembered movements, and high-energy idol performances. The song doesn't need to be played in full; within seconds, it can establish recognizability.

KAWAII LAB., the agency behind CANDY TUNE, combines Harajuku kawaii culture, distinct member character archetypes, and social media dissemination. This model shows that today's idol songs, beyond concerts and CDs, must consider vertical videos, dance challenges, and fan-generated content.

5 major trends reflected in the 2025 Japanese music chart

1. Anime remains the global gateway for J-pop

Multiple works by Kenshi Yonezu, Sakanaction, and Mrs. GREEN APPLE reached overseas audiences through anime. With simultaneous streaming availability, anime theme songs no longer just serve Japanese television broadcasts; they are now part of a global promotion strategy.

2. Newcomers have a story before they have a song

HANA's success shows that audition programs allow viewers to establish emotional investment before debut. Newcomers are no longer just unfamiliar faces that suddenly appear in advertisements, but characters with complete narratives of growth.

3. A single creator can helm multiple major projects simultaneously

Kenshi Yonezu's multiple chart entries prove that the platform era does not necessarily fragment an artist's influence. On the contrary, creators with a distinct style who also understand cinematic narrative may secure more cross-media collaborations.

4. Vocaloid has become a cornerstone of mainstream creation

Vocaloid is no longer just an internet subculture. The model of starting from a virtual singer and branching into composition, visuals, covers, and secondary creation has deeply influenced the speed, melody, and release methods of J-pop.

5. Songs must be suitable for both "listening" and "using"

Hit songs in the age of short-form videos often need to be used for dances, edits, memes, character fan-vids, and fan support. This doesn't mean the full song is unimportant, but rather that the work has gained an additional layer of participatory function.

What are the differences between the YouTube chart, Oricon, and Billboard Japan?

Therefore, being "#1 on YouTube" does not equate to being the absolute #1 in the entire Japanese music market. Different charts measure different listening and consumption behaviors, and only by looking at them together can one understand how a song became a hit.

A song can be heard for the first time in an anime, build a fanbase through an audition story, or explode on social media because of a dance challenge. Works that truly stand the test of time are those that retain melody, character, and emotion long after the initial buzz has faded, prompting audiences to hit play again.
