His name was Jun Seba. Or, as the world would come to know him, Nujabes.
In 2010, he left this world in his thirties. Yet his music has only continued to spread across the globe since his passing. In 2018, he ranked first in the United States as the most-streamed Japanese artist overseas on Spotify. In 2022, a reworking of his music was featured in the Tokyo Paralympic Games opening ceremony. Music that began in a Shibuya record shop had quite literally reached the world stage.
What opened that path was a single anime.
The Day One Genius Found Another
Shinichiro Watanabe is a man of music. He discovered YMO as a middle school student and voraciously absorbed every genre of music he could find. Throughout the 1990s and 2000s, he visited the record shops of Shibuya's Udagawacho nearly every week, checking every new release he could get his hands on. In an interview with ARBAN ( https://www.arban-mag.com/article/55072 ), he said:
"I was a regular at record shops, so I'd listened to all of his early 12-inch singles. The sampling sources were distinctive, melodic, with this unique lyricism of his — I could see images forming in my head."
At the time, Nujabes was an unknown beatmaker releasing 12-inch singles on his own label, Hydeout Productions, within Shibuya's underground scene. He hadn't even revealed his nationality. Virtually no one in the mainstream knew who he was.
Watanabe, who sensed "images forming" within that music, chose Nujabes to score the 2004 TV anime Samurai Champloo. In the same interview, Watanabe also said:
"I wanted to elevate the music, to have it compete with the visuals at a 50:50 level — sometimes I even wanted the music to overpower the images. For that, I needed music with that kind of force. Within hip hop, Nujabes was the best fit."
One genius found another. A director who had been digging through 12-inch records in Shibuya's shops became convinced that the music of a beatmaker running his own shop in that same neighborhood was exactly what he needed. When genius recognizes genius — that moment became the starting point of a global movement.
When Period Drama Collides with Hip Hop
Samurai Champloo is a work that blends Edo-period period drama with hip hop culture — graffiti, breakdancing, and beats. The title "Champloo" comes from the Okinawan word for "mixed up." True to its name, this seemingly impossible combination clicks together miraculously.
The music featured four beatmakers alongside Nujabes: fat jon, FORCE OF NATURE, and Tsutchie. Among them, the tracks Nujabes created — "battlecry feat. Shing02," "aruarian dance," "mystline" — with their lyrical beats built on jazz and soul samples, resonated perfectly with the loneliness of samurai and the melancholy of the journey.
The show was far from a massive hit during its original Japanese broadcast. But through reruns in the United States, its fanbase grew steadily. As Watanabe himself recalled, "When I go to anime events in America, these big intimidating Black guys come up and say 'Can I get your autograph?' When I ask 'Which show do you like?' they say 'Samurai Champloo.'" The series struck a deep chord, particularly with audiences connected to hip hop culture.
The "Godfather" of Lo-Fi Hip Hop
It was after his death that Nujabes's music began to be discussed in an even larger context.
Lo-fi hip hop — the mellow, chill beats that stream quietly on 24-hour YouTube channels — became a global movement from the mid-2010s onward. As one of its foundational figures, Nujabes came to be called a "godfather" alongside America's J Dilla.
In the same ARBAN interview, Watanabe reflected on this movement:
"The people making lo-fi were watching anime when they were kids. Childhood experiences leave such strong impressions — so as they dug into music from there, maybe that's how the lo-fi hip hop movement was born."
In other words: Shinichiro Watanabe discovered Nujabes in a Shibuya record shop and brought his music into anime. That anime aired in America, and Nujabes's sound reached the ears of children. Those children grew up, dug into Nujabes's catalog, absorbed its influence, and created an entirely new genre called lo-fi hip hop. One director's instinct that "this music is something special" rewrote the global music map twenty years later.
To the Genius No Longer Here
Nujabes is no longer in this world. His death came far too soon. Yet his comrades completed his third album, Spiritual State. Memorial events were held. The soundtracks celebrated their 20th anniversary with analog reissues. The four vinyl titles released in 2022 became an exceptional hit, selling over 30,000 copies combined. In 2024, his music was finally made available on streaming services.
If he were still alive today, what kind of music would he be making? Perhaps, like Kamasi Washington on LAZARUS, he would have scored anime himself. Or perhaps he would have created music in an entirely different dimension. We will never know.
But one thing is certain. An unknown beatmaker who had been pressing 12-inch singles in Shibuya's Udagawacho was carried out into the world by anime — a vessel for stories. And that music continues to be played around the world, even after its creator is gone.
When genius reaches the world, it was another genius who opened the door. If Shinichiro Watanabe hadn't sensed "images forming" in Nujabes's music, Samurai Champloo would never have been born. Without Samurai Champloo, lo-fi hip hop might have taken a different shape entirely. Genius recognizes genius. That chain of encounters moves the history of music.
Anime music carries that kind of power. Music combined with story can change an artist's life, birth an entire genre, and repaint the landscape for listeners around the world. We are standing witness to a place where such miracles happen.
