From Tokyo To Coachella: YOASOBI’s Journey To Validate J-Pop And Vocaloid As Art Forms

For decades, Japanese music has been one of the hardest to access as a foreigner. Even with the popularization of cultural exports like anime and the emergence of streaming platforms, it is still considered a niche, and fans often have to dig deep in order to find albums, translations, or any kind of content at all.

"There weren’t many opportunities for Japanese music to go out into the world until now," says YOASOBI’s producer and songwriter, Ayase, over a Sunday morning Zoom from Tokyo. "If we were to break into the mainstream, I think there’s a lot more work to do. Being a part of Coachella is one of them."

The duo, composed of Ayase, 30, and vocalist Ikura, 23, is gearing up for their first performance at the mighty Californian festival next weekend, plus two sold out headline shows in Los Angeles and San Francisco. In August, they are set to play at Lollapalooza in Chicago, IL.

"Performing at festivals like Coachella was one of our goals when we put our live team together, so I believe that it will be a place for us to grow further,” says Ikura, who lived in Chicago as a kid and considers these opportunities a "full circle" moment.

Formed in 2019, YOASOBI found overnight success with their debut single "Yoru ni Kakeru," a bright-sounding but harrowing tale that topped Billboard’s Japan Hot 100 chart for six non-consecutive weeks. They continued to rise further, recording five EPs (three in Japanese, two in English), the opening theme to Netflix’s anime series "Beastars," 2021’s "Kaibutsu," and their magnum opus so far: "Idol."

Released in 2023, "Idol" became a massive hit, placing No.1 at Billboard's Japan Hot 100 chart for 22 weeks and counting — an all-time record break. It was also the nineteenth best-selling song of 2023 worldwide, according to the IFPI. With these accolades, it’s easy to understand why the duo is fully booked, but what makes their music so enticing to global audiences?

Listening to YOASOBI is like entering a rabbit hole. First, you get hypnotized by the glistening synths, bursting like fireworks, and the rock riffs taking melodies to full-speed. Then, you discover their adage is "novel into music," and all songs are based on fictional stories written by various authors. There’s also the animated music videos, each with a different style, giving their sounds another layer for interpretation. And finally, there are Ayase’s and Ikura’s (under the name Lilas Ikuta) own solo careers — treasure troves ready to be unearthed.

"I don't know, to be honest," says Ayase when asked about their growing popularity. "I guess the fact that a lot of Japanese [exports] have been prevalent around the world had to do with it. But also, maybe it's because people are experiencing this combination of music with storytelling that is interesting to them." Ikura agrees, adding that YOASOBI allows fans to "enjoy this bigger world that we are part of in a more three-dimensional way."

The experience is similar to how they create their music: mining, collecting, mixing, and transforming different threads into a new fabric. From fictional stories, Ayase transmutes his feelings into beats on his laptop with Logic Pro, then inputs melodies and lyrics through Vocaloid softwares like Hatsune Miku. Ikura listens to the Vocaloid demos, and then adds her own feelings and flair into the interpretations. For English-language tracks, they work with translator Konnie Aoki, who is "very mindful of phonetic sounds," and Ikura listens to the Japanese versions up until it’s time to record, so that she can have "the right emotions set."

It’s such a natural process for them that Ayase is surprised to know that there are still people who don’t consider Vocaloid as "real" music. “Those people probably don’t know what music is,” he says with a laugh. “Do they think that instrumental music, where there's no human singing, isn’t real music? There’s really great Vocaloid music out there, and it’s basically [voices] created through synthesizing softwares. It's very different from AI, which is auto-generated music. Vocaloid is humans creating music using these softwares. That's the only difference from a human singing a song.”

To Ikura, who maintains her burgeoning solo career in tandem with YOASOBI’s busy schedule, Vocaloid allowed her to broaden her talents. "It is my first time singing songs that somebody else wrote, so it was an opportunity to challenge myself with things that I wouldn't necessarily write, or sing in a tone or voice that I wouldn't come up with myself." She says that these experiences influence her solo works all the time, in a "synergy" that allows her to "have more colors to work with in my palette."

"I started producing music through Vocaloids,” adds Ayase. “And it truly broadened my ideas and imagination when it comes to creating music. It allows creators to come up with melodies that a human singer may not come up with. It's a fascinating culture. The possibility I feel is infinite, and it really makes the impossible possible, in a way.”

Endless possibilities are also a big allure in AI technologies, but Ayase doesn’t see this as a threat. With the right boundaries, it’s just a tool — like Vocaloid, Logic Pro, and the internet — that can be used positively. "However, as a creator myself, I really hope that creative works come out of the imagination and ideas of the human mind. In that sense, [AI] may not be 100% a positive thing for us," he shares.

But that’s something for the future. Now, YOASOBI is focusing on their very real, very tangible events ahead. "Finally, we have this opportunity where people around the world are discovering our music. So, performing at festivals like Coachella, Lollapalooza, or doing our solo shows, I think it's important that we communicate with the audiences and maximize this opportunity as much as possible," says Ikura.

And it’s not just YOASOBI getting all the attention: according to data and research company Luminate, J-pop in general is on the rise. "I’m very proud, as a Japanese person, for that situation. For us, it’s really about taking it one step at a time," says Ayase. “Our ultimate wish is to have our music or reach as many people around the world as possible, and so we will continue to work hard every day."
