On July 20, 2026, Ayase — the composer and producer half of the chart-topping Japanese duo YOASOBI — shared a candid reflection on the toll that seven years of relentless success has taken on his personal life and health. In a detailed interview, he revealed that his "daytime face had disappeared," a poignant metaphor for how completely his work had consumed his normal life, and explained his decision to prioritize his health through significant weight loss. For those of us who've watched YOASOBI's meteoric rise since 2019, Ayase's reflections offer a rare, honest look at what it takes to sustain creativity at the highest level — and what sometimes gets lost along the way.
We're taking a closer look at what Ayase shared about his journey: the weight loss numbers that have surprised fans, what he means by losing his "daytime face," and how he's working to rebuild a healthier balance after years of non-stop work.
The Quick Version

- Ayase lost approximately 19 kg (about 42 pounds) over the course of a year, motivated primarily by health concerns rather than appearance
- He described feeling that his "daytime face had disappeared" over seven years of intense work, a lifestyle he now recognizes as unhealthy
- Earlier weight-loss efforts included dropping 7-8 kg in three weeks during YOASOBI's 2023 arena tour, and in early 2025 he shared on Instagram that he'd lost 14 kg since the start of that year
- The interview, published on July 20, 2026, marks a moment of reflection roughly seven years after YOASOBI's breakthrough
- Ayase's focus has been on training and structured eating to live "as healthily as possible" while maintaining his demanding creative schedule
What "My Daytime Face Had Disappeared" Really Means
When Ayase says his "daytime face" vanished, he's describing something many of us in demanding careers can relate to: the complete erosion of normal life rhythms in pursuit of success. In his own words from the interview, he felt that over these seven years, his daytime persona or everyday life had essentially disappeared because of his work schedule and lifestyle. He explicitly called this state "a bit unhealthy."
What does that look like in practice? For a music producer and performer at YOASOBI's level, it likely means working through the night in the studio, sleeping during the day, and losing touch with the basic structure most people take for granted — meals at regular times, daylight hours spent with friends or family, a clear boundary between work and personal time. When your creative process operates on its own clock and global tour schedules dictate your calendar, the "normal" parts of life can slip away almost without you noticing.
Ayase's reflection carries weight precisely because it's not a complaint but an acknowledgment. He's looking back on the price of the extraordinary success YOASOBI has achieved since their 2019 debut, when "Yoru ni Kakeru" ("Racing Into the Night") became a phenomenon. Seven years later, with international tours, chart-topping releases, and a fanbase spanning continents, he's recognizing that something important was sacrificed along the way — and he's actively working to reclaim it.
The Timeline of Ayase's Weight Loss Journey
Ayase's approach to regaining his health has unfolded in several distinct phases, each reflecting different priorities and circumstances in his career. The most significant effort came during the year leading up to his July 20, 2026, interview, when he lost approximately 19 kilograms. In his own words, he made a serious commitment to diet "for his health" and managed to shed about 42 pounds over twelve months.
This wasn't his first round of focused weight management, though. During YOASOBI's 2023 arena tour — specifically the "Denkou Sekka" ("Lightning Speed") tour — Ayase noticed his weight had increased under the pressure of constant performances and travel. He responded with an intensive three-week training regimen that resulted in a loss of 7-8 kg. At that time, he told interviewers he was being careful about his diet, often eating only fixed, routine meals, and felt he was finally living "as healthily as possible."
Then, in early 2025, during YOASOBI's Hall Tour "WANDARA," Ayase shared a mirror selfie on Instagram (later deleted) revealing he'd lost 14 kg since the beginning of that year and planned to cut an additional 2-3 kg. Fans noticed his visibly leaner physique and praised his dedication, with many describing his appearance as "stoic" and noting his lean, toned build.
What emerges from this timeline is a picture of sustained, intentional effort rather than a quick fix. We're looking at someone who recognized a problem, committed to addressing it in stages, and has maintained that focus even as his career demands have only intensified. The consistency is striking — and it underscores how seriously Ayase has taken his own health warning signals.
Why Health, Not Appearance, Drove the Change
It's worth emphasizing what Ayase himself stressed in the interview: his weight loss was fundamentally motivated by health concerns, not aesthetic goals. In an industry where image often drives everything, that distinction matters. Ayase made it clear that he wasn't trying to achieve a particular look for the stage or for social media — he was responding to the recognition that his lifestyle had become genuinely unhealthy.
The way he approached the weight loss reflects that priority. Rather than crash diets or extreme measures, he focused on training, structured eating, and building sustainable habits. During the 2023 arena tour period, he mentioned eating routine, fixed meals — the kind of discipline that creates consistency rather than drama. The longer, 19 kg loss over a full year suggests a steady, measured approach: roughly 1.5 kg per month, which falls well within what health professionals consider safe and sustainable.
We can understand this shift as part of a larger recalibration. Ayase isn't just trying to lose weight; he's trying to rebuild a life structure that allows for longevity in his career. Seven years of operating at YOASOBI's intensity is a marathon, not a sprint, and he seems to have realized that maintaining that pace requires taking care of the fundamentals — sleep, nutrition, physical fitness, and mental space.
YOASOBI's Seven-Year Journey to This Reflection
To fully appreciate what Ayase is reflecting on, we need to understand just how transformative these seven years have been. YOASOBI burst onto the scene in late 2019 with "Yoru ni Kakeru," a song that wasn't just a hit — it redefined what Japanese pop music could sound like and how it could reach audiences. The duo's concept, turning novels and stories into songs, captured something special, and their blend of electronic production, soaring melodies, and vocalist Ikura's distinctive voice created an instantly recognizable sound.
What followed was the kind of success that changes everything. International tours, collaborations with major brands and anime productions, millions of streams, and a level of recognition that took YOASOBI from internet sensation to cultural phenomenon. For Ayase, as the composer and producer, this meant an unrelenting creative output — new songs, arrangements for live performances, production work, and the constant pressure to maintain the standard they'd set.
Success at that level doesn't come with an off switch. There are always more opportunities, more demands on your time, more expectations to meet. We can see how, year after year, the work could expand to fill all available space — and then some. The "daytime face" disappears because there's always another track to finish, another performance to prepare for, another deadline to meet. The reflection Ayase shared on July 20, 2026, marks a moment of looking back and asking whether the pace is sustainable — and what needs to change to make it so.
The Broader Picture: Balancing Art and Well-Being
Ayase's story resonates beyond YOASOBI's fanbase because it touches on something many of us grapple with: how do you maintain your health and personal life when your work demands everything you have? For creative professionals especially, the boundary between work and life often dissolves completely. The studio is always there, the ideas don't stop at 5 PM, and the pressure to capitalize on success can make it feel impossible to step back.
What Ayase is modeling, in sharing these reflections, is a kind of honesty that we don't always see from public figures at the height of their careers. He's not pretending everything has been perfect or that success came without cost. He's acknowledging the trade-offs, examining what he's lost, and actively working to restore balance. That's valuable not just as a personal narrative but as a reminder that even extraordinary success requires periodic reassessment.
We're also seeing him make deliberate choices to prioritize long-term sustainability over short-term intensity. The weight loss isn't about a quick transformation; it's about building habits that will support him through the next seven years and beyond. The recognition that his lifestyle had become unhealthy is the first step toward changing it — and by making that recognition public, Ayase is helping to normalize conversations about well-being in an industry that often glorifies overwork.

Ayase made it clear in his interview that his primary motivation was health, not appearance.
