When YOASOBI vocalist ikura and composer Ayase sat down with actress Shizuka Ishibashi for their first conversation together, the meeting brought together three artists who had been working on different sides of the same creative project: NHK's 115th serial television novel, Blossom (ブラッサム). A special program aired on November 3, 2026, giving us an intimate look at how the duo created "Sakihokore" (咲き誇れ), the drama's theme song, and revealing just how deeply the collaboration affected everyone involved.
We now have a clearer picture of the creative process behind one of YOASOBI's most emotionally charged projects to date, and the connection between the song and the drama it accompanies runs deeper than many of us might have expected.
The Quick Version
- YOASOBI created "Sakihokore" ("Bloom Gloriously") as the theme song for NHK's morning drama Blossom, which began broadcasting on September 28, 2026
- The special program "How the Theme Song for the Serial Television Novel 'Blossom' Was Made" aired on November 3, 2026, at 8:15 a.m. on NHK General TV
- This marked the first time ikura and Ayase spoke directly with lead actress Shizuka Ishibashi about the project
- The song was released digitally on October 14, 2026, with its full-length version and music video
- Ishibashi reportedly kept the song's lyrics posted in her dressing room throughout filming for encouragement
What Blossom Is Really About
To understand why "Sakihokore" sounds the way it does, we need to understand the drama it was written for. Blossom is an original work by screenwriters Tsuyoshi Sakurai and Yoshiko Komatsu, inspired by the life of writer Chiyo Uno. The story follows Tama Hano, a woman whose life spans four distinct eras of Japanese history: Meiji, Taishō, Shōwa, and Heisei.
What makes Tama's story compelling is the journey itself. She faces hardship after hardship across these decades of tremendous social change, yet the narrative arc is ultimately about blooming and flourishing despite everything that tries to hold her back. It's a story about resilience that stretches across generations, and that theme of eventual flowering after struggle gave YOASOBI the emotional core they needed to craft the theme song.
How YOASOBI Approached Their First Morning Drama Theme
Creating a theme song for an NHK morning drama represents a significant milestone for any Japanese artist. These dramas are cultural touchstones, watched by millions every morning, and the theme songs often become part of the national soundtrack for the months they air. For YOASOBI, this was their first opportunity to create music for this particular format, and they approached it with careful consideration.
According to official statements from the program, Ayase described "Sakihokore" as a song about "crossing a turning point in life." This wasn't just a catchy pop song designed to wake people up in the morning; it needed to capture the emotional weight of a woman's century-spanning journey. The creative challenge was to distill that massive narrative scope into a few minutes of music that would resonate with viewers every single morning.
ikura's approach to the vocals was equally intentional. She stated that she sang with "200%" of her feelings, pouring everything into a performance that could match the emotional stakes of Tama's story. When we hear the song, we're hearing a vocalist who understood that she was giving voice not just to a character, but to a theme of perseverance that would accompany viewers through their own daily lives.
The Emotional Impact on Shizuka Ishibashi
What makes the November 3 special program particularly revealing is how it showed us the effect YOASOBI's work had on the person actually embodying the story. Shizuka Ishibashi's connection to "Sakihokore" went beyond simply hearing a theme song for the show she was starring in. During the filming of Blossom, she reportedly kept the lyrics posted in her dressing room.
Think about what that means for a moment. An actress in the middle of a demanding, long-running role chose to surround herself with these particular words as a source of encouragement. The lyrics weren't just accompanying her performance; they were sustaining her through the work itself. When Ishibashi finally met ikura and Ayase during the special program, the encounter moved her deeply. A surprise from the duo during the filming brought her to tears, suggesting that the collaboration had created an emotional bond even before the three had spoken face-to-face.
The Creative Influence of the Drama on the Song
The special program explored how multiple aspects of Blossom influenced YOASOBI's creative process. It wasn't just the script that shaped "Sakihokore." The show's visual identity, Ishibashi's interpretation of Tama, and even the historical sweep of Chiyo Uno's life all fed into how Ayase composed the music and how ikura approached her vocal performance.
This kind of deep integration between a drama and its theme song creates something richer than we often get from more transactional collaborations. YOASOBI wasn't working from a brief or a pitch deck; they were responding to a living, evolving creative work. The fact that the program dedicated thirty minutes to exploring this process tells us that NHK recognized something special was happening in how these artists were connecting across their different mediums.
Where You Can Experience "Sakihokore"
If you want to hear the full version of "Sakihokore," it became available digitally on October 14, 2026. The music video was also released on that date, giving fans a visual interpretation to accompany the audio.

The special program itself aired on November 3, 2026, from 8:15 to 8:45 a.m. on NHK General TV, offering that rare behind-the-scenes look at how a theme song and a drama can shape each other.
