Miko Koike, the last first-generation member of Sakurazaka46, officially graduated on March 20, 2025, during a heartfelt ceremony held at Makuhari Messe Event Hall in Chiba, Japan. This occasion marked the bittersweet conclusion of her decade-long journey in the idol industry, which began with her participation in Keyakizaka46.
The graduation ceremony, part of the Buddies Thanksgiving 2025 event, was the first of its kind in over two years and brought together fans and fellow members to celebrate Koike's impactful tenure. As she took to the stage after the Overture, Koike expressed her feelings with a deep bow and a smile, leading the crowd through a dynamic performance of her center song, "Sonia." Following this, she sang alongside second-generation members, showcasing a mix of heartfelt nostalgia and joy.
During her first MC segment, Koike opened up about her personal struggles with panic disorder, saying, "The ceremony has started, and while I feel a sense of sadness, I am incredibly happy to finally perform 'La vie en rose' after recording it for the first time." Her honesty resonated with fans, revealing not just her vulnerability but also how much this moment meant to her.
Additionally, Koike's performance included the collaboration with third-generation students and a powerful rendition of "Honnou," where she shared the spotlight with original center Riko Fujiyoshi. The atmosphere in the event hall shifted with their powerful vocals, energizing the audience. The highlight was a screening of cherished memories from Koike's time with Keyakizaka46, which led into her mesmerizing performance of their classic song, "Concentration." Only Koike and fellow member Yamasaki Takumi remained from the original lineup, yet they performed with confidence and nostalgia, demonstrating their growth through the years.
Each moment spent on stage was met with applause, especially as the near-end performances included the emotional "Sakurazuki" — a song that vividly encapsulated the themes of farewell and new beginnings. As the final bars of this song echoed, the audience erupted into cheers when "Ninin Saison" began, showcasing Koike at the center with her fellow second-generation members surrounding her. Koike reflected, "When I first heard 'Sakurazuki,' I felt a connection to 'Ninin Saison,' and collaborating with second-generation students was very meaningful to me. I'm grateful to have been part of this moment with you all."
As sentiments of nostalgia filled the air, Koike excitedly prompted the audience, "Buddies, let me hear your voices one last time!"— igniting a peek of excitement that crescendoed with her performance of "Nansai no Koro ni Modoritai no ka?." The show ended on a high note, with Koike and Yamasaki bringing the crowd to a fever pitch in what would be their final moment together on stage.
After an enthusiastic encore request from fans, a video montage displayed Koike's journey from Keyakizaka46 to Sakurazaka46, before she appeared in stunning white attire complete with a sparkling tiara. A warm wave of applause welcomed her as she stood before the audience, clutching a heartfelt letter she prepared for her fans and members.
Reflecting on her time, Koike said, "I have spent five years with Keyakizaka46 and five years with Sakurazaka46. Looking back, I was constantly searching for ways to contribute to the group. When our name changed, I felt like I had to carry that burden, but I realized we couldn't do it alone," she continued with palpable emotions. "The stage has always been my most honest and beloved place," she emphasized, expressing her gratitude towards her fans, or Buddies, who stood by her side throughout her journey.
In her emotional farewell, Koike addressed the newer generations, remarking, "To the third-generation students, thank you for your passion towards Sakurazaka46. Your presence has helped me learn what this group truly represents. I want to tell the second-generation students how much I admire you. You’ve helped me feel less alone after our seniors graduated."
Koike concluded with words of encouragement, saying, "Sakurazaka46 is a group without a peak in a good way. I want everyone to continue without holding back. I hope Buddies will keep watching us and supporting Sakurazaka46." Her finishing sentiments echoed throughout the venue, with heartfelt messages and flowers from members showered upon her before their final bows.
As Koike exited, she declared, "Thanks to everyone, I'm truly happy. Please continue to find happiness in your lives." This event, underpinning her journey, signifies not only an end but a new chapter, as Sakurazaka46 prepares for its next steps. With their anticipated second album, "Addiction," set to release on April 30, the fan community eagerly awaits their nationwide tour beginning April 26 in Nagoya.
