Statement from Yokoyama Reina[29]
To everyone who has always supported us:


I will be graduating from Morning Musume。'25 and Hello! Project after the 2025 fall concert tour.

It's been about eight and a half years since I joined Morning Musume。, and during that time I've had countless precious experiences. I've made it this far thanks to the warm love and support from the members and all of you. Thank you so much for always being there for me.

Morning Musume。is a group that continues to evolve through the graduations and additions of its members. As I watched my seniors graduate one by one, I began to think more deeply about my own future over the past few years.

I've always been the type of person who gets curious about many things and immediately thinks "I want to give it a try!" So the vision of a fun future in my mind kept expanding.

As a person, I want to open the door to freedom! I want to live true to myself and pursue what I truly want to do! That feeling is now stronger than ever, and I'm truly excited and looking forward to it.

After graduation, I will be ending my entertainment activities and starting a new path. I'm really looking forward to what lies ahead for me and my future!

From the 15-year-old me back then to the 24-year-old me now, I'm filled with gratitude to everyone who has supported me, and to all the people I've met along the way. Those encounters are lifelong treasures to me!

Although there isn't much time left, I will continue to express my gratitude as Yokoyama Reina of Morning Musume。If you could stay with me until the end, I would be so happy.

Morning Musume。'25
