Kusumi Koharu (久住小春) was born on July 15, 1992 in Nagaoka, Niigata, Japan. She is a former member of Morning Musume and Hello! Project. She was also a voice actress for the anime Kirarin Revolution. She is currently a CanCam model and a member of Dream Morning Musume. She joined Morning Musume as the only seventh generation member and as the youngest soloist to debut in Hello! Project, being only twelve years old when she joined. Before she joined Morning Musume, she was the captain of her school's volleyball team. Kusumi's audition process and debut was documented during the 2005 episodes of TV Tokyo television show, Hello! Morning.

As a Hello! Project soloist, her highest selling single is Balalaika with 72,709 copies. Her lowest selling single is Hapi☆Hapi Sunday! with 14,468 copies sold.



Kusumi Koharu joined Morning Musume in 2005 as the only seventh generation member.


Kusumi has been a member of the Hello! Project kickball team Metro Rabbits H.P. since its formation in the beginning of 2006. Since April 7, she has been the voice actress for Kirari Tsukishima, the main character in the anime Kirarin Revolution.


In early 2007, Kusumi was chosen to be a member of Morning Musume Tanjou 10nen Kinentai— a unit created to celebrate Morning Musume's 10th anniversary as a group. Morning Musume Tanjou 10nen Kinentai also consisted of Iida Kaori, Abe Natsumi, Goto Maki and Niigaki Risa. Their first single, "Bokura ga Ikiru MY ASIA", was released on January 24, 2007.


Apart from her activities in aforementioned units, Kusumi is also a member of Kira☆Pika with ℃-ute's Hagiwara Mai and MilkyWay with Hello! Pro Kenshuusei members Kikkawa Yuu and Kitahara Sayaka. Both units were formed for the Kirarin Revolution anime, which ended in March 2009. Kusumi is currently a regular on the TV Tokyo children's show Oha Suta, appearing every Tuesday.

In 2009, Kusumi was assigned to be a part of the new shuffle group, ZYX-α along with Niigaki Risa, Umeda Erika, Ogawa Saki, Wada Ayaka, Tsugunaga Momoko, Tokunaga Chinami, and Sudo Maasa.

After the first performance at Morning Musume's 2009 Fall Tour Nine Smile, a shocking announcement was made that Kusumi would graduate from Morning Musume and Hello! Project in December 2009. According to the official announcement, she was planning to be a model, similar to Umeda Erika (℃-ute)'s graduation purpose.

Her graduation marked the end of the longest stable lineup of Morning Musume (the group had gone just over two years without any change in membership, the longest in its history), as it was the first change in the group's roster since the departures of Yoshizawa Hitomi and Fujimoto Miki in 2007.
