Kanae Yoshii, a member of 9nine, has announced that she has left the group.
The singer made the announcement through the group's official website.
"I want to sing music, but my heart just isn't in it," Yoshii said.
9nine suspended its activities in April to allow its members to work on their personal activities, try new things, and grow.
With Yoshii's withdrawal, 9nine is now a 3-member group consisting of Sayaka Nishiwaki, Uki Satake and Hirona Murata.
There is no set time for 9nine to resume its activities.
