Early LifeEdit

Kosuga Fuyuka was born on November 19, 1997 in Kanagawa, Japan.

Prior to auditioning for S/mileage, she had previous experience in the entertainment industry.[citation needed]


In 2011, Kosuga auditioned for S/mileage Shin Member Boshuu! and successfully passed. She was introduced as a S/mileage sub-member on August 14 along with Nakanishi Kana, Takeuchi Akari, Katsuta Rina and Tamura Meimi.

On September 9, Kosuga was diagnosed with severe anemia and as a result left S/mileage after only 26 days. It was announced on S/mileage’s official site that Kosuga will be leaving S/mileage due to her anemia, and would later on join Hello Pro Kenshuusei after her recovery. According to the site's announcement, Kosuga had been feeling bad and was immediately transferred to the hospital because of her terrible condition. The promotional events for S/mileage's single "Tachiagirl" and their fall concert tour had to undergo some changes because of her loss.


In January, Kosuga returned to Hello! Project by joining Hello Pro Kenshuusei alongside Uemura Akari.[1] Her return was not revealed until March 13, when a picture was released with ℃-ute's Okai Chisato and the rest of Hello Pro Kenshuusei, which included Kosuga herself.

In March, Hello Pro Kenshuusei had a concert and Fuyuka made her official return to Hello! Project.

In June, it was revealed that she had auditioned for Morning Musume's 11th Generation, but failed to pass.

On March 31, when the news about the May Kenshuusei event, "Hello Pro Kenshuusei Happyoukai 2013 ~Haru no Koukai Jitsuryoku Shindan Test~", was released, it contained Kosuga's name as one of participating members, confirming her return.


On January 30, the Kenshuusei appeared in Gekkan Entame magazine, and it was briefly reported that Kosuga was in poor physical condition.

On May 4, at the Hello Pro Kenshuusei Happyoukai 2014 ~Haru no Koukai Jitsuryoku Shindan Test~ event, Makoto announced that Kosuga had finished her training. Her profile on the up-fc website was removed on May 28.
