Early Life[]

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.


In 2011, Kosuga auditioned for S/mileage Shin Member Boshuu! and successfully passed. She was introduced as a S/mileage sub-member at the Hello! Project 2011 SUMMER concert on August 14 along with Nakanishi Kana, Takeuchi Akari, Katsuta Rina and Tamura Meimi.[1]

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.[2]


In January, Kosuga returned to Hello! Project by joining Hello Pro Kenshuusei.[3] Her return was not revealed until March 13, when a picture of ℃-ute's Okai Chisato with the rest of Hello Pro Kenshuusei, including Kosuga herself, was posted on the Hello Pro Kenshuusei choreographer's blog.[4]

On March 16, her profile was added to the website for the upcoming March show alongside Uemura Akari, confirming she had officially joined the program.[5] Later on March 31, Fuyuka made her official return to Hello! Project by performing at the Hello Pro Kenshuusei Happyoukai 2012 ~3gatsu no Nama Tamago Show!~.

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

In November, Kosuga went on a hiatus along with Okamura Rise. She missed two Hello Pro Kenshuusei concerts as a result.


On March 31, when the news about the Hello Pro Kenshuusei Happyoukai 2013 ~Haru no Koukai Jitsuryoku Shindan Test~ in May was released, it contained Kosuga's name as one of participating members, confirming her return.[6]


On January 30, Hello Pro Kenshuusei appeared in Gekkan Entame magazine, and it was briefly reported that Kosuga was in poor physical condition.[7]

On May 4, at the Hello Pro Kenshuusei Happyoukai 2014 ~Haru no Koukai Jitsuryoku Shindan Test~ event, the MC Makoto announced that Kosuga had finished her training.[8] Her profile on the UP-FC website was removed on May 28.

On July 5, fans reported they had seen Kosuga with Mogi Minami at Otsuka Aina's solo event, Otsuka Aina Otsuka de Utau♪.[9][10]


On May 14, Kosuga signed to JAPAN MUSIC ENTERTAINMENT,[11] however by September her profile was removed, indicating she was no longer under contract with the agency.


In June, the website MISS COLLE began the Miss Jissen Contest 2017 for Jissen Women's University, where Kosuga was a student, and she had entered as the fifth contestant.[12] She opened a blog on MISS COLLE and accounts on Twitter and Instagram for her campaign. The voting period began on June 28 and ended on November 10. On November 11, Kosuga was announced as the winner.[13]

On December 28, Kosuga announced she entered the qualification round for the Miss of Miss Campus Queen Contest 2018 as the twelfth contestant out of 75 girls nationwide.[14][15] Public voting for the qualification round began that day and would end on February 28, 2018.


On March 2, it was announced that Kosuga had passed the Miss of Miss Campus Queen Contest 2018 qualification round to become one of 20 finalists.[16] Voting for final round was open from March 4 to March 25. The results were revealed on March 30, but she unfortunately did not win any awards.[17]

Personal Life[]

In 2011, Kosuga was diagnosed with severe anemia. As of 2012, she has recovered from the illness.

When Kosuga first joined Hello! Project, she was a second year middle school student. She attended and graduated from Hinode High School in March 2015, a school known for having students who are part of the entertainment industry.

As of April 2017, Kosuga is in her second year at Jissen Women's University, majoring in Humanities and Social Sciences. She is also a member of the Cultural Festival Committee.[18]

    • She was the only S/mileage sub-member to have never become a full 2nd generation member.
    • She was the first Hello! Project member to be downgraded to an Hello Pro Kenshuusei member.
    • During her time in S/mileage, she was able to make a short appearance in the music video and a live performance of "Busu ni Naranai Tetsugaku" and was featured in S/mileage's 2012 calendar; all which were release after her departure.

    • In late 2013, Tsunku commented on Kosuga: "Your dancing has gotten good. I think you've grown to a great extent. In the beginning you were the type to not be able to do anything so I was worried, but now you've probably come to a position in the top half of the group. However, you can aim even higher. Get your rhythm under control!"[20]
