Risako Sugaya (菅谷 梨沙子 Sugaya Risako, born 4 April 1994 in Kanagawa, Japan) is a former Japanese pop singer, and actress. She first gained recognition when she joined Hello! Project Kids and later became one of the lead vocalists of the girl group Berryz Kobo from 2004 to 2015.
2002-2004: Hello! Project Kids, 4Kids
In 2002, Sugaya auditioned for Hello! Project Kids with the song "Minimoni Hinamatsuri" by Minimoni. Her audition tape was aired on Morning Musume's variety show Hello! Morning. She was placed in the group with 14 other girls. She made her first appearance as an angel in the 2002 film Mini Moni ja Movie: Okashi na Daibōken!; she also was one of the featured artists in the movie's ending song as a member of 4Kids.
In 2003, Sugaya starred in the movie Hotaru no Hoshi (蛍の星), as Hikari, a fragile elementary school student who, with the help of her caring teacher, has a chance to be momentarily reunited with her deceased mother and overcome her emotional problems. She also starred in the drama, Shonan Kawarayane Monogatari. That year also marked her first appearance on Kōhaku Uta Gassen, as one of Aya Matsuura's backup dancers, during the 54th edition of the renowned NHK New Year program.
2004-2015: Berryz Kobo
In early 2004, Sugaya became part of the newly formed group Berryz Kobo. Since joining the group, she has also participated in the band's weekly radio show Berryz Kobo Kiritsu! Rei! Chakuseki!. She has also, like other Hello! Project members, appeared in the Musume Dokyu! segments, namely episodes 39, 40, 54, 55, and 56. Additionally, Sugaya has done a commercial for the Nihon Shokuniku Shōhi Sōgō Center in October 2003.
On October 12, 2006, Sugaya became the first member of Berryz Kobo, and the youngest of all the Hello! Project members, to release a solo photobook. Even prior to its release, the photobook was met with mixed feelings both by Japanese and overseas fans. Sugaya herself admitted, in an interview with Sanspo.com, to initially having doubts regarding the photoshoot, but claims to have had a pleasant experience and hopes her fans enjoy the various facets of her personality.
On December 31, 2006, Sugaya once again took the stage at the 57th NHK Kōhaku Uta Gassen as a backup dancer in Morning Musume's performance of Aruiteru, along with the remaining members of Berryz Kobo, Country Musume and Cute. In mid-2009, Sugaya became a member of new unit Guardians 4.
On August 2, 2014, it was announced that Berryz Kobo would be going on an indefinite hiatus from the 3rd of March, 2015. Further, Sugaya announced she would be taking a break from show business following the cessation of group activities.
In October 2017, Sugaya announced her marriage to a man whose identity is undisclosed, and they met through a mutual friend. In addition to this, she was five months pregnant at that time. She gave birth to a girl at 1st of March 2018 and actively posting her and her daughter's life in her personal SNS
