Jurina Matsui(松井 珠理奈,Matsui Jurina?, born March 8, 1997 in Aichi Prefecture) is a member of Japanese idolgirl groupsSKE48 and AKB48. In SKE48, she is a member of Team S, and in AKB48, she is a member of Team K. At age 11, she became the first member from an AKB48 sister group to perform on AKB48's main single and also perform as its center position.
In sixth grade, Matsui auditioned with SKE48 in July 2008 and was selected with 22 other participants. The group debuted on October 5. In the same year, at age 11, she took part in the recording of AKB48's single "Ōgoe Diamond" and was selected as the center performer and cover girl for the single. It was the first time an AKB48 single would feature a member of a sister group. She has since participated in numerous singles for both groups. In early 2012, following scandals where they were photographed with their boyfriends, Natsumi Hirajima and Rumi Yonezawa resigned from AKB48. Matsui then joined AKB48 as a concurrent member.
On March 25, at AKB48's concert at Saitama Super Arena, Matsui suddenly left in the middle of a song. She was diagnosed with "dizziness due to anemia, overwork" and was hospitalized for a few days. According to the event manager, in the past few months there had been reports of her poor physical condition, but she had stated that she "absolutely did not want a break". AKB48's producer Yasushi Akimoto informed the group's fans that he had let her rest for an indefinite period of time.
At the 2012 AKB48 general election to determine the lineup of its 27th single, Matsui placed ninth overall with 45,747 votes, the highest for an SKE48 member. For the next single, "Uza", Matsui was selected to be the center performer along with top vote getter Yuko Oshima. She was selected ahead of Mayu Watanabe, even though the latter had garnered more votes from the election. In the rock-paper-scissors tournament for the 29th single, she lost in the second round to Mariko Namamura.
In the 2013 general election, she placed sixth overall with 77,170 votes. In September 18, she won the rock-paper-scissors tournament to become the center performer for the group's 34th single.
In the AKB48's 37th Single general election, she placed fourth overall with 90910 votes.
