The outdoor joint live “W-KEYAKI FES.2021”, a sister group of Sakurazaka46 and Hinatazaka46, was held on the 11th at Fuji-Q Highland Conifer Forest with spectators. The venue is a “sacred place” where both groups have held live performances of “Keyaki Republic” for three years from 2017. After the cancellation due to the corona disaster last year, this was the first joint live with the intention of the two groups to celebrate each other’s growth in the sacred place. A total of 46 people, including 25 Sakurazaka46 members and 21 Hinatazaka46 members, sang a total of 23 songs. At the opening, the members of both groups lined up as if they had spread their wings, and were greeted by a big applause from the audience with a stick balloon. Rina Inoue (20) of Sakurazaka46 was deeply moved by the realization of the live, saying, “It’s a reality that two groups will perform live together …”. “Let’s make everyone and we the best memories of this summer,” he said enthusiastically. The live performance consists of Sakurazaka46 on the 9th, Hinatazaka46 on the 10th, and joint on the 11th. Hikaru Morita (20) of Sakurazaka46, whose birthday is on the 10th, said, “I was 19 on the first day, but today I want to go to adult Morita.” Manamo Miyata (23) of Hinatazaka46 called out, “Buddy’s (Sakurazaka46 fans) and Ohisama (Hinatazaka46 fans), let’s enjoy together today!” It was exciting.
