Miyamoto Karin (ex.Juice=Juice) has launched an official Twitter account (@karin__miyamoto). 

Miyamoto graduated from both Juice=Juice and Hello! Project on December 10 after the group's one-man live 'Juice=Juice Concert 2020 ~Tsuzuiteiku STORY~ Miyamoto Karin Graduation Special.' Afterwards, she opened a YouTube account and uploaded the music video of her solo song "Mirai no Filament" which she performed during this concert. In her first tweet, she wishes BEYOOOOONDS member Hirai Miyo, who turned 21 on December 11, a "Happy Birthday."
