Singer-songwriter Kawani Shinatsuki will release his new single “optimism” on Friday, July 11th.
Since “The Ideal Girl” was released last year, Kawani Shinatsuki has been attracting attention mainly on social media for her highly sympathetic lyrics and catchy melody, and has captivated many listeners not only in Japan but also in Asia, including Korea. In November last year, he performed at his first overseas event in Korea, and in May this year he also appeared at a music festival in Taiwan, greatly enthralling local audiences.
This work, “optimism,” is a song featuring Yamamoto Show, who has provided songs across artist genres, including writing and composing the lyrics for FRUITS ZIPPER’s “My Cutest Things.” With its pop sound, it is a life-size, positive song that teaches us today the importance of living around “fun” rather than “correctness.”

■Comments from Kawani Shinatsu
Tokyo is full of people coming and going, information, and “cute.”
In the midst of this whirlwind, as I searched for what “personality” means, I may have forgotten to enjoy it at some point.
This work, “optimism,” describes the importance of living on “fun” rather than “correctness.”
To become an adult means to become someone. Instead, try to believe in an invisible future with a little optimism.
Perhaps it’s about having that kind of “softness”. He gently tells me. I would be happy if it became such a song.
This is also a special song that was born for Kawani Shinatsuki for the first time by entrusting the lyrics and composition to others.
May my voice gently and deeply reach your heart, along with the many thoughts that reside in this song.
