I WiSH was a Japanese pop group consisting of two members, Ai Kawashima and nao. Ai is responsible for the vocals and occasionally plays the piano also with nao on the keyboard or piano. Their most notable track is "Asu e no Tobira" and was in the Oricon rankings for over a year.
Nao learned the piano when he was 5 years old. He started making original music, for example "Asu e no Tobira", "Futatsuboshi", "Yakusoku no Hi" and so on. He won the grand prix held by YAMAHA. According to his website, he has a perfect pitch.
Ai Kawashima's father was missing before she was born, and her mother died when she was just three years old. She was adopted by Kawashima’s family as an adopted daughter after she spent some time in an orphanage. She learned how to play the piano when she was only 3 years old.
