Arai Tasuku is a Japanese composer. Since his childhood, he learned how to escape into a dream. Always wanted to meet in reality to whom met in a dream. Living from day to day in modern society with the struggle of knowing that it is an unrealizable dream. Composing music with the sound brought back from a pillow is his niche, and the stories gathered with threads with his hand are just like in a dream covered with patches. He is known as an artist, and also works on visuals, sound design, space director, and engineer etc.
