Chiba, Japan (2000 – present) Ceui (born January 31) is a female Japanese singer–songwriter originally from Chiba, Japan, though she grew up in Fukuoka. Ceui's name is derived from the Portuguese word for sky, céu. Due to the influence of her mother as a piano teacher, Ceui began learning classical piano from the age of six. As a young girl, she became interested in children's literature and poetry, and began writing verses herself. As a student, she was a member of the wind instrument club and choir.
