Rieko is best known for her detailed portraits of anthropomorphic creatures, usually animals or well-loved toys. A self-taught artist and illustrator, she was born in Japan and has lived in Wellington for 19 years. Her first exhibition was held in 2010, followed by several solo shows and group exhibitions in Wellington and Auckland. Every one of her solo shows has sold out. Her most recent exhibition "Aotearoa" was well received during Art Week 2018.
Rieko is represented by Warwick Henderson Gallery in Auckland and her limited-edition giclée prints are available from Eyeball Kicks Gallery in Wellington.
