Kaori was born in Japan but spent most of her childhood in Singapore. After returning to Japan, she went on to study at the Tama Art University in Tokyo graduating in 1993. An apprenticeship followed in theatre and costume design working with a renowned costume designer. In 1997 she spent four years working as a curator, travelling extensively around Japan, discovering and mentoring new artists and organising exhibitions for them.
During this period, her parents lived in Asia, America and Europe. In 2001, while her parents were living in London, Kaori visited the UK. During this trip she enrolled on a bookbinding course with Midori Kunikara-Cockram at Jade Studio and later with Mark Cockram at Studio 5. Following this and deciding to stay in the UK, she took a place at Camberwell University of Art where she studied print making and graduated with a MA in 2005. Returning to bookbinding full time in 2006, Kaori is now working at the Wyvern Bindery in London and she undertakes private commissions. In 2008 she was elected as a Licentiate of Designer Bookbinders. Her work has won many prizes and she has books in private collections in the USA and the UK.
