Though formally educated and licensed as a pharmacist, Masako Isojima - mother of Yuka, the founder of rikumo - found her true calling as an artist who explores diverse media, establishing a portfolio that includes painting, woodcarving, botanicals, and sashiko needlework. While in her 60s, friends in the art community encouraged her to take up pottery as well, a pursuit that culminated in her first solo exhibition, Tuchi Asobi, or "Play with Clay." Today, Isojima continues to work out of her Tokyo studio, creating handmade ceramics of a uniquely organic nature.
