Momoko Okada was born and raised on a dairy farm in Hokkaido, Japan. Momoko began studying metals and glasswork in the U.S. and the U.K. and received B.F.A. from Southern Illinois University. Then she started to realize that the importance of her Japanese heritage and began studying traditional Japanese metals techniques at Kanazawa College of Art. After receiving M.F.A. in Japan, she continued her graduate study on differences of Eastern and Western aesthetics and metals techniques at Bowling Green State University. She has been practicing the traditional Japanese metalsmith work for over 15 years. One of the traditional metals techniques that she uses is called "Zogan" and it means inlay. Metal inlay technique is a process to imbed wire or sheet metal into a different metal without heat.

In 2015, Momoko and her master teacher, Kazuo Kashima (5th generation master of Nunome Zogan technique) decided to spread the technique beyond Japan to keep these beautiful tradition from disappearing. Momoko started to offer classes and workshops on those traditional metal inlay techniques at Portland parks and recreation, various schools and privately to spread the knowledge to the Western artists. In 2016, since the inlay tools and materials are hard to obtain in the U.S., she created an online store, Momokoya.com, to help students to maintain their skills and to achieve their goals. She relocated her studio to Tucson AZ in 2018 and start teaching at Tucson Parks & Rec. and Pima Community College.

In 2024, Momoko moved back to Japan to save her parents dairy farm and ice-cream business. Momokoya.com has been sold to her student, however, she still helps out as consultant and keeping the business going. This will be her first online workshop from Japan!
