Yonezawa Jiro gained his bamboo-crafting skills from senior bamboo artists in his home prefecture of Oita. During his thirties and forties he established a career as a bamboo artist in the US city of Portland, Oregon, before moving back to Oita in 2000. Yonezawa currently works in a studio surrounded by bamboo forests and abundant nature, and his works appear organic in shape and derived from nature rather than man-made.
