Yamamoto was born in Yokohama, Japan on October 3, 1943. He studied law at Keio University and graduated in 1966 with a law degree. He continued his studies on fashion design at the famous Bunkafukuso Gakuin, a fashion institute in Tokyo. Yamamoto blends the exotic and powerful designs of traditional Japanese dress with Western daywear, and achieves a unique, abstract style. He is an uncompromising, nontraditional designer. Yamamoto drapes and wraps the body in unstructured, loose, voluminous garments, similar in style and philosophy to those of Rei Kawakubo. Many of his clothes have additional flaps, pockets and straps.
