Like the samurai in many of his paintings on fabric, Hisashi Otsuka is an artist of remarkable dedication. Schooled in Zen and the martial arts, he has lived and worked by the warrior's code of discipline and duty. Rooted in Japanese tradition yet adventurous in nature, he is known throughout the world for his boldness of color and style that mark him as truly unique. See "Hisashi Otsuka". hisashiotsuka.com.
