Karhu has lived in Kyoto, Japan for over fifty years. He was born in Minnesota. Karhu's woodblock prints are closely related to the woodblock prints of the past. However, Karhu not only designs his prints but has mastered the meticulous cutting and printing process which the Ukiyo-E Masters left to their assistants.
Karju has a talent for creating mood by using soft touches such as illumination falling onto a street at dusk. He is considered by many to be the most important landscape woodblock print artists in Japan even though he is an American.
