Okada Koichi is known for his series of woodblock prints “Twelve views of Japan”, created around the year 1950. The series might have been intended to consist of twelve different prints, but only six are known. They depict the mount Fuji seen from Hakone, Lake Kawaguchi, Lake Ashinoko, Hagoromo and overlooking Nihondaira. All these have been printed using the original woodblocks by Unsodo, the same publisher that published the first editions.
