Koichi Okumura was one of many artists who designed woodblock prints for the publisher Unsodo. Okumura's woodblock prints were included in the 1948 series, Twelve Views of Kyoto, along with several other artists. That same year, he also designed a group of smaller chuban prints titled Eight Views of Kyoto. During the early 1950s, he designed several other landscape prints, including prints of Mt. Fuji and the Inland Sea.
