Koyo Saruhashi no zu (The Monkey Bridge in Kai Province)

The "Monkey Bridge" is one of the rarest of Hiroshige's masterpieces and is considered to be the finest in the vertical-diptych format. The design is thought to have been completed soon after his journey in 1841 along the Koshukaido, the road from Edo (Tokyo) to Koshu (Kai province) near Lake Suwa on the Kisokaido. Another impression of this image is in the Tokyo National Museum and is a registered Important Art Object.
