The town of Kumakogen in northern Ehime Prefecture has suffered a decline in population, with its demographic becoming increasingly graying. To prompt villagers into thinking more about their community and how to revive it, a local museum asked photographer Keiko Sasaoka to document the town, and it's beautiful surrounding areas, for a public exhibition.

One of the major projects Sasaoka worked on was a photographic version of the 26 views depicted in the "Kumayama Shinkei Emaki," an Edo Period (1603-1867) picture scroll by Hirozane Endo. A hundred and fifty years on, Sasaoka revisited the same areas and took photographs to illustrate how much Kumakogen has changed; till May 20.
