A photographic journey into Chieko Shiraishi's memory, exploring reflections, experiences and a fascination with the many small outer islands that surround Japan. Shimakage, literally island shadow, brings together images taken on islands and coastal areas such as Sakushima, Shingu and Kihoku in Mie. The images are gelatin silver prints that use an old retouching technique known as zokin-gake, or rag-wiping, popular among amateur photographers in Japan in the 1920s and 30s, so that they evoke a faded memory: the landscapes appear and disappear within the picture, faint signals and silhouettes against the backdrop of an obscured memory. In the afterword Shiraishi recalls a vague childhood memory of a trip to Penguin Island, of which the scenery seen on the way returns only dimly, like a scene in an unreal picture; the island that sends small signals from memory is a phantom island, and its shadow drifts at the bottom of a dim memory.
