Yukio Shiihashi (born 1939) is a Japanese local historian and documentary photographer specializing in folk religion and rural cultural heritage. Since the mid-1980s, he has conducted extensive fieldwork on *sōtai dōsojin* (paired roadside deities) and later expanded his research to silkworm deities and Japan's sericulture traditions. Through decades of nationwide surveys and photography, he has documented religious statues, stone monuments, hanging scrolls, and other folk artifacts that are rapidly disappearing. His book *Kaiko no Kamigami* (*The Gods of the Silkworm*) is an important visual record of Japan's sericultural beliefs and regional folk traditions.
