He won a Canon New Cosmos Prize in 2004, winning praise from Nobuyoshi Araki. In 2008, he published “Sou,” an unflinching, often difficult look at a number of events in his family life: the death of his wife’s parents and their cat, followed by the birth of his own child. Two years on from that project, Takiguchi is in the middle of a new series, “PEEP.” This work should earn him a new level of appreciation within Japan, and hopefully outside of it as well. “Sou” is remarkable for its direct approach to Takiguchi’s own pain and joy, but with “PEEP” he has distinguished himself from many of his contemporaries by making a similarly direct inquiry into questions of class, happiness, family, work and vice in current Japanese culture.
