A poetic memoir detailing Shigeru Mizuki's interest in yokai (spirit monsters). Mizuki’s childhood experiences with yokai influenced the course of his life and oeuvre. Within the pages of NonNonBa, Mizuki explores the legacy left him by his childhood explorations of the spirit world, explorations encouraged by his grandmother, a grumpy old woman named NonNonBa. NonNonBa is a touching work about childhood and growing up, as well as a fascinating portrayal of Japan in a moment of transition. Much like its namesake, NonNonBa is at once funny and nostalgic, firmly grounded in a sociohistorical context and floating in the world of the supernatural.
