Japan Mystery

Why did Japanese women once paint their teeth black? What did real ninja actually wear? Why do castle floors chirp like birds? Japan Mystery turns the strangest true stories of Japanese history, folklore, and everyday custom into short visual mysteries. Each question takes seconds to answer — and leaves you with a story worth retelling. ONE MOONLIT NIGHT Every mystery is illustrated in a single, hand-crafted world: an ink-dark night, one gold moon, and the silhouettes of old Japan. No noise, no clutter — just you and the question.
