This chapter discusses the practice of ritual tooth ablation in Japan in relation to diet and migration. Ablation was practiced extensively among hunter-gatherers, and the tradition typically followed one of two patterns, type 4I and type 2C, depending on whether the lower incisors or canines were extracted, respectively. To test the hypothesis that a dependence on marine resources for food differed depending on ablation type during childhood and adulthood, stable isotope ratios of bone collagen and tooth enamel were measured. It was discovered that diets did vary among individuals with different ablation types in the Inariyama population. The findings provide important evidence that biocultural dietary differences were related to ablation type in the Jomon period.
