 The dogū was unearthed in a field overlooking the Pacific Ocean on the east coast of the Oshima Peninsula in August 1975, by a housewife turning over the soil with a hoe to harvest potatoes.To provide contextual information, a trench was opened and a Late Jōmon pit burial identified, complete with a jade pendant and fragments of a lacquered hairpin.In 2006, more detailed investigations were carried out over a wider area, uncovering further grave pits, refuse pits, lithics, and ceramics, as a well as a stone circle.
