The small excavation of the Shimmeiyama Site, a prehistoric one in Musashi, yielded 376 potsherds and 4 stone artefacts. Potsherds were of the Early Jomon type, and three patterns of design were identified among them except for those with no decoration ; twisted cord patterns, cord patterns proper and incised patterns. Stone implements are all polished. Chronological situation of the site is not yet determined.
