Minatogawa Man

The Minatogawa people are a prehistoric people of Okinawa, Japan, represented by four skeletons, two male and two female, and some isolated bones dated between 16,000 and 14,000 years BCE. They are among the oldest skeletons of hominids yet discovered in Japan.

The skeletons were found at the Minatogawa limestone quarry, located 10 km south of Naha, near the southern tip of the island. Okinawan businessman and amateur archaeologist Seiho Oyama noticed fossil bone fragments in some building stone blocks he had purchased from the quarry, and for two years he kept watch as the quarry was worked. In 1968 Oyama reported the finding of a human bone at the quarry to Hisashi Suzuki, a professor at Tokyo University.

A team led by Suzuki excavated the site during three seasons (1968, 1970 and 1974). Their finds were described in 1982. The skeletons are now in the Anthropology Museum, Tokyo University.

All skeletons were found buried inside a vertical fissure in the limestone rock, about 1 meter wide, which had been filled over millennia by residual red clay mixed with travertine, limestone fragments and bones. Suzuki's excavation was limited to the part of the fissure that was exposed on the quarry's face, 5 m high and 20 m above the present sea level, and extended about 6 m into the cliff behind.

The bones recovered from that fissure belonged to between 5 and 9 distinct individuals (two males and the rest females), mixed with over 200 fragments of deer and boar bones. The finds lay on a diagonal band extending down and forward by about 6 meters within the fissure. The lowest-placed skeleton (Minatogawa I, a male about 25 years old) was standing upside-down, but his bones were mostly in their anatomical positions. The other skeletons were found with their bones all mixed up and scattered over several meters. Skeleton IV, in particular, was found as two sets of bones separated by a couple of meters; his skull has a perforation that seems to have been caused by a sharp hard point, and his left and right arms seem to have been fractured the same way. Suzuki conjectures that the individuals were killed with spears or arrows by enemies who cannibalized their victims (breaking bones in the process) and then threw the remains into the fissure, which had been used as a trash dump (which explains the animal bones).
