As evidenced by findings from the Iwajuku site to results of excavations around the country, a paleolithic culture did exist in the Japanese archipelago. However, there are almost no surviving artifacts of what could be termed plastic art.

A team of about 50 researchers reviewed scientific literature from 1953 to the present and made a database of marine species living in Japan's exclusive economic zone (EEZ).

The seabed in that area is 130 million years old, but the volcanic rocks there have been estimated to be around only 50,000 to one million years old.

The results showed that although the area has only 0.9 percent of the total volume of sea water, it is home to 33,629 marine species.

Fujita Masaki, a member of the research team, said, "We had assumed Paleolithic peoples mainly hunted deer and wild boar. But these hooks give us a totally different image of what life was like then."
