It is said that the Jyoumon Age Culture continued from 16, 000 years ago to 2, 500 years ago and the people who bore the culture is called Joumon-jin. Earthen ware that were produced by Jyoumon-jin are called Joumon-doki. Jyoumon-doki have been discovered in various parts of Japan and there are many kinds of them. Among them, one discovered at Umataka-ruins in Niigata Prefecture at the end of 1931 is very famous for its nice patterns and it was named Kaen-doki.The patterns on its lip and side wall are related to the water flow, the authors believe. The nice vortex patters of Kaen-doki put on their side wall are two kinds of vortex observed down stream of piles and rocks in the river acting the pollen and fallen leaves, etc. as tracers.This fact was appeared again using Floating Tracer Method, one of the visualization methods of modern age, and the computer simulation.
