Jomon ware is one of world's the earliest pottery created in Japan from about 14,000 BC to 300 BC. Typical Jomon pot is decorated with hand-engraved rope patterns as shown in Figure 1(a)(b) [Habu 2004]. The rope patterns are synthesized by rolling a rope on the surface of a pot before baking it. Different styles of ropes make great different rolling patterns, and each Jomon pot has characteristics that can be traced to their age and area of origin. Many archaeologists are doing research on the relationship between rope styles and the patterns [Takaki et al. 2011].
