“…There is considerable evidence for trade and exchange within Japan during this period but, with some exceptions, the possibility of trading contacts with the mainland has rarely been discussed (Bausch, 2016). The specialist craft production found in the Late-Final Jōmon included ceramics, shell beads, jadeite ornaments, greenstone beads, polished stone axes, lacquerware and salt (Kinoshita, 2003;Bausch, 2004Bausch, , 2010Sakaguchi, 2011;Kawashima, 2015b;Matsumoto, 2011Matsumoto, , 2018a. The existence of very long-distance networks at this time is clear and Final Jōmon Kamegaoka pottery from the Tohoku region is found as far south as Okinawa (Shitara, 2018), some 2000 km as the crow flies, equivalent to the distance from Paris to Athens.…”
