Transoceanic similarities
Jōmon society is often compared to pre-Columbian cultures of the North American Pacific Northwest and especially to the Valdivia culture in Ecuador, including ceramics, because in these settings cultural complexity developed within a primarily hunting-gathering context with limited use of horticulture. Whether these similarities developed independently or were the result of Jōmon seafarers getting lost is debated issue.
