The pottery discovered at the Komakino Site that dates back to the Late Jomon Period consists of bowls, vases, and serving jugs. Not only is there a noteworthy increase in the amount of pottery being produced, but the techniques utilized in the production of the pottery are also much more advanced than those used in earlier periods. Additionally, pottery was also made with a clear purpose in mind, whether it be for everyday use or for use in rituals.
