縄文土器は、多くの型式編年研究、つまり土器の形や模様で時期の順番をつける研究によって、世界的にも類をみないほど精緻な相対順序が判明しています。一口に“縄文土器”といっても地域毎に30ほどの時期に区分された年表が作れるのです。炭素14年代測定での絶対年代も、型式編年での順番とほぼ合致します。日本の細かい土器編年はとても正確なのです。一方、関東と東北の関係など地域間の横の関係については年代値によって検討していくべき余地もあります。土器が出土する遺跡の変遷などを実時間スケールで調べます。

Jomon pottery has been the subject of numerous type-sequence studies — studies that assign chronological order to the shapes and patterns of earthenware, revealing a relative order that is unparalleled in its precision. We can create a chronology that divides the age of Jomon pottery into as many as 30 time periods for each region. The absolute age of Jomon pottery, as determined by radiocarbon dating, is almost identical to the order in type chronology. Therefore, the detailed chronology of Jomon pottery is accurate. Nevertheless, there is room to better examine the horizontal relationships between regions, such as the relationship between the Kanto and Tohoku regions, based on chronological values. In this way, we can investigate the transition of a site where the earthenware was excavated on a real-time scale.

炭素14年代測定などを用いて、縄文土器や縄文時代の集落を中心に研究しています。具体的には、縄文年代論、縄文文化の起源、縄文土器の製作技法や文様装飾、付着物の同位体分析やレプリカ圧痕法による食性（植物食中心だったのか、など）の解明、縄文中期の環状化集落の形成過程、弥生文化への移行などに興味があります。

This research focuses on Jomon pottery and Jomon-period settlements using carbon-14 dating and other techniques. Specifically, it investigates Jomon chronology, the origins of Jomon culture, and Jomon pottery production techniques and decorative designs and seeks to elucidate dietary habits (e.g., whether the people were mainly plant eaters) through isotope analysis of charred materials on potsherds and replica indentation methods, the formation process of encircling settlements in the middle Jomon period, and the transition to Yayoi culture.
