This study examined temporal changes in the archaeological records of the Pleistocene/Holocene transition in Hokkaido, northern Japan, based on assemblage composition, radiocarbon ages, projectile point flaking pattern, and site distribution, with a particular focus on the lithic reduction technique. It explained the formation processes of Jomon society in response to climate change as follows. In Hokkaido, pottery emerged during the Late Glacial (LG) warm period (ca. 15,000–13,000 cal BP) because the Incipient Jomon people migrated from Honshu to the north. The Incipient Jomon communities coexisted with the Terminal Upper Paleolithic (TUP) people that had continued to occupy the region since the stage prior to the LG warm period, but the Incipient Jomon population was relatively small. During the LG cold period (ca. 13,000–11,500 cal BP), the subsistence and settlement strategies adopted by the Incipient Jomon people could not continue in Hokkaido. There is currently no reliable evidence of human activity during the LG cold period.

Nevertheless, the analysis of stone tool-making patterns has revealed that stone tool making originating among the TUP people is found in an early Initial Jomon assemblage from the Taisho 6 site. It has an accepted date range of 11,000–10,000 cal BP. This indicates that TUP people's more mobile lifestyle might have enabled them to adapt to the LG cold environment. In the initial Holocene, there was a change in subsistence strategy evidenced in the increase in pottery vessels and the emergence of tools for processing of plant foods. The dramatic warming at the beginning of the Holocene is thought to have significantly changed the TUP people's subsistence strategies and lifestyles.

本研究根据组合成分、放射性碳年龄、弹丸点剥落模式和场地分布，检查了日本北部北海道更新世/全新世过渡时期考古记录的时间变化，特别关注岩屑还原技术。对绳文社会应对气候变化的形成过程进行了说明。在北海道，陶器出现在晚冰期 (LG) 暖期（约 15,000–13,000 cal BP），因为初期绳纹人从本州迁移到北部。早期绳纹族群与自 LG 暖期之前阶段就继续占据该地区的晚期旧石器时代晚期 (TUP) 人共存，但早期绳纹族人口相对较少。在 LG 寒冷期（约 13,000–11,500 cal BP），初期绳纹人所采取的生存和定居策略无法在北海道继续下去。目前没有可靠的证据表明 LG 寒冷时期人类活动。

尽管如此，对石器制作模式的分析表明，起源于 TUP 人的石器制作是在大正 6 遗址的早期初始绳文组合中发现的。它的可接受日期范围为 11,000–10,000 cal BP。这表明，TUP 人更多的移动生活方式可能使他们能够适应 LG 寒冷的环境。在最初的全新世，陶器的增加和植物食品加工工具的出现证明了生存策略的变化。全新世初期的剧烈变暖被认为显着改变了 TUP 人的生存策略和生活方式。
