The Explanation of Lithic Reduction Technology of the Early Paleolithic : On the Japanese Archipelago in terms of Comparative Studies for Kamitakamori and Sodehara 3

直立人很可能是流动的，但在面对某些情况时，他们无法将原材料带到他们的营地/地点。为了减轻频繁移动带来的负担，他们在获得丰富、优质的原材料后，立即生产出工具和可用的薄片。他们在每年的轮换期间，通过随意制造额外的石器工具来翻新他们的装备。因此，他们经常把完成的工具、预制品或可用的不同原料薄片带到战略位置。就像使用山间小屋的现代猎人一样，他们为自己的营地提供了物资。他们会在预先确定的迁徙路线上的后勤点上储存成品工具，以应对恶劣的条件、石器资源的不均匀分布、频繁迁徙的压力以及搬运重物的必要性。因此，被丢弃的人工制品的地点可以被视为空间上的集中，可以被视为重新装备的后勤场所（Kamada 1995, Kajiwara et al . 1996）。

It is likely that the populations of Homo erectus were mobile but they werer unable to carry raw materials to their camps/sites when faced with certain sitations. In order to lessen the burden associated with frequent mobility, they manufactured the tools and usable flakes instantly after procuring abundant, good quality raw materials. They refurbished their gear by the casual manufacturing of additional stone tools during their annual rounds. As a condequence they often brought completed tools, preforms, or usable flakes of differentiated raw materials to strategic locations. Like modern hunters who use mountain huts, they provisioned their sites. They would stock logistical points on their predetermined migratory route with finished tools when copint with harsh conditions, the uneven distribution of lithic resources, the presures of frequent moves, and the necessity of carrying heavy burdens. Hence sites with discarded artifacts found as spatial, delineated concentration can be viewed as logistical locales for retooling (Kamada 1995, Kajiwara et al 1996).
