The Japanese Upper Paleolithic, which lasted for 20, 000 years, from 33ka to 13ka (uncalibrated 14C dates), is divided into the early and latter halves, the boundary of which corresponds roughly with the timing of the AT tephra fall (ca. 25ka). This paper subdivides the early half into two phases and the latter half into three phases, and overviews lithic industries phase by phase, with special regard to human adaptation to a cold climate. The first phase of the early Upper Paleolithic is represented by edge-polished axes and truncated knives, and the second phase by the establishment of blade technology and the emergence of backed knives. The first phase of the late Upper Paleolithic is characterized by the emergence of localism, and the middle phase by the local development of spear point industries. The third phase of late Upper Paleolithic is recognized by the development of microblade industries over the entire Japanese Island.The end-scraper that emerged in the first phase of early Upper Paleolithic was not a ubiquitous tool-type throughout the Upper Paleolithic, and it shows an uneven distribution both temporally and regionally. It occurs more frequently in the higher latitude areas. Used-wear analysis suggests that the end-scraper is an implement for hide processing. Fur is an important garb use for protection against cold weather. Therefore, the end-scraper can be regarded as an indicator of human adaptation to a cold climate. Many recent studies focus on the precise chronology of the Upper Paleolithic in each area and its correlation to environmental events reconstructed by the oxygen isotope stage and other environmental data. The study of the end-scraper is a fruitful approach which enables us to understand a human strategy for adapting to the coldest climate in the Last Glacial Maximum.
