  Archaeologists have long used obsidian hydration dating method to give chronometric dates for obsidian artifacts. Models using these equations independently employ different measurement systems, which are based on rim thicknesses determined by optical microscope and hydrogen depths measured by secondary ion mass spectrometry (SIMS), respectively, although the inconsistency of both measurements has been reported. Firstly, this paper describes a systematic comparison that was done on optical rim thicknesses and hydrogen depths by means of an isotope microscope, which provides micro-imaging with SIMS. Depth profiles of hydrogen were precisely obtained from the spots where optical measurements were taken on the archaeological obsidian flakes from two distinctive cultural horizons (older: Upper Paleolithic, younger: Initial Jomon) in the stratified open-air site of Jozuka in southern Kyushu (Japan). Secondarily, using the measurements of hydrogen depths that are the most consistent to the measurements of optical thicknesses, the estimated hydration rate of the Holocene (Initial Jomon) is slower than that of the Late Pleistocene (Upper Paleolithic), implying that the difference in hydration rates was due to the difference of intrinsic water content of obsidian and/or obsidian geochemistry. An application of micro-imaging with SIMS to measure hydrogen depths on obsidian shows promise as a tool for improving the practice of hydration dating and evaluating local climatic condition.

• On the Pleistocene Population History in the Japanese Archipelago

  CURRENT ANTHROPOLOGY 58 S539 - S552 0011-3204 2017/12 [Refereed][Invited]
   

  This paper provides a current understanding of human population history in the Pleistocene Japanese Archipelago, particularly with respect to the routes and timing of hunter-gatherer migrations, by incorporating multiple lines of evidence from the records of archaeology, human paleontology, and genetic studies. The human fossil remains are concentrated on the Ryukyu Islands in southwestern Japan, suggesting that there may have been a northward migration via the Ryukyu Islands. In contrast, studies of ancient mitochondrial DNA demonstrate genetic continuity among Holocene hunter-gatherer populations in the Paleo-Sakhalin-Hokkaido-Kurile Peninsula, whereas the Pleistocene genetic history is little explored. Although it is largely supported, the assumed population continuity from the Pleistocene to the Holocene inside the Japanese Archipelago is also challenged by an examination of the Paleolithic record and a comparison of the short-and long-term chronologies of the Japanese Paleolithic, implying that the Japanese Paleolithic record was created by hunter-gatherer population migrations from the north and south with substantial time lag and endemic technological invention and transformation during the Late Pleistocene.

  The wedge-shaped microblade core technology found along the northern Pacific Rim has been regarded as a trait of hunter-gatherer adaptation during the Late Glacial and initial Holocene. Having recognized variable microblade core reduction methods among the technocomplexes in Hokkaido, by employing an optimization model in lithic technology, the present paper addresses the question of what role bifacial microblade core technologies played in foraging, through a comparative analysis of utility, cost of transportation, and failure rates between the larger ("Sakkotsu") and smaller ("Oshorokko") bifacial microblade core technologies in the Late Glacial Hokkaido. Results suggest that as opposed to the larger bifacial microblade core technology, the smaller bifacial microblade core technology was more effective for exploring unpredictable environment across the northern Pacific Rim.

• The significance of obsidian hydration dating in assessing the integrity of Holocene midden, Hokkaido, northern Japan

  Since its novel invention in 1960, obsidian hydration dating is now recognized as the chronometric method to give dates of archaeological sites, based on measurements of hydration rim thickness. Contrary to the increased awareness of various factors that affect hydration rates and reliability in measurements, the question whether and the extent to which the validity in the rim thickness measurements corresponds to the interested event has been less discussed. Here, validity of obsidian hydration dates that designate event of human site occupations is discussed in terms of site integrity of the Early Jomon midden in the Holocene site of Ocharasenai (OCH), Hokkaido, northern Japan. Expected integrity of the midden evidently left by prehistoric hunter-gatherers is tested through a comparison of microscopically-measured average rim thicknesses between the primarily extracted specimens and those chosen after assessing the validity. No statistical difference in estimated hydration dates between these two groups supports high integrity of the midden. The estimated date for the Early Jomon occupation at the OCH is 4388-4942 BP, fallen into the end of Middle Holocene. Results of the present examination indicate that obsidian hydration dating will aid to understand site formation processes. (C) 2015 Elsevier Ltd and INQUA. All rights reserved.

  GEOARCHAEOLOGY-AN INTERNATIONAL JOURNAL 29 (3) 202 - 220 0883-6353 2014/06 [Refereed][Not invited]
   

  As debates about the late Pleistocene human occupation of northeast Asia continue, the Last Glacial Maximum (LGM) prehistory of Hokkaido becomes more relevant. A geoarchaeological evaluation of key sites on the island will provide important evidence to understand human adaptive responses to LGM environments. Kawanishi-C is located on the middle terrace of the Satsunai River, eastern Hokkaido. Previous salvage excavations totaling 5756 m(2) revealed three archaeological layers in eolian sediments: (1) an early Jomon component above the Ta-d tephra (similar to 7000 cal. yr B.P.), (2) a microblade component between the Ta-d and En-a tephras (similar to 15,000 cal. yr B.P.), and (3) a blade/flake-based assemblage between the En-a and Spfa-1 tephras (27,000-25,000 cal. yr B.P.). Integration of geoarchaeological investigations and statistical analysis of the artifacts' spatial distribution indicates that the relatively low energy eolian matrix preserved the site's behavioral context, though some post-depositional agent, such as frost heaving, may have slightly displaced the artifacts vertically.

  The effect of the Younger Dryas cold reversal on the survival of Late Glacial hunter-gatherers in the Japanese Archipelago is evaluated, through a synthetic compilation of (14)C dates obtained from excavated Late Glacial and initial Holocene sites (332 (14)C dates from 88 sites). The estimated East Asian monsoon intensity and vegetation history based on the loess accumulations in varved sediments and pollen records in and around the Japanese Archipelago suggest an abrupt change to cool and dry climate at the onset of Younger Dryas, coupled with the Dansgaard-Oeschger Cycles as recorded in Greenland. The chronometric placement of sites based on an assessment of (14)C dates show that the site numbers decrease from the Bolling-Allerod to Younger Dryas and increase from the Younger Dryas to Preboreal. However, human population dynamics inferred from a site distribution analysis was little changed from the previous Bolling-Allerod and to the following Preboreal. Moreover, hunter-gatherers consistently employed ceramic pottery technology since its emergence prior to the onset of Younger Dryas, while the quantity of ceramic vessels that were undermined during the Younger Dryas dramatically increased at the onset of the Holocene, implying that a substantial change in hunter-gatherer socioeconomy occurred after the end of Younger Dryas.

  An expansion in archaeological excavations and site identifications over the last 30 years, particularly through an increase in salvage projects and the growth of government archaeology in Japan, has made the Japanese Islands one of the most dense regions of Palaeolithic archaeological sites in East Asia. The history of Pleistocene site discoveries and chronological frameworks for Palaeolithic lithic industries are summarized, followed by a critical review of research trajectories in the accumulation of a Palaeolithic record, specifically in terms of changes in relationships among academic archaeology, government archaeology, the public, and mass media. This article also attempts to clarify the peculiar structure of current Japanese archaeology that allowed the construction of a falsified Palaeolithic prehistory by some unscrupulous researchers for 20 years until its sensational exposure by a national daily in 2000. © 2011 by the University of Hawai'i Press.

  In order to better understand modern human behavioral variability in Hokkaido, Japan, we consider the geoarchaeology of the Kamihoronai-Moi site in terms of its geochronology, stratigraphy, depositional environments, and post-depositional disturbances. A Paleolithic component is stratigraphically situated between the Eniwa-a (15,000-17,000 C-14 yr B.P.) and the Tarumae-d (8000-9000 C-14 yr B.P.) tephras. Moreover, six AMS C-14 ages on charcoal from a Pleistocene-aged hearth feature are between 14,400 and 14,800 C-14 yr B.P. Quantitative examinations of patterns in artifact distributions show a low degree of vertical and horizontal displacement of chipped-stone artifacts, suggesting that, post-depositional movement of the cultural material was insufficient, to disrupt. the original pattern of artifact distribution.

  JOURNAL OF ARCHAEOLOGICAL SCIENCE 36 (3) 684 - 693 0305-4403 2009/03 [Refereed][Not invited]
   

  Stone boiling is one of the principal cooking methods used by hunter-gatherer societies. The present paper Proposes behavioral and organizational inferences as to how stone boiling was incorporated into hunter-gatherer subsistence practices through an examination of a sliallow-basin hearth in ail Early Magdalenian level (c. 15,500 (14)C B.P.) of El Miron Cave, Cantabria (northern Spain). Exploratory analysis of spatial patterns of archaeological remains (bones, lithic artifacts, and fire-cracked rocks) and use-life analysis of fire-cracked rocks demonstrate that the hearth was used and maintained during Visits Of humans who preyed mainly on ibex and red deer near the site. The relative accessibility of these ungulates and cost-induced technology of stone boiling suggest the implication that stone boiling was employed to maximize the energy and nutrition obtained from carcasses of these game taxa under the circumstance of resource intensification.

  Five decades of research history on the late Upper Paleolithic in Hokkaido (northern Japan) shows that microblade assemblages appeared by approximately 20,000 B.P. and that various microblade technologies were developed during late Pleistocene. The empirically observed good association between the morphological features of lithic raw materials and the reduction sequences of microblade cores demonstrates that morphological features of procured lithic raw materials (i.e., size and surface condition), which were constrained by unique geological and geoarchaeological characteristics in Hokkaido, created remarkable variability in reduction methods of microblade technology. This implies that geoarchaeological perspective can contribute to understanding technological variability in microblade assemblages in northeastern Asia. © 2005 by the University of Hawai'i Press.

  In order to detect the effects of thermally altered obsidian on lithic assemblage, prominent morphological characteristics of obsidian artifacts, which include crazing and breakages, were classified in examining a Meboshigawa 2 assemblage at a late upper Paleolithic site in Hokkaido, northern Japan.Observations made using a light microscope discerned six prominent morphological characteristics: crazing like a fingerprint, squamous crazing, tiny cracks, vesiculation, breakage with flat surface, and breakage with irregular surface. All specimens could fall into one of 33 categories in terms o...

  We clarified the internal structure of obsidian lavas from the following three localities; Shirataki in the north Hokkaido, Kozushima, one of the Izu islands, and the Kamchatka Peninsula in Russia. Based on the layer structure in obsidian lava and the rock texture and composition, we presented a formation model of obsidian caused by the promotion of outgassing and of rhyolite by leaving air bubbles through the cooling process of highly viscous magma. We constructed a systematic archeological obsidian research in Hokkaido. We made it possible to identify the sources of obsidian artifacts by the most practical and accurate method of combining X-ray fluorescence and neutron activation analysis. Analyses of more than 3,400 obsidian artifacts of the late Paleolithic sites in Hokkaido suggest that the behavior pattern of the hunter-gatherer group and accompanying obsidian procurement behavior changes with time as a boundary at the late glacial maximum of about 20,000 years ago.

  This study addressed the question as to the extent to which obsidian hydration dating has validity under the different climatic regimes recorded at the scales of regions and archaeological sites. I performed observations and measurements of obsidian hydration rims on archaeological specimens from the prehistoric sites located in various climatic zones including temperate and subarctic, as well as temperate zone in the Atlantic Ocean. The principal method of observation was thin-section method using the petrographic microscope, while selected hydration rims in a portion of samples were also observed using the secondary ion mass spectrometry that allowed one to measure the depths of hydrogen irons. The major results of this study are that estimated hydration rates not only vary depending on the climatic zones but also change in response to variations in endemic conditions notably obsidian provenances and water contents within a single obsidian provenance.
• Formation of Human Society and its Changes in the Northern Circum Japan Sea Area in Last Glacial Maximum

  The present research discussed the process of appearance of Upper Paleolithic in Japanese Archipelago, through examine the northern route for the first modern human in the Last Glacial from Archaeological and Anthropological point of views. Hunter-Gatherer were targeted group mammals that inhabited cold grass-land and open forests during the LGM, particularly about 26,000-22,000 cal yr BP. However, the change at the LGM was not just a replacement of the small flake industry by microblades, but a divergence of the Flake-based, Blade-based, and Microblade-based toolkits. In addition with these result, the late Pleistocene radiocarbon chronology of the Transbaikal to conclude that humans completely abandoned the area between 25,000 and 22,000 cal yr BP, suggested us Hokkaido to serve as a refuge and the origin of microblade technology.
• An exploitation of new obsidian hydration dating toward the establishment of reliable chronology in prehistoric sites and the estimation of paleoclimatic conditions

  The goal of present research is to explore the new research direction of obsidian hydration dating (OHD). Toward the establishment of reliable chronology of prehistoric sites and estimation of paleoclimatic conditions, I examined as to whether and to what extent OHD works. A procedure to choose reliable measurement was proposed through a systematic comparison of variation in rim thicknesses within and between the specimens. Site dates were estimated by using the mean rim thickness that was systematically chosen from the samples. The mathematical formula to estimate the effective hydration temperature (EHT) proposed by Rogers (2007) was employed. The difference between EHT for studied early Holocene site and mean temperature based on the local meteorological data indicated that both Holocene climatic maximum and changes in depths of samples in response to the accumulation of sediments had effects on EHT.
