TOC and TN contents rapidly increase from the depth zone of 610 to 540cm, with one reversal. The fossil pollen of cool-temperate deciduous trees also becomes abundant around this horizon. Subarctic conifers decrease from 730 to 540cm depth, with some fluctuations. Judging from these results and sediment ages estimated with \u00b9\u2074C dates and some marker tephras, the Last Glacial Maximum is reconstructed to have been around 20,000yrsBP. A warming suggested by increasing fossil pollen of cool-temperate deciduous trees started around 15,000yrsBP and lasted until about 11,000yrsBP (about 12,000calBP), being intercalated with some cooler phases. The warming was especially accelerated around 12,000yrsBP (14,000calBP). The cool phases recognized in the Late Last Glacial Age can be compared with the three Dryas periods in Northern Europe by pattern matching, but their ages are older by about 2,000 to 3,000 years. This dis-cordance may be a key to understand the mechanism which controls short-term climate changes. A slight cooling phase is also recognized around 9,000yrsBP. This phase is characterized by decreases in TOC and TN contents, but is not so clearly seen in pollen compositions.This phase may be correlated to the Boreal period in Northern Europe. This study presents the first detailed illustration of climate changes though the termination of the Last Glacial Age in central Japan. The studied core offers a useful standard of climate history, because it can be precisely correlated using the numerous marker tephras.", "subitem_description_type": "Abstract"}]},
