“…The light bands indicate that coarse marine sediments were repeatedly deposited at the site. The Holocene sea-level high stand reportedly formed since ~7000 cal yr BP along Japanese coasts (Tanigawa et al, 2013; Chiba et al, 2016) and along the east coast of China (Zong, 2004; Li et al, 2014). Thus, stabilization of sea level probably led to wave-induced retreat of a sandbar from 6600 cal yr BP to 5300 cal yr BP in the study area.…”

We present a multiproxy record using pollen, magnetic susceptibility, carbon isotopic composition, carbon/nitrogen ratio, and particle size of mid- to late Holocene environmental changes based on a sediment core from the Pomaeho lagoon on the east coast of Korea. The records indicate that climate deteriorations around 6400 cal yr BP and 4000 cal yr BP caused rapid vegetation changes in the study area, which were presumably attributable to low sunspot activity and strong El Niño–like conditions, respectively. These two cooling events were likely modulated by different climate mechanisms, as El Niño–Southern Oscillation activity began to strengthen around 5000 cal yr BP. These events may have had a substantial impact on ancient societies in the study area. Combining our results with archaeological findings indicated that climate deterioration led to drastic declines in local populations around 6400 cal yr BP, 4400 cal yr BP, and 4000 cal yr BP. Because of its high population, coastal East Asia (e.g., eastern China, Japan, and Korea) is particularly vulnerable to potential cooling events in the future. Therefore, there is a strong need for detailed paleoclimate information in this region.

“…The relationship between the palaeoenvironment and human activity have been actively studied (e.g., Masubuchi and Sugihara, 2010). Evidence of Holocene sea-level change is abundant on the eastern Kanto Plain (Endo et al, 1982; Ota et al, 1990; Chiba et al, 2016). The topography of the southern Kanto Plain has also been strongly influenced by Quaternary tectonics (Sugimura and Naruse, 1954; Yonekura, 1975; Matsuda et al, 1978; Nakata et al, 1980; Kaizuka, 1987; Shishikura, 2003, 2014; Hashima et al, 2016; Noda et al, 2018); for example, the present height of the deposits associated with the Holocene high stand increases toward the southern Kanto.…”

To help characterise the palaeogeographic and lacustrine environmental changes that resulted from the Holocene transgression and residual subsidence in the eastern Kanto Plain of central Japan, we analysed four drill cores and reviewed other core data from the southern part of the Lake Inba area. Fossil diatom assemblages yielded evidence of centennial-scale palaeogeographic and salinity responses to sea-level changes since the late Pleistocene. We determined that the seawater incursion into the Lake Inba area during the Holocene transgression occurred at approximately 9000 yr. We also recognised a late Holocene regression event corresponding to the Yayoi regression, considered to have occurred from ca. 3000 to ca. 2000 yr, and a subsequent transgression. Our data clarify some of the palaeogeographic changes that occurred in the Lake Inba area and document an overall trend toward lower salinity in the lake during the regression. In particular, the environment in Lake Inba changed from brackish to freshwater no later than 1000 yr. From the detailed palaeogeographic and palaeo-sea-level reconstruction, we recognised that residual subsidence occurred during the Holocene in this area. Thus, comparison of sea-level reconstructions based on modelling and fossil diatom assemblages is effective in interpreting Holocene long-term subsidence.

The so-called Yayoi regression in Japan is known as a relative sea-level lowering to m below T.P. (Tokyo Peil; Mean Sea Level of Tokyo Bay) during -cal kyr BP. However, the regions where this event occurred in the Japanese Islands and its continuous sea-level index points from verified regions have yet to be clarified. Lake sediments beneath the Innermost Tonegawa Lowland, deposited in response to a sea-level rise during -cal kyr BP, indicate a paleo-water depth of ca. -m. The sea-level index points of the lake sediments indicate that the sea level dropped to . m T.P. at . cal kyr BP, while the paleo-water depth estimated from plant macrofossils in the sediments is m. The amount of sea-level lowering is greater than the sediment compaction effect; moreover, no large tectonic movements have affected the region over the past years. These results demonstrate that the Yayoi regression occurred in the Innermost Tonegawa Lowland and that isostatic movements triggered by sediment loading might have brought about the observed lowering of sea level.
