“…Sado Island (Matsue & Nasu, 1997;Nguyen et al, 1998) and the Hachirogata site (Yoshida & Takeuti, 2009) yielded 25% and 5% (Figures 4c and 5c) Cryptomeria pollen at 12,000 cal BP, respectively. These results suggest that the coast of the Tohoku region facing the Sea of Japan also served as refugia for small populations of C. japonica during the LGM.…”

The natural distribution of Japanese cedar (Cryptomeria japonica) has been disturbed by human activities, owing mainly to its value as timber; thus, its position in the vegetation zone of Japan is not clear. Therefore, it is important to determine the history of C. japonica forests before human influence. We reviewed the transitions in distribution and abundance of C. japonica in the Japanese Archipelago since the last interglacial period by using published pollen data. During the last interglacial, temperate deciduous broadleaf forests developed on northeastern Honshu Island, whereas on southwestern Honshu Island C. japonica populations increased, accompanied by warm-temperate evergreen broadleaf trees. During the first half of the last glacial period, C. japonica forests developed throughout the Japanese Archipelago except on Hokkaido. Thereafter, 60,000-30,000 years ago, C. japonica covered the area around Lake Biwa and the Izu Peninsula. During the Last Glacial Maximum, C. japonica was most abundant on the Izu Peninsula, and small refugial populations were located along the coast of the Sea of Japan from southwestern to northeastern Honshu, and along the Pacific coast of Shikoku Island. During the Middle Holocene, C. japonica populations increased rapidly in southwestern Honshu. Two thousand years ago, before the intensification of human activities, C. japonica was widespread in warm-to cool-temperate zones on the Sea of Japan side of Honshu, the Izu Peninsula, the Pacific coast of Shikoku Island, and Yakushima Island. This evidence indicates that C. japonica is one of the major tree species in the Japanese vegetation zone.

“…In recent decades, many studies have focused on reconstruction of past sea level changes and their influences on geomorphological changes. Some studies have successfully redrawn past coastlines and geomorphological changes based on reconstructed sea level changes (Stanley and Warne, 1994; Nguyen et al, 1998; Kato et al, 2003; Nahm et al, 2008; Yang et al, 2008; Ishihara et al, 2012; Tanigawa et al, 2013; Lambeck et al, 2014, and references therein; Katsuki et al, 2017; Xiong et al, 2020). Regarding Neolithic cultures, Holocene sea level transgression and climate changes were clearly linked to various early Neolithic settlements in East Asia (Zong et al, 2011; Li et al, 2018; Innes et al, 2019; Sun et al, 2019; Huang et al, 2021).…”

To explore sea level transgression in low-lying inland areas and its possible influence on prehistoric cultures, we investigated the physical and geochemical features of 20-m-long sedimentary cores from the previously seawater-filled Daesan Basin located in the middle reach of the present Nakdong River in Korea as proxies for seawater transgression deep inland areas due to Holocene sea level rise. Based on the relationships among grain size, total sulfur content (TS%), and carbon/sulfur (C/S) ratio, the first transgressive event was detected at ca. 8500 cal yr BP, caused by seawater influx along the present Nakdong River. Higher TS% (0.8–1%) and interbedded fossil oysters at 8000–6000 cal yr BP indicate marine environments, supporting a paleo-Daesan Bay with water depth of ~10–8 m. The common peaks in TS%, in both inland paleo-Daesan Bay and a present coastal area (Suncheon Bay) in southern Korea (e.g., at 3200 and 4700 cal yr BP), may indicate intervals of higher salinity, which suggests simultaneous responses to changes in sea level or hydroclimate. The duration of marine environment (paleo-Daesan Bay) in the remote inland from ca. 8000–3200 cal yr BP provides an analog for inland paleo-bay studies in East Asia.
