Authors’ contributions:

YSh, SF, YSa, KT, DM, MY, EH, TK, and CC participated in the fieldwork. YSh took core logs at 12 locations and SF took core logs at one location. YSh and MSK performed SEM imaging of diatoms. YSa and YSh identified diatoms and interpreted paleoenvironments. YSh picked out plant macrofossils for radiocarbon dating, and YSa identified the materials. AM identified and interpreted plant macrofossils from MG10.KT taught YSh the procedure to constrain event ages by OxCal and YSh constrained them. YSh led the writing of the text and preparation of the figures. All authors read and approved the final manuscript.
