Sediment cores were collected from the archaeological site dating from the Late Paleolithic to Jomon periods, now submerged beneath Lake Suwa, to reconstruct paleoenvironmental conditions such as lake-level fluctuations. Photo by Naoko Hasegawa (Ochanomizu University).

Fossil tree trunks from the Pliocene to Pleistocene (ca. 3.0–2.5 million years ago), observed in the riverbed of the Yasu River (Yoshinaga Member, Kobiwako Group).
Paleosols from the middle Miocene (approximately 9 to 12 million years ago), characterized by reddish-brown strata. These paleosols indicate the presence of seasonal heavy rainfall at that time (Seto Porcelain Clay Formation of the Seto Group, Toyota City, Aichi Prefecture).

These cores preserve a record of water level fluctuations and flood events over the past 25,000 years. Left: Event layers interbedded within lacustrine mud, along with trace fossils. Right: Fine rootlet fossils contained in the floodplain deposits. Scale bar represents 1 cm.
