The coastal lowland of Minami Izu, Shizuoka Prefecture, Japan, has been inundated by tsunamis with wave heights of 5–6 m at least two times during the past 400 years. However, there have been no investigations of the frequencies or magnitudes of tsunami occurrences over long-term geological timescales in this area. We therefore conducted stratigraphic and paleoenviromental research on Holocene deposits based on a new outcrop and sediment cores (8–11 m long) from four sites in the lowland, examining the evidence for tsunami deposits. The Holocene sediments were deposited in a variety of coastal plain, shallow water, shoreface, backshore/dune, back marsh and floodplain. No any evidence for tsunami deposits was identified from the terrestrial deposits.
