The Yaizu Plain in Shizuoka Prefecture, Japan, is located onshore of the Suruga Trough, which marks the convergent boundary between the Eurasian and Philippine Sea plates. The plain was inundated by tsunamis associated with the AD 1498 Meio earthquake (M 8.4) and the AD 1854 Ansei-Tokai earthquake (M 8.4); however, no previous study has investigated tsunami deposits in this area. Therefore, this study examined the distribution of possible tsunami deposits on late Holocene deposits, as observed in sediment cores (8–9 m long and 7 cm in diameter) collected at nine sites (elevations, 1.8–4.5 m) in the coastal area of the Yaizu Plain. At the northern area of the plain, the sediments in the cores are mainly back-marsh clayey deposits with thin gravelly channel-fill deposits. In the downtown area of Yaizu City, the sediments in the cores are mainly gravelly channel-fill deposits with thin backmarsh clayey deposits. The Kawagodaira pumice, which was erupted between 1,210 and 1,187 cal BC, was identified in the back-marsh clayey deposits at two sites. Possible tsunami deposits were not detected from all cores, over the past 3,200 years.
