In order to clarify the frequency and distribution of tsunami deposits from the Holocene in the southeast area of the Shizuoka Plain, Shizuoka Prefecture, we reconstructed the Holocene sedimentary environment of this area from two sediment cores (8 m long). The sediments consist mainly of dark blackish blue massive clay, interstratified with a 1-m-thick parallel-laminated clay layer and many thin sand layers with erosional bases. The characteristics of the sedimentary facies and the stratigraphic position of the Kikai-Akahoya tephra (ca. 7,300 cal. years BP) indicate that the sediments represent a lagoon-delta system and one transgressive-regressive cycle during the last 7,300 years. We detected two possible run-up tsunami deposits within the sediments with a probable depositional age of 6,000–3,000 cal. years BP. The upper part of the sediment cores seem to have suffer considerable disturbance by human activities which hinder us from assessing what happened in the last 3000 years.
