The manifestation of strong tsunami in historical time and in the Late Holocene was revealed in the deposits of coastal lowlands along the seacoast of the Eastern and Southern Primorye (from Udobnaya Bay to Anna Bay and Russian Island), the Sea of Japan, the Russian Far East. The lithological methods and diatom analysis were used for identifying of tsunamigenic deposits. The sources of the material and the parameters of the tsunami were estimated for different bays. Determination of the age of the events was based on radiocarbon dating of hosting organogenic deposits and tephrostratigraphy. The correlation of events was made between individual sections, and the results were compared with paleotsunami data over the region. It was found that in the Sea of Japan coasts, large tsunami occur every 200 years, though the situations of shorter recurrence interval for strong tsunami can not be excluded also.
