Seaweed and seagrass communities were observed on the coast of Lake Nakaumi, Brakish water, Shimane, Japan. A total of 22 species of seaweeds and seagrasses were found on the coast. Their distribution and growing condition were influenced by the environmental factors of water, such as salinities (19.9-29.9 PSU) and illumination (0.4-24.0 klx at bottom) . Seaweed and seagrass communities were found only at depth of 0-3m in the study area, as the transparency was very lower. Particularly the transparency was lower at the southern part of Lake Nakaumi. The seaweed flora showed the species of a inlet type and the euryhaline species that tolerance to salt. The dominant species in the Lake Nakaumi were Sargassum thunbergii, Ulva pertusa, Gracilaria asiatica, and Zostera japonica.
