Wadomari (和泊町, Wadomari-chō) is a town located on Okinoerabujima, in Ōshima District, Kagoshima Prefecture, Japan.

Precipitation is high throughout the year, but is highest in the months of May, June and September.

As with all of Okinoerabujima, the town came under the administration of the United States from 1 July 1946 to 25 December 1953.

Sugar cane, sweet potato, and peanut farming are popular.

However, due to the lack of local jobs, there has been an outflow of residents.
