Abstract
Okinoerabu Island has a rich natural habitat and a unique culture that coexist, and it is very important that we tie these to the next generation. Regarding water resources, Okinoerabu Island is one of the coral upheaval islands and it has been historically difficult for residents to get water resources for their daily lives. There are used to be more than 130 springs using for residential lives, for drinking, cooking, washing clothes and taking bath, etc. Because the local government (China Town and Wadomari Town) developed the infrastructure in the early 1950s, most of the residents stopped using natural springs for their daily use. Now there are only a few records of natural springs in Okinoerabu Island and the residents might forget their history and live culture with the springs.
