Established with the objective of improving the livelihoods of local fishing communities, the Yamagata Prefectural Marine Education Research Group has continued in its efforts for more than 70 years. Along with the overall decline in the birthrate, there has been a decrease in the number of coastal elementary schools that promote marine education. Despite this situation, we continue to aim at the development of marine education in the local community, centered on the efforts of the Yamagata Prefectural Kamo Fisheries High School, and the creation of a nationwide network for marine education.
