Overview of the laboratory
-
Ocean surface occupies about 70% of the Earth's surface. Utilizing the vast ocean, we research and develop sustainable marine food and renewable energy production systems in harmony with marine ecosystem . We hope to contribute to Japan becoming a true maritime nation by developing technology that allows us to maximize the various resources of the ocean.
