Habitable Japan Sustainability of atmospheric and oceanic environment as a survival basis of island country Japan Grant-in-Aid for Transformative Research Areas (A) (2024–2028)

In this study, we will collaborate with fishermen who catch benthic crustaceans, such as those using crab pots in the Sea of Japan, to establish a wide-area ocean observation network extending from the coast of Hokkaido to Toyama Bay. We will conduct direct mooring observations of abnormal high waves. Furthermore, we will investigate the causal relationship with ocean fronts, which has not been fully explored to date, in an effort to clarify the generation mechanisms of abnormal high waves and the propagation processes of swells. If this research advances our understanding of the meteorological factors responsible for the so-called Yorimawari-nami (swell-type high waves that strike the coast of Toyama Bay), it is expected to make a significant contribution to the development of wave prediction systems and countermeasures against swell-related disasters, which have occurred frequently in recent years.
