Swells which invade Toyama Bay and cause wave disasters on the coast of Toyama Bay are called Yorimawari Waves and they are feared by the people in Toyama. The big wave disasters have been occured on the coast of Toyama Bay with a period of about 10 years. The need of more reliable wave prediction system are increasing under these circumstances. The basic matters on Yorimawari Waves and the wave prediction system were considered in this study based on the reserches on Yorimawari Waves which had been carried out in Toyama National College of Maritime Technology since 1967 and the consignment study from Japan Science and Technology Agency in 2010. They are as follows. (1) The discussion on the origin of name of Yorimawari Waves. (2) The discussion on generation mechanism of surf beat. (3) The discussion on the problems of current wave prediction system and proposal of wave prediction system based on wave observation. These results are reported in this paper.
