Directly beneath a large granite cliff lies a stone about 2 m above the sea, and 3 m in width, that looks like a mortar (usu). The Kuroshio Current, swirling in it, looks like a millstone being ground, giving it the name “usubae.” This is also the first place in Japan where the Kuroshio Current reaches the coast, and is believed to be the only place along the coast where its flow can be seen. Known nationwide as a mecca of fishing, it is also used as a filming site for movies.
