Susaki City

Kochi Prefecture · City

Susaki City has prospered as one of Tosa's leading ports since the Sengoku period, and fishing, such as for bonito, is active. Deep inlets such as Uranouchi Bay and Susaki Bay line the coast. Traces of the Japanese river otter were found on the Shinjo River, so the city calls itself the "Otter Town." Nabeyaki ramen is a local specialty.
