Yokonami Sanri refers to a scenic spot of about 12 kilometers on the Yokonami Peninsula, which stretches from Susaki City to Tosa City, especially facing Uranouchi Bay. It is characterized by a complex and indented ria coastline, and you can enjoy the beauty of the calm bay, which is different from the open sea. A toll was once required, but it is now free, so you can enjoy driving and touring casually.

The Yokonami Kuroshio Line is an exhilarating driving course that runs from east to west across the Yokonami Peninsula, with a total length of about 18.8 kilometers. You can enjoy the feeling of driving on the sea as you drive along the undulating coastline while overlooking the majestic Pacific Ocean. There are several observation decks along the way, and from the Katabirazaki Observatory in particular, you can enjoy a 360-degree panoramic view of the entire ria coastline and the magnificent Pacific Ocean.

On the east side of the Yokonami Kuroshio Line is Seiryu-ji Temple, the 36th temple of the 88 Sacred Temples of Shikoku.
