01 ／ Bonito-flake workshop

A kettle room, smoking room, mold room and storeroom:four bonito-flake rooms in one building.

This one-story wooden workshop stands on the south side of a lot near the Usa fishing port. The Agency for Cultural Affairs writes that inside are four rooms, for kettle cooking, smoking, mold-setting and storage, and calls it the central facility of bonito-flake making. Built around 1947, it was registered in 2004 together with the preparation room and drying yard on the same lot.

02 ／ Yokonami mélange

Sediment scraped off as the plate subductsis spread here as a mixed-up layer of strata.

This is the coast of Goshikinohama (五色ノ浜) on the Yokonami Peninsula, in Usa-cho Ryu, Tosa. The Agency for Cultural Affairs writes that accretionary complex of the Shimanto Belt is distributed here, and that the peninsula is of world importance as the place where the theory that the archipelago grew by accretion of strata was proposed and proved. The prefecture's tourism site says the mixed-up strata (mélange) can be observed over a wide area.

03 ／ Tachibana grove

On a limestone outcrop,the tachibana are thought to have survived.

The grove is on a steep, rocky limestone slope on a small ridge on the east face of Mt. Matsuo in Kanbara. The Agency for Cultural Affairs writes that about 200 tachibana grow here, forming the largest-scale grove in Japan. One of the first places reported by Makino Tomitaro, who published the plant's scientific name, is thought to be this designated site.

01The Seiryuji Road of the Tosa Pilgrimage Road runs from Temple 35, Kiyotaki-ji, to Temple 36, Shōryū-ji, and the Agency for Cultural Affairs writes that the part crossing Tsukajizaka (塚地坂) keeps its old form. From the lookout on the pass you can see the village of Usa and Usa Bay; on rock blocks along the slope, distance-marker characters are carved, and roadside cliff Buddhas stand on the Usa side. The Tosa Pilgrimage Road was designated a National Historic Site in 2016.
02The Izumi Family Residence bonito-flake workshop in Usa is a Registered Tangible Cultural Property with a kettle room, smoking room, mold room and storeroom. The tourism association introduces Usa as the birthplace of "improved Tosa-bushi" bonito flakes, and the "production techniques of Tosa-bushi" were selected as a Registered Intangible Folk Cultural Property in 2021. The Yokonami mélange (2011) and the Tachibana grove on Mt. Matsuo in Kanbara (2008) are both National Natural Monuments.
03The tourism association introduces Kamata Isuji (鎌田井筋), an irrigation channel flowing through the Takaoka area, as built by Nonaka Kenzan and still in use after more than 350 years. It also introduces the tug-of-war begun to raise the spirits of its builders as today's Tosa City Otsuna Festival. In Ichinono stands the Junshin-do, a hall built by volunteers where the monk Junshin of the Yosakoi-bushi song was born.
