Operational details such as opening hours, admission fees, and train times can change. Prefer official pages and reconfirm before you travel (sources checked on 07 November 2026).

Why visit

  • Nakatosa is a small town on the coast of Kochi, at the mouth of the Shimanto river, and it is made of the old port of Kure and the villages along the estuary. It is a quiet place, with the river on one side and the Pacific on the other, and it is one of the best places in the prefecture to eat the katsuo.
  • The estuary is the attraction. The Shimanto, the last clear river in Japan, widens into the sea here, with the sandbanks, the reeds and the fishing boats, and the views from the bridges and the hills are the local scene. The sunsets over the estuary are the reason to stay.
  • The second is the port of Kure. The fishing harbour has the boats, the market and the restaurants, and the katsuo, the skipjack tuna, is landed and served as tataki, the seared fillet with salt or ponzu. The town is one of the places where the dish is at its best.
  • The third is the position. The town is on the coastal railway and the road between Kochi and Shimanto, with the river, the sea and the mountains around it, and it is a good base for the lower Shimanto and the Ashizuri coast. The food and the pace are the attraction.

The Shimanto estuary

The river widens into the sea here, with the sandbanks, the reeds and the fishing boats, and the views from the bridges and the hills are the local scene. The sunset is the best time. The estuary is the reason to stop.

The Kure port

The fishing harbour has the boats, the market and the restaurants, and the katsuo is landed and served as tataki. The morning is the time to see the boats. The port is the working heart of the town.

The katsuo tataki

The seared skipjack is the signature dish of Kochi, and the restaurants of the town serve it with salt or ponzu, at prices lower than the city. The fish is landed locally. It is the reason to eat here.

The bridges

The bridges over the estuary are the local landmarks, with the views up and down the river, and the walk or the drive across them is the best way to see the water. The sunset is the best time. They connect the two parts of the town.

The hills

The hills above the town give views over the estuary, the sea and the mountains, and the roads up are quiet and scenic. The walks are short. The autumn colour is fine.

The local food

Apart from the katsuo, the town serves the fish of the coast, the local vegetables and the citrus, along with the sake of Kochi. The food is plain and cheap. The sweets shops sell the traditional confections.

The access to the lower Shimanto
