Why visit

• Sukumo is a port town at the western end of Kochi prefecture, facing the Bungo channel, and it is the last city before Cape Ashizuri and the southern tip of Shikoku. The Tosa Kuroshio railway ends here, and the town is a junction for the coast road and the ferry to the islands. It is a working place, and it is not on the usual Shikoku circuit.
• The harbour is the reason to stop. Sukumo lands katsuo, the skipjack tuna that is the soul of Kochi cooking, along with sardines, horse mackerel and the deep-sea fish of the channel, and the restaurants serve katsuo tataki, the seared fillet with salt or ponzu, at prices lower than in Kochi city. It is the best place in the prefecture to eat it.
• The town also has a castle site, a small museum, a temple with a fine garden and a set of old streets around the port, but the sights are modest. The real attraction is the coast: the road west to Ashizuri passes fishing ports, rock formations and the clear water of the Tatsukushi area, and the sunsets over the channel are the local spectacle.
• The third strand is the islands. Ferries from Sukumo reach the small islands of the Bungo channel, with fishing villages, beaches and a slow pace. They are rarely visited and they are the kind of place where the ferry timetable sets the day. The crossing is short and the water is clear.

Top places and highlights

The harbour

The port is the centre of the town, with fishing boats, the market and the ferry terminal, and the morning is the time to see it working. The restaurants around the quay serve the catch, and the katsuo is the local speciality. The sunset over the channel is the evening scene.

Katsuo tataki

The seared skipjack is the signature dish of Kochi, and Sukumo’s version is as good as any, with the fish landed locally and served with salt or ponzu. The restaurants near the port do it simply, and the prices are low. It is the reason to eat here rather than in the city.

The castle site

The town has the remains of a small castle on a hill above the harbour, with stone walls, a park and a view over the bay. It is free and quiet, and the walk up takes about twenty minutes. The site is a good place to understand the shape of the town.

The old streets

The streets between the station and the port have old houses, shops and a few temples, with the timber fronts of a port town. It is not a preserved district, but the scale is right and the morning market is real. The walk takes under an hour.

The Ashizuri coast

The road west from Sukumo passes the fishing ports and the rock formations of the Tatsukushi coast, with the clear water and the subtropical vegetation of the southern tip. Cape Ashizuri and its lighthouse are about an hour away, and the drive is one of the best in Shikoku.

The islands

The ferries from the port reach the small islands of the channel, with fishing villages and quiet beaches. They are rarely visited and the services are limited, so plan the return. The crossing is short and the water is clear.

The local food

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

Food and drink

• Katsuo tataki is the local speciality, served with salt or ponzu.
• The fish of the Bungo channel, including sardines and deep-sea species, are served at the port restaurants.
• The local vegetables and the citrus of western Kochi appear in the set meals.
• The sake of the Kochi breweries is dry and cheap, sold at the shops.

Getting there and around

• The town is on the coastal road, with buses to Ashizuri and the surrounding ports.
• The ferry terminal is near the station, with services to the islands.
• A car is the practical way to reach the coast and the cape.
• Kochi city is about three hours away by train, and the drive is faster.

Where to stay

• Business hotels near the station are the practical choice.
• A few small inns near the port serve fish dinners.
• The Ashizuri area has onsen inns with sea views.
• Book ahead in summer, when the coast is at its busiest.

• Summer is hot and humid, with the sea at its warmest.

• The coast road to Ashizuri is slow and winding; allow a full day.
• Cash is needed at the market and the small restaurants.
