Highlights

About the Tosa Kuroshio Railway

The Tosa Kuroshio Railway is a third-sector railway operating lines taken over from JR. The Gomen-Nahari Line, linking Gomen and Nahari, is a relatively new line that opened in 2002, and because almost the entire route runs on elevated track, the views are excellent. The sections overlooking the blue Pacific up close are a succession of stunning scenery. The Nakamura-Sukumo Line, meanwhile, offers the nature-rich scenery of the Shimanto River basin and serves as transport for Shimanto sightseeing.

Stations Designed by Takashi Yanase and the Open-Deck Train

Each station on the Gomen-Nahari Line has a distinctive character designed by the manga artist Takashi Yanase, a Kochi native known as the creator of Anpanman, with a different charming figure at every station to brighten the journey. Searching for the characters, whose unique names play on the station names, is a fun part of the trip.

Some services also run an "open-deck car" with a viewing deck on the sea side, a popular train that lets you enjoy the Pacific panorama while feeling the sea breeze (operating days are limited, so check in advance).

The Pacific From the Window

The highlight of the Gomen-Nahari Line is above all the great Pacific panorama seen from the elevated track. In sections where blue sea and sky spread out, passengers sometimes cannot help but exclaim. The exhilarating view, looking down on the sea from higher than ground level, is an experience unique to this line.

Seasonal Enjoyment

Early summer through autumn, when the sea sparkles, is especially recommended, with exceptional views of blue sea and sky. The mild climate makes it comfortable to enjoy year-round. In summer, swimming beaches lie near the line, easy to combine with seaside leisure. Even in winter, mild Kochi often has clear-air days when you can see all the way to the horizon.

Access and Essentials

The starting point is Gomen Station, which connects with the JR Dosan Line. From Kochi Station, a train ride to Gomen is convenient and quick to transfer. The Gomen-Nahari Line runs from here toward Nahari. The Nakamura-Sukumo Line connects at Kubokawa Station with the JR Yodo and Dosan lines, making it a good pairing with Shimanto River sightseeing. Fares are settled by section as befits a local line, and free-pass tickets are sometimes offered, so check the official site for good value.

A Word of Advice

If you ride the Gomen-Nahari Line, choose a sea-side seat for the best Pacific views. On the elevated sections, you can enjoy the stunning blue sea filling the window. Takashi Yanase station characters differ at each station, so hopping off along the way to find them is a delight. Because services are limited on a local line, check the timetable and plan a relaxed rail journey.
