Best Things to Do in Kochi: The Complete Travel Guide (2026)

Kochi Prefecture sits on the southern coast of Shikoku, Japan’s smallest main island, and it is one of the country’s most rewarding and least-visited destinations. Known as the birthplace of Ryoma Sakamoto — the revolutionary samurai who helped topple the Tokugawa shogunate and open Japan to the modern world — Kochi combines rich historical legacy with dramatic Pacific coastline, pristine river systems, and a food culture built around the freshest seafood in Japan. For travelers willing to venture beyond the well-worn Kyoto-Tokyo corridor, Kochi delivers an authentic encounter with Japanese culture, history, and nature that is genuinely difficult to find elsewhere.

This guide covers the best things to do in Kochi: from the magnificent original castle that has survived four centuries intact, to the legendary Sunday Market that has run continuously for 300 years, to the spectacular Shimanto River — often called Japan’s last clear-water river. Whether you are planning a day trip from Matsuyama or a multi-day Shikoku itinerary, this guide has everything you need to make the most of your time in Kochi. For a broader Shikoku circuit, see our guide to the 88-temple Shikoku pilgrimage and the best things to do in Matsuyama.

Kochi Castle: One of Japan’s Twelve Original Castles

Kochi Castle is the undisputed highlight of the city and one of only twelve original castles remaining in Japan — meaning its keep was never destroyed and rebuilt but has stood continuously since 1753 (itself a reconstruction of the 1601 original after a fire). The castle sits atop Kochi’s central hill and is clearly visible from most of the city, its white-walled tenshu (keep) rising above a tiered system of stone walls and gates that remain almost entirely intact. Entry to the castle grounds is free; entry to the main keep costs ¥420.

Inside the keep, the museum displays original weapons, armor, documents relating to the Tosa domain, and extensive material on Ryoma Sakamoto — Kochi’s most famous son and one of the pivotal figures in 19th-century Japanese history. The views from the top floor of the keep encompass the entire city, the Kagami River valley, and on clear days, the Pacific coast to the south. The castle grounds include the only surviving example in Japan of a castle where both the main keep and the second bailey (ninomaru) structure are original, making it particularly significant historically.

Below the castle, Kochi’s famous Hirome Market (free entry, daily 7 AM–11 PM) is the city’s social hub: an indoor market-hall filled with food vendors, sake bars, and fresh seafood stalls where locals and tourists eat and drink together at communal tables. The speciality of the house is katsuo no tataki — fresh bonito (skipjack tuna) seared over burning straw and served with ginger, garlic, and ponzu — which is as central to Kochi’s identity as ramen is to Sapporo. Hirome is an essential Kochi experience at any time of day; it is particularly atmospheric in the evening when the tables fill and the sake flows.

The Sunday Market: 300 Years of Continuous Trading

The Kochi Sunday Market (Nichiyo-ichi) has operated without interruption since the early 18th century, making it one of the longest-running open-air markets in Japan. Every Sunday, approximately 500 stalls stretch for one kilometer along Otesuji — the broad boulevard leading to Kochi Castle — selling everything from fresh local vegetables and citrus fruits to hand-forged tools, antiques, potted plants, fresh fish, and traditional crafts. Browse Kochi tours and day trips on Klook to combine the market with a guided tour of the city’s highlights.

The Sunday Market is a genuinely living institution rather than a tourist attraction: most vendors are local farmers, fishermen, and craftspeople who have maintained stalls for generations. Prices are local prices, the atmosphere is friendly and unhurried, and the range of produce reflects Kochi’s exceptional agricultural diversity — the prefecture grows yuzu, mikan, ginger, myoga, soil-grown tomatoes, and an extraordinary variety of leaf vegetables that are barely known outside Shikoku. Arrive before 9 AM for the freshest selection; by noon the best produce has typically sold out. The market runs from approximately 5 AM to 6 PM.

A smaller version of the market — Tosa Ich — runs on the first Sunday of each month at the precincts of Chikurinji Temple (Temple 31 of the Shikoku pilgrimage) in the Godaisan area of eastern Kochi, combining the market with a visit to the temple’s excellent garden. Book accommodation in Kochi on Booking.com and plan to arrive on a Saturday so you can explore the Sunday Market first thing in the morning.

Katsurahama Beach and the Tosa Connection

Katsurahama Beach, 12 kilometers south of Kochi city, is one of the most famous beaches in Shikoku — not for swimming (a strong undertow makes it dangerous for swimming year-round) but for its dramatic setting: a curve of dark sand and pine-covered headlands framing a stretch of Pacific coast where the waves arrive unobstructed from the open ocean. The beach is particularly famous as a moon-viewing spot and features prominently in Japanese poetry and literature from the Tosa domain period.

On the headland above the beach stands a bronze statue of Ryoma Sakamoto — arguably the most famous piece of public sculpture in Shikoku — where he stands in characteristic pose, western boots over kimono, gazing out to sea toward the wider world he helped open Japan to. The Sakamoto Ryoma Memorial Museum is located a short walk from the statue and provides extensive English-language coverage of Ryoma’s life, the politics of the Bakumatsu period, and Tosa’s role in the Meiji Restoration. Entry: ¥700.

Katsurahama is also the home of Tosa fighting dogs (Tosa Inu), a breed developed in Kochi in the 19th century by crossing local dogs with imported European breeds including Great Danes and Mastiffs. The Tosa Inu Center at Katsurahama holds demonstration matches of traditional Tosa dog-fighting — a sport conducted under formal sumo-like rules where the dogs grapple without biting and the match is stopped if any dog shows injury or excessive stress — on the first Sunday of each month. The dogs are extraordinarily large and calm-tempered outside the ring.

Katsuo no Tataki: Kochi’s Most Famous Food

No visit to Kochi is complete without eating katsuo no tataki — seared bonito (skipjack tuna) that is the defining dish of the prefecture and one of the most distinctive regional foods in Japan. The preparation is specific: a large fillet of katsuo is briefly seared over a fire of burning rice straw (wara), which imparts a smoky aroma and chars the surface while leaving the center completely raw. The fish is then sliced thickly and served with ponzu soy sauce, fresh ginger, garlic, green onion, and thinly sliced myoga ginger. The result is simultaneously rich, fresh, smoky, and acidic — a combination unlike anything else in Japanese cuisine.

The best katsuo is eaten in Kochi from late March through August, when the fish migrate northward along the Kuroshio Current past the Tosa coast. Many restaurants allow you to watch the tataki preparation at the counter, where the whole ritual of the straw fire, the searing, and the rapid cooling is part of the dining experience. Hirome Market is the easiest place to try tataki; dedicated restaurants such as Tosa Ryori Tsukasa near Kochi Castle serve it in more formal settings with sake pairings.

Beyond tataki, Kochi’s food culture revolves around sawachi cuisine: large communal platters of sashimi, cooked fish, and local vegetables arranged on 40–50 cm lacquer plates, traditionally served at celebrations and festivals. The dorome festival in Akagawa — a competition to see who can drink the most fresh whitebait (shirasu) — is one of the more unusual annual food events in Japan.

The Shimanto River: Japan’s Last Clear-Water River

The Shimanto River, 196 kilometers long and draining much of western Kochi Prefecture, is known throughout Japan as the last truly clear-water river in the country — it has no major dam across its entire length, and its basin remains largely forested and undeveloped, keeping the water exceptionally clean. The river is famous for its unusual chinkabashi (submerged bridges): low concrete bridges with no railing, designed to go underwater during floods rather than resist the current, which gives the river’s middle reaches an otherworldly, open quality quite unlike any other river landscape in Japan.

The most popular base for Shimanto exploration is Shimanto City (formerly Nakamura), about two hours by bus from Kochi city. From here, tourist boats run on the river in summer, canoe rentals are available, and cycling routes follow the riverside for dozens of kilometers. The area is particularly beautiful in autumn when the riverbanks turn gold and the water reflects the surrounding hills.

Whale watching is available off the Tosa coast from April to October, with sperm whales, Bryde’s whales, and bottlenose dolphins regularly sighted. Tours depart from Tosa Shimizu port in the far southwest of the prefecture and run approximately four hours each way — a full-day commitment but one of the best whale watching experiences in Japan. Book through the Tosa Shimizu City tourism website or via activity booking platforms.

How to Get to Kochi

From Osaka, the fastest option is the Nanki or Shimanto limited express from Shin-Osaka to Okayama, then the Anpanman express from Okayama to Kochi (total approximately 2 hours 40 minutes; ¥8,000–9,000; JR Pass accepted). The train is named after Anpanman — the beloved Japanese cartoon character whose creator, Yanase Takashi, was born in Kochi — and the carriazgnes feature Anpanman illustrations throughout, making it a popular journey for families. Direct highway buses from Osaka to Kochi (3 hours 30 minutes, ¥3,400.–4,300) are significantly cheaper and run frequently from both Osaka Station and Namba.

From Matsuyama (the other major Shikoku city), the Shimanto express runs to Kochi in approximately 2 hours 30 minutes. Within Kochi, the MY Yugure tram system covers the city center (flat fare ¥200), buses reach Katsurahama (30 minutes, ¥620), and rental cars are recommended for exploring the Shimanto River and western Kochi. Browse Shikoku accommodation on Booking.com for hotels and ryokan in Kochi, Matsuyama, and the Shimanto area to plan a multi-city Shikoku itinerary.

When to Visit Kochi

The best time to visit Kochi is spring (March–May) or autumn (October–November). Spring brings cherry blossoms to Kochi Castle (typically late March, often earlier than mainland Japan due to the mild Tosa climate), warm weather suitable for outdoor markets and coastal walks, and the start of katsuo season. Autumn offers clear skies, cooler temperatures for hiking, and some of the finest river scenery in Japan as the Shimanto River basin changes color.

Summer in Kochi (June–September) is hot and humid, with significant typhoon risk in August and September, but this is peak katsuo season and the time when Yosakoi — Kochi’s explosive modern dance festival — takes place in mid-August. Yosakoi now attracts around 20,000 performers annually in Kochi alone.

Frequently Asked Questions About Kochi

Is Kochi Castle worth visiting?

Yes, Kochi Castle is one of the finest original castles in Japan and one of the most underrated. The combination of the intact castle grounds and the excellent museum inside the keep makes it a half-day attraction easily. The panoramic views of Kochi City from the top floor are excellent.

How long do you need in Kochi?

Two full days is a comfortable minimum for the city highlights. A third day allows a Shimanto River day trip.

What is the best food to eat in Kochi?

Katsuo no tataki is the essential experience. Also try katsuo dashi ramen, imokenpi (sweet potato strips), and sawachi sashimi platters. Kochi sake (Tosa Tsurane style: dry and clean) is also notable.

Can you do Kochi as a day trip from Osaka?

Technically yes, but 2 hours 40 minutes each way leaves only about 5 hours at the destination. An overnight trip or a 3-4 day Shikoku loop is strongly recommended.
