Kochi Prefecture | The Home of Sakamoto Ryoma & Niyodo Blue

Located in Kōchi-ken’s Ino Town, Nikobuchi is a popular waterfall basin with a vibrant blue hue to it.

When I started making content online all those years ago, one of the goals I set for myself was to visit each and every one of Japan’s 47 prefectures. I had originally planned to complete the list by the end of 2020, but the pandemic hit and threw a wrench in those plans. After that, my travel schedule gradually became dominated by a never-ending stream of FAM trips for paid promotions with local governments. Realizing I’d never reach my goal at that pace, I made a concerted effort to get back on track and wrap things up. Kochi Prefecture, which I visited in June of 2025 and which is the focus of today’s article, was the final destination on my list.

To be frank with you, I’m a bit ashamed that it took me so long to get to Kochi Prefecture. Easily one of the most beautiful places I’ve visited, Kochi is rich in samurai history, breathtaking nature, and options for outdoor activities. Located on the Pacific Ocean side of Shikoku, the smallest of Japan’s four main islands, the prefecture is admittedly a bit remote compared to more accessible destinations like Kyoto and Osaka. That said, the ruralness of the region is actually one of Kochi’s main draws. Unlike other spots that are besieged by overtourism, you’re unlikely to encounter many other travelers during your visit.

Historically speaking, Kochi was known as Tosa Province, a feudal domain ruled for centuries by the Yamauchi clan. Centered around Kochi Castle, the domain played a notable role during the Edo period (1603–1868) and later emerged as a hotspot of political reform in the lead-up to the Meiji Restoration. Tosa was home to influential figures like Sakamoto Ryoma, a visionary samurai who helped broker the alliance that ultimately brought an end to the Tokugawa shogunate. Even today, you’ll find his legacy honored throughout the prefecture, from statues and museums to casual nods in local tourism. This deep connection to history gives Kochi a distinct identity that feels both proud and enduring.

In addition to its history, Kochi is blessed with some of the most stunning natural landscapes in all of Japan. The prefecture is home to the Niyodo River, often praised for its remarkably clear waters, which cut through lush gorges and tranquil valleys. This river, along with the pristine Shimanto River, offers countless opportunities for outdoor adventures like kayaking, canyoning, and riverside hikes. Further inland, the untouched heart of central Shikoku reveals a rugged, mountainous terrain that feels worlds away from Japan’s urban centers. With dense forests, misty mountains, and barely a soul in sight, this region is ideal for travelers seeking solitude and raw natural beauty.

All in all, while it takes quite the commitment to explore a location like Kochi Prefecture, it’s exactly the kind of destination I love to recommend. You’ll need to budget a few days to get the most out of your visit (especially when you factor in the travel time), but this prefecture on the far-flung coast of Shikoku is bound to be one of the highlights of your trip. Whether you’re a history buff, outdoor enthusiast, or die-hard foodie, Kochi has something for you. As you’ll see in the lengthy exposé below, there’s a surprising amount of depth to this still-yet-to-become famous corner of Shikoku—so much so that I almost want to gatekeep it.

How to Get There

Let’s take a quick second to cover some key logistics first before going into the subsequent subsections on what to see and do in Kochi Prefecture. For most people, the easiest way of getting to Kochi will be to fly down from somewhere central like Tokyo to Kochi Ryoma Airport. Situated on the outskirts of the prefectural capital, this airport has direct flights to and from Kochi City. While that does mean you can’t milk your Japan Rail Pass or regional alternative, it is the most expedient means of reaching Kochi Prefecture if you’re not already on Shikoku.

As long-time readers will know, I really don’t like flying because, even if it does get you there faster, the entire journey gets chopped up into little segments. In comparison to the chaos of getting to the airport, waiting at the gate, boarding the flight, etc., I greatly prefer a long train ride as I can get something actually done en route. For those of you who are similarly minded or who have rail passes, know that Kochi can actually be reached by train. As you’ll see in Jorudan or a similar service, you’ll first need to take the bullet train to Okayama Station, then transfer to a limited express train to reach Kochi Station.

One bit of advice for when you actually do get to Kochi Prefecture is to plan your outings for the subsequent day on the night before. Simply put, the bus and train departures, especially to some of the more remote regions in Kochi, are not what they are in more populated prefectures. As I note in this guide about traveling in Japan’s countryside, missing a connection can either set you back hours at best or, at worst, leave you stranded somewhere with no other means of getting back to civilization. Thus, you’d be wise to do your homework and plan transportation well in advance.

Historic Kochi Castle

Unlike some of the other samurai strongholds which are set in the middle of historical townscapes, Kochi Castle is located right in the prefectural capital of Kōchi-ken. It is one of twelve surviving keeps in all of Japan.

Let’s start by taking a look at one of the prefecture’s most iconic spots: Kochi Castle. This stronghold is one of just a handful of original castles in Japan that still retains both its main keep and surrounding palace structures. Construction began in the early 1600s under the orders of the first lord of the Tosa Domain shortly after the Battle of Sekigahara. While a fire destroyed much of the castle in the 1700s, it was painstakingly rebuilt in its original style using traditional techniques. Today, Kochi Castle stands as a rare and well-preserved example of a wartime fortification, offering a real sense of what feudal Japan might have looked like at the time.

For those who make the effort to climb up to where the castle’s keep is located, you’ll be rewarded with much more than just a pretty view. The expansive grounds are surprisingly lush, especially considering their central location within Kochi City. Inside, the wooden interiors of the main keep and connected buildings give off a distinctly historical atmosphere, complete with creaky floorboards and narrow stairwells. There’s plenty of information posted in English, and several displays explain the castle’s significance as the administrative and residential heart of the Tosa Domain. From the top, you’ll also get a nice panoramic shot of the city skyline and surrounding hills.

Getting to Kochi Castle is thankfully quite easy, especially if you’re already staying in or around central Kochi City. The castle is located just a short walk from the Harimayabashi and Obiyamachi shopping arcades, and it’s well-signposted from most central hotels. While you could easily walk there if you wished, the site is also served by one of the city’s retro streetcars. When visiting, be sure not to miss the Kochi Castle Museum of History, which is located right across the road and is a treasure house of lore about Kochi Prefecture.

The Boozy Hirome Market

Unlike many traditional market in Japan, Kochi’s notorious food court is a place where the population can come together and enjoy a drink or two during any time of the day.

Located right by Kochi Castle is the Hirome Market. Pictured above, this spot is cherished by Kochi people and serves as a sort of communal “living room”-like third space where locals and travelers alike gather to eat, drink, and be merry. Though technically just a food court, Hirome Market is unlike any other in Japan. It’s loud, boozy, and wonderfully chaotic — something between a festival and a street party, all under one roof. Walk in and you’ll be hit with the sounds of clinking glasses, sizzling grills, and the murmur of half-tipsy conversations echoing off the walls.

The market is made up of a densely confusing grid of food stalls and tiny shops selling everything from souvenirs to local produce. There’s no central order to things, which is part of the charm. You grab whatever looks good, whether it’s Kochi’s famed Katsuo-no-Tataki (seared bonito), gyoza fresh off the griddle, or something you can’t quite identify but smells amazing, then find a seat at one of the shared tables. Don’t be surprised if you end up striking up a conversation with the group next to you. People are friendly here, and more than a few will have a drink in hand even if it’s barely past noon.

Hirome Market is also one of those rare places in Japan where daytime drinking doesn’t raise an eyebrow. In fact, it’s kind of expected. Salarymen on their day off, aunties catching up with friends, and tourists just soaking it all in seem to be nursing a cold beer or a cup filled with a brew from one of Kochi’s old sake breweries while picking at their food. The atmosphere is equal parts rowdy and relaxed, and it stays lively well into the evening. Whether you’re in the mood for a quick bite or a slow, boozy lunch, Hirome Market is an essential stop when visiting Kochi City.

Katsurahama Beach & the Pacific Ocean

To the south of the city center is Katsurahama. This part of the prefecture sits on the coast of the Pacific Ocean and has long been known as a popular moon viewing spot.

In addition to the two titans mentioned thus far, one of the other famous attractions in Kochi City is Katsurahama Beach. Facing the Pacific Ocean and shaped by the powerful Kuroshio Current since ancient times, this scenic stretch of the coast has long been a favorite for both locals and visitors alike. Unlike many of Japan’s beaches, swimming here is prohibited due to the strong waves and undertow, but the dramatic views more than make up for it. The curved shoreline, framed by rocky outcrops and windswept pines, feels almost cinematic.

One of the first things you’ll notice upon arrival is the towering bronze statue of Sakamoto Ryoma looking out to sea. Erected in honor of Kochi’s most famous son, the statue is an iconic image and a popular photo op. If you’re not familiar with Sakamoto Ryoma yet and his key historical role, don’t worry. Just up the hill from the beach is the Sakamoto Ryoma Memorial Museum, which does a solid job of chronicling his life and the crucial role he played in the Meiji Restoration. The museum is modern and well laid out, with plenty of artifacts and exhibits that help put the man’s legacy into context.

Down by the beach itself, you’ll find the small but culturally significant Watatsumi Shrine tucked into the rocks. This seaside shrine is dedicated to the deity of the sea and offers a tranquil counterpoint to the often windy and wild shoreline. It’s a great little detour if you’re already wandering the area and want a quick spiritual breather with a view. Nearby, the adjacent Katsurahama Aquarium offers a modest but fun way to spend an extra hour. It features regional marine life and has a bit of retro charm to it, making it a surprisingly endearing stop.

Getting to Katsurahama from central Kochi is pretty straightforward. The fastest option is the Kochiken Kotsu bus from the JR Kochi Station, which takes about 35 minutes and costs 800 yen one way. Alternatively, the My Yu Bus runs via Mt. Godaisan (we’ll cover this in a second) and takes about an hour, with a 1-day pass priced at 1,300 yen. Once you arrive, the nearby RYOMA YUME HIROBA complex is a convenient spot to grab a bite, browse for souvenirs, or just kill some time before catching your ride back.

Kochi City’s Other Sightseeing Spots

Katsuo-no-Tataki is the pride and joy of the local Japanese population. Along with a visit to Chikurinji Temple, the botanical garden named after Tomitaro Makino and some of the other destinations in Kochi

First things first — if you’re going to be in Kochi, you absolutely must try Katsuo-no-Tataki. Officially designated as the regional meibutsu for this part of the country, the dish features thick slices of seared bonito served with various condiments like garlic, wasabi, and ponzu. To be totally transparent with you guys, I got so addicted to this dish that it was literally all I ate while in Kochi. Every single meal during my four-day stint in town was Katsuo-no-Tataki. It was just that good. You’d be a fool to visit Kochi Prefecture and not give it a shot.

My cravings for katsuo-no-tataki aside, there are a number of other locations in Kochi City that are worth checking out before venturing out to see some of the more rural attractions. First and foremost are the spots on Mt. Godaisan. Here, you’ll find Chikurin-ji, the 31st temple of 88 on Shikoku’s famed Ohenro pilgrimage. The temple grounds feature an interesting array of halls and structures, including a beautiful five-storied pagoda. There is also a peaceful garden area that makes for a nice place to pause and take in the atmosphere.

Right next to Chikurin-ji is the Makino Botanical Garden, a spot that often flies under the radar but is absolutely worth a visit. Named after local-born botanist Dr. Makino Tomitaro, the garden is home to thousands of plant species, many of which are native to Japan. The layout is spacious and thoughtfully designed, with seasonal flowers, walking paths, and even indoor exhibits that showcase doctor’s life and scientific contributions. Whether you’re into botany or just looking for a quiet, green escape from the city, this place delivers!

Finally, there is the Kochi Sunday Market. Running for over 300 years and stretching for more than a kilometer along the street leading up to Kochi Castle, this open-air market is a local institution. Every Sunday, hundreds of vendors set up shop to sell everything from fresh produce and regional snacks to handmade crafts and antiques. It’s the kind of place where you can grab a bag of yuzu, pick up a vintage kimono, and snack on something deep-fried all in the same breath. The vibe is laid-back and friendly, making it a fun way to mingle with the local population of Kochi.

The Niyodo River & Nakatsu Gorge

This gorge connects to Kochi Prefecture’s most iconic, cobalt-blue river and is absolutely breathtaking to behold. Both sides of the gorge sport rich nature and there are a few Japanese shrines and whatnot along the way to check out as well as a waterfall.

Let’s now venture out of the inner city and explore some of the more remote wonders of Kochi Prefecture. One of the most breathtaking natural spots in the region is the Niyodo River. Famous for its unreal clarity and vibrant turquoise color, commonly referred to as “Niyodo Blue,” this river is located to the west of the prefecture’s capital city and flows through a rugged landscape of gorges, waterfalls, and dense forests. It’s the kind of place that feels untouched by time, where even just standing by the water can feel like a moment of quiet awe.

Of all the places to take in the beauty of the Niyodo River, Nakatsu Gorge stands out as a highlight. This narrow ravine is carved out by the river itself and is filled with mossy rock walls, cascading falls, and suspension bridges that seem to float above the blue. A well-maintained walking trail follows the river through the gorge, making it easy to experience the scenery up close without needing any advanced hiking skills. Along the way, you’ll also find a few shrines tucked into the cliffs, adding a nice spiritual touch to the already surreal landscape. There is even a craft beer spot 45 minutes into the gorge!

After a solid hike through Nakatsu Gorge, nothing beats soaking your muscles in a hot spring. Right at the entrance sits Yu-no-mori, a charming onsen hotel offering day-trip access to its outdoor baths. Its natural spring water is gentle on the skin and perfect for unwinding after walking the trails. If you’re looking to turn it up a notch, Niyodo Adventure in the nearby town of Niyodogawa runs guided canyoning and pack rafting tours along the river. These limestone-walled waterways let you jump, paddle, and explore hidden waterfalls, with full gear provided and English-speaking guides available, all in a jaw-droppingly beautiful setting.

Photographers in particular will find plenty to love here, as the contrast between the lush greenery and the otherworldly water makes for stunning shots. It’s also a great place to simply disconnect for a while. There’s very little cell service in this area, and that’s honestly part of the appeal. The combination of rushing water, birdsong, and the occasional temple bell in the distance creates a kind of natural soundtrack that’s hard to come by elsewhere. Just be prepared to walk a lot as getting around this part of Kochi Prefecture is pretty painful.

On that note, allow me to reiterate again that buses from the nearest station are extremely infrequent, and missing one can throw off your entire day or even leave you stranded. If you’re planning to rely on public transport, you’ll need to research departure times in advance and build your entire itinerary around them. Better yet, consider renting a car for the day. It gives you much more flexibility and saves you from the stress of potentially missing a rare connection.

The Lazy Shimanto River

The Shimanto River is the longest river on the island of Shikoku and flows for nearly 200 km through the countryside of Kochi Prefecture. It’s known for its Chinka-bashi which were designed to not wash away durning floods.

In addition to the cobalt blue Niyodo River, the Shimanto River is the other major river in this part of Shikoku. Often called the last clear stream of Japan, the Shimanto River flows for nearly 200 kilometers through a serene and mostly undeveloped valley. Unlike many of Japan’s other major rivers, it has no dams along its main course, which helps preserve its natural character. The slow-moving water, lush scenery, and quiet rural charm make it an ideal place for those looking to disconnect and take things at a slower pace.

One of the most unique features of the Shimanto River is its series of chinka-bashi, or submersible bridges. These flat, rail-less crossings are designed so that water can pass overhead during floods rather than sweep them away, and they have become iconic symbols of the area. Whether you are cycling along the river or just driving through, spotting these bridges or walking across one if you’re brave enough is a memorable part of the experience. They are also a favorite subject for photographers and drone pilots looking to capture that classic Shimanto shot.

The river is also a hub for low-key outdoor adventure courses. Canoeing, kayaking, and stand-up paddleboarding are all popular here, with local outfitters offering rentals and guided tours. If you are not into water sports, there are plenty of riverside trails and quiet country roads perfect for walking or cycling. Many travelers also enjoy stopping by the small villages scattered along the riverbanks, where you can find cozy cafes, small shops, and the occasional roadside stand selling handmade goods or seasonal produce.

Getting to the Shimanto River area from Kochi Station can take a bit of effort depending on where you’re coming from. The easiest access point is usually around Nakamura Station, which is connected to Kochi City by limited express train and takes about two and a half hours one way. From there, buses and rental bikes are available, but service can be sparse and connections are not always ideal. As with many parts of rural Kochi, having a rental car will open up a lot more flexibility and save you from the headaches of infrequent public transit.

Kochi’s Yosakoi Festival

Every year in early August, this part of the island of Shikoku celebrates the Yosakoi Festival. Unlike other festivals in the Land of the Rising Sun, this one encourages crowd engagement.

Every August, Kochi City comes alive with the vibrant energy of the Yosakoi Festival. First held in 1954, this event has since grown into one of Japan’s most unique and high-octane traditional festivals. Teams of dancers flood the streets, decked out in colorful costumes and moving to an upbeat remix of “Yosakoi Bushi,” a traditional folk song that’s been given a modern twist. The result is a fast-paced, high-energy celebration that blends old and new in a way that feels distinctly Kochi and draws many revelers from the local population here in Shikoku every year

Unlike more rigid festivals elsewhere in Japan, the Yosakoi Festival encourages creativity and crowd engagement. Participants come from all over the country and even abroad, and you’ll see everything from classic yukata to funky, customized uniforms that reflect each team’s theme. The only real rules are that dancers must carry wooden clappers called naruko and incorporate some element of the Yosakoi Bushi or other Japanese traditional folk songs into their routine. The performances spill out onto multiple stages and parade routes across the city, creating a carnival-like atmosphere.

Even if you’re just there as a spectator, the festival is a blast. Food stalls line the streets, offering everything from Kochi specialties like that Katsuo-no-Tataki I’m so addicted to, to the usual festival staples like yakisoba and shaved ice. The crowds can get intense, but the vibe stays festive and friendly. If your timing lines up and you’re in town during August, catching the Yosakoi Festival is easily one of the most memorable things you can do in Kochi Prefecture.

Epic Cherry Blossoms

Hyotan Sakura is a well known tree in the central parts of Kochi Prefecture that is absolutely breathtaking during the springtime. It’s just a bit north of Kochi’s iconic cobalt-blue river

At the risk of jumping seasons, no feature on Kochi would be complete without mentioning the prefecture’s amazing cherry blossoms. While there are a number of spots, one of the most unique has to be the Hyotan Cherry Blossom Tree or “Hyotan Sakura” in Japanese. Found in the mountains of Sakawa Town, this lone tree is said to be over 500 years old and is notorious for blooming earlier than most other trees in Japan, often hitting full bloom in mid to late March. Surrounded by farmland and rolling hills, the setting is pure countryside Japan.

Getting to the Hyotan Sakura isn’t exactly straightforward, but it’s doable with a bit of planning. The tree is located in Sakawa Town, about an hour west of Kochi City by train. You’ll want to take the JR Dosan Line to Sakawa Station, which is the closest stop. From there, it’s another 20 to 30 minutes by car or bus into the rural hills where the tree is located. Unfortunately, public transportation doesn’t run directly to the site but you can get close enough. From there, you’ll just need to hike north up into the hills to where the Hyotan Sakura is located.

Other Nearby Attractions

Situated up on the highest peaks of the island of Shikoku in the highlands between Ehime and Kochi, Shikoku Karst is a breathtaking open grassland that’s dotted with a number of limestone outcrops.

Kochi Prefecture is a place that can be visited all on its own without the need to see anything in the neighboring prefectures. Still, if you want to see more of the Japanese countryside and explore more of what the island of Shikoku has to offer, consider putting off that flight back to Tokyo or Osaka and instead heading west to Ehime Prefecture, where you’ll find Matsuyama City, or north to Tokushima for the extremely remote Iya Valley. Honestly, there is so much on offer in Shikoku that I could entirely derail this article with recommendations.

Known as one of Japan’s three major karst landscapes, Shikoku Karst stretches across the highest point between Kochi and Ehime and sits at an elevation of over 1,000 meters. The area is dotted with weathered limestone outcrops and open grasslands that feel more like something out of rural Europe than Japan. On clear days, the panoramic views are absolutely phenomenal, with rolling hills and endless sky in every direction. It’s especially striking in the early morning or late afternoon when the light adds a golden hue to the already surreal terrain.

That said, Shikoku Karst is not the easiest place to reach without private transport. Public transit is virtually nonexistent up in the highlands, so a rental car is basically essential if you want to enjoy the area properly. The roads are winding and narrow in parts, but the drive itself is a huge part of the appeal. There are also a few roadside stops and small lodges where you can grab a bite or even stay overnight. If you’re after big skies, wide-open landscapes, and a taste of rural Kochi at its most dramatic, this is the place to go.

In addition to Shikoku Karst, Kochi Prefecture is also home to other natural wonders like Nikobuchi and Ryugado Cave. The former is a sacred, waterfall-fed pool tucked into a lush gorge, well known for its deep blue color and mystical atmosphere. A steep staircase leads down to the water, adding to its secluded feel. The latter, on the other hand, is one of Japan’s top limestone caverns, stretching over four kilometers in total, with about one kilometer open to the public. Inside, you’ll find dramatic stalactites, narrow tunnels, and even archaeological relics from early Japanese civilization.

Finally, while Kochi is best known as a spring and summer destination, the mountains of the prefecture come alive during the fall when the autumn leaves starts to turn. Places like the Shimanto River valley, Nakatsu Gorge, and the highlands around Shikoku Karst offer some of the best leaf-peeping in western Japan, with brilliant reds and golds set against crisp blue skies. It’s a quieter season too, making it an ideal time for travelers who want all the beauty of the island of Shikoku without the crowds in Kyoto.

Until next time travelers…
