Best things to do in Shikoku for nature-filled experiences

1. Walk down the historic vine bridges of Iya Valley

Deep in the heart of Tokushima Prefecture lies the remote Iya Valley, where steep forested slopes, rocky gorges, and icy emerald rivers await. Centuries ago, most of these were connected through vine bridges that helped transport people and goods. Legend has it that villagers from the olden days built these bridges in a way that could easily be cut down in the event of invaders.

There used to be over a dozen vine bridges, but now only three remain. The most popular one would be Iya Kazurabashi on the west side of Iya Valley. It spans 45 metres long and hangs 14 meters above the rushing waters. On the other side of the valley is Oku-Iya Niju Kazurabashi, a set of two parallel bridges. These bridges are traditionally made of wisteria quails, and are rebuilt every three years to ensure safety for both tourists and locals. 

2. Fly high above treetops and across the gorge

Another spectacular way to explore Iya Valley would be through Forest Adventure, an outdoor adventure park. It features a zipline that takes you through the woods and over the Iya River, making it a must-add on your list of things to do in Shikoku. With a length of 360 metres, it’s one of the longest in Japan and certainly a thrilling experience you shouldn’t miss!

3. Start your day catching a sea of clouds

Did you know that there’s also an unkai (sea of clouds) viewing deck in this part of Japan? The Hachigo-kiri Unkai is among the best Shikoku sightseeing spots. We recommend coming here early in the morning, just in time to witness a majestic panorama of clouds gathering right below the top of the mountains. Another pro tip would be scheduling your visit between March and April, and October and December, when the unkai is most frequent. 

4. Marvel in the breathtaking colours of Niyodo River

Now, let’s move on to Kochi Prefecture, where you’ll find the stunning Niyodo River. It’s often hailed as one of Japan’s most beautiful rivers for its pristine waters and surreal colour — that is, Niyodo Blue. While this soothing shade is present year-round, it’s most vibrant from November to March.

One of the best spots to bask in Niyodo Blue would be at Nikobuchi, a remote natural pool tucked away in the forest. It’s located upstream from the river, with its water source being the adjacent ever-churning falls. Since it’s a sacred site among locals, make sure to respect the rules such as no swimming and no rowdy activities. Other than that, feel free to take all the photos you want!

5. Go on a canyoning tour of Nakatsu Gorge

Within the area of Niyodo River is Nakatsu Gorge, an impressive natural wonder formed over 300 million years ago. Similar to Nikobuchi, it’s also a sacred site among the Japanese. Here, there are statues of the Seven Gods of Fortune standing amongst impressive boulders and ancient trees.

While Nakatsu Gorge has a relatively easy hiking course, why not opt for a canyoning tour? It takes about two hours, with an experienced local guide who will take you to the off-trail paths. This tour includes crossing amongst gigantic rocks and abseiling down the impressive cliffs. Afterwards, swim in the blue-green river, whose cold waters are especially inviting to those who come from countries with hot climates!

6. Cruise down Shimanto River

Another of the best things to do in Shikoku is visiting the Shimanto River — also a great example of unspoilt nature in Kochi Prefecture. Extending 196km, it’s the longest river in Shikoku, as well as the last free-flowing river in the country, given that it has no dams. It also holds the title of the Last Clear Stream of Japan, and is far removed from major cities.

Here, you’ll find forested canyons, rolling hills, and farmlands that go as far as the eye could see. The waters are relatively calm, making it ideal for various water activities. Take your pick between canoeing, riding a yakatabune (traditional roofed boat), or even stand-up paddleboarding! Wouldn’t it be great to bask in the lush scenery around you, along with the sight of fishes swimming below the river? 

7. Stroll around Ritsurin Garden

If you’re looking for leisurely things to do in Shikoku, how does visiting Ritsurin Garden sound? Nestled in the city of Takamatsu in Kagawa Prefecture, this sprawling park used to be private strolling grounds of feudal lords during the Edo Period. It opened to the public in 1875, and now remains to be a must-visit attraction.

It’s easy to see why Ritsurin Garden is one of the most scenic spots for traditional Japanese landscape gardening. Built near Mount Shiun, it boasts six koi ponds, a folk museum, a teahouse, rolling hills, and over a thousand pine trees. There’s no best time to visit, because it’s one of those Shikoku attractions that are lovely in any season. 

8. Experience glamping by the sea at Vessel Ochi

How about some coastal views for a change? If this is something you’d like for your ​​Shikoku sightseeing, we recommend spending a night or five at Vessel Ochi, a glamping area in east Kagawa. Travellers are guaranteed a relaxed time in nature with chic and convenient tent rooms and glamping lodges.

During the day, take your pick between munching on fresh seafood, enjoying the onsen, and swimming at the beach. The accommodations also offer a dazzling panorama of the Seto Inland Sea dotted with verdant isles. At nighttime, the glamping site is perfect for stargazing as well as a good ol’ bonfire. 

9. Take the famous Shikoku pilgrimage route

Dreaming of more natural sights, while also making time for self-reflection? Better add the Shikoku 88 Temple Pilgrimage to your bucket list! It’s among the few pilgrimages in the world that have a circular route. It covers 88 temples and sacred sites that the Japanese Buddhist monk, Kōbō Daishi, is said to have spent time in during the 9th century. 

While most henro-san (pilgrims) embark on this journey for religious purposes, there are also those who join to have an opportunity for spiritual rejuvenation. A stop that particularly left a mark on us is Yakuriji Temple in Kagawa. It’s the 85th temple of the pilgrimage and is situated close to the peak of Mount Goken. Legend has it that when Kōbō Daishi came to this temple to train in the Kokuzo-Gumonji method, five swords fell from the sky and a mountain deity appeared and said that the mountain will be a sacred place for Buddhism.  

Take your pick among the many things to do in Shikoku. Let Shikoku Tourism show you how it’s done.
