Shikoku is weird. I mean that in the best way possible, but let’s be honest: if you look at a standard map of Shikoku island Japan, you’re seeing a massive lie of omission. You see four prefectures—Ehime, Kagawa, Tokushima, and Kochi—and a whole lot of green space. It looks manageable. It looks like a weekend trip.
It isn't.
Most people treat Shikoku like the "other" Japan, the one they’ll get to after they’ve done the Tokyo-Kyoto-Osaka golden route. But when they finally pull up a map, they realize the scale is totally deceptive. This isn't just a small island off the coast of Honshu. It’s a rugged, mountainous fortress that’s been culturally isolated for centuries, and that isolation has created something you simply can’t find in the neon chaos of Shinjuku.
The Topography Nobody Warns You About
Open up Google Maps or a physical topographical map of Shikoku island Japan. Notice the center? It’s almost entirely dark green and brown. That’s the Shikoku Mountains, often called the "Tibet of Japan."
Mountains dominate about 80% of the landmass. This isn't just a fun fact for geographers; it dictates everything about how you move. If you’re planning to drive from Takamatsu in the north to Kochi in the south, a glance at the map makes it look like a straight shot. In reality, you’re looking at a series of tunnels, winding cliffside roads, and massive elevation changes.
The Iya Valley is the perfect example. On a flat map, it’s just a tiny spot in Tokushima Prefecture. In person, it’s one of the three "hidden" regions of Japan. Historically, the defeated Heike clan fled here after the Genpei War in the 12th century because the terrain was so inaccessible that the imperial army couldn't find them. Even today, navigating the "vine bridges" (Kazurabashi) feels like stepping into a different century.
Why does this matter? Because travel time on Shikoku is roughly double what you think it is. You aren't cruising on the Shinkansen here. Aside from a tiny stretch of high-speed rail that doesn't really count as a "bullet train" in the traditional sense, you’re relying on the Limited Express trains like the Shiokaze or the Nanpu. They tilt. They lean into the curves. It’s an adventure, but your map won't tell you that you'll be spending four hours going a distance that would take one hour in Nagoya.
Decoding the Prefectures: More Than Just Borders
When you look at a map of Shikoku island Japan, you’ll see the four corners. Each has a personality that feels like a different country.

Kagawa: The Udon Kingdom
Up in the northeast, Kagawa is the smallest prefecture in Japan by land area. It’s compact. It’s flat-ish near the coast. It’s basically obsessed with Sanuki Udon. There are more udon shops here than convenience stores. Seriously. If your map doesn't have a star on Ritsurin Garden in Takamatsu, throw the map away. It’s one of the most significant historical gardens in the country, featuring a backdrop of Mount Shiun that uses a technique called "borrowed scenery."
Ehime: Oranges and Ancient Springs
Moving west, you hit Ehime. This is the land of citrus and Matsuyama. Matsuyama Castle is one of the few original-construction castles left in Japan—not a concrete reconstruction from the 60s. Then there’s Dogo Onsen. The main building (Honkan) supposedly inspired the bathhouse in Studio Ghibli’s Spirited Away. When you look at the map of the northwest coast, you see the Shimanami Kaido. This is a series of bridges connecting Shikoku to Honshu across the Seto Inland Sea. It is, hands down, the best cycling route in the world.
Kochi: The Wild Frontier
Kochi is the rebel. It’s the largest prefecture on the island and faces the Pacific Ocean. While the rest of Shikoku feels tucked away, Kochi feels exposed and vast. The Shimanto River is here. It’s famous for being the "last clear stream in Japan" because there are no dams on its main course. On a map, you’ll see it meandering through the southwest. It’s where you go to disappear. The people here are known for being heavy drinkers and incredibly welcoming—a trait they call Tosa-ben hospitality.
Tokushima: Whirlpools and Dance
On the eastern edge, Tokushima is your gateway if you’re coming from Osaka or Kobe via the Naruto Bridge. The Naruto Whirlpools are a literal geographical phenomenon caused by the tide moving between the Pacific and the Inland Sea. They can be 20 meters wide. Also, every August, the whole prefecture turns into a giant party for the Awa Odori dance festival.
The 88 Temple Pilgrimage: A Circular Map
You cannot talk about a map of Shikoku island Japan without mentioning the Ohenro. This is a 1,200-kilometer loop that hits 88 Buddhist temples associated with the monk Kobo Daishi.
Most maps show the route as a neat circle. It isn't. It’s a jagged, grueling trek that takes about 40 to 60 days to walk.
- Temples 1-23: The "Path of Awakening" (Tokushima)
- Temples 24-39: The "Path of Ascetic Training" (Kochi)
- Temples 40-65: The "Path of Enlightenment" (Ehime)
- Temples 66-88: The "Path of Nirvana" (Kagawa)
Even if you aren't a pilgrim, the Ohenro defines the island's soul. You’ll see people in white vests (hakurei) and conical hats everywhere. They aren't just tourists. They are ohenro-san. The locals practice osettai, the tradition of giving gifts or food to pilgrims. It’s a level of kindness that feels almost jarring if you’ve just spent a week dodging crowds in Shibuya.

The Inland Sea vs. The Pacific Coast
There is a massive climatic and visual divide on any map of Shikoku island Japan.
The northern coast borders the Seto Inland Sea. The water is calm. There are thousands of tiny islands like Naoshima (the art island) and Shodoshima (the olive island). It looks like the Mediterranean had a baby with Japan. It’s peaceful, sunny, and dry.
The southern coast? That’s the Pacific. It’s raw. Cape Ashizuri and Cape Muroto are the two "horns" of Shikoku pointing south. These areas are prone to typhoons and feature dramatic, jagged rock formations. If you’re looking at a map and trying to decide where to stay, understand that the north is for relaxation and art, while the south is for surfing, whale watching, and feeling the power of the ocean.
Common Misconceptions About Getting There
You look at the map and see Shikoku sitting right there below Honshu. You think, "I'll just take the train."
Wait.
There is no Shinkansen (bullet train) to Shikoku. None. To get there by rail, you have to take the Sanyo Shinkansen to Okayama and then transfer to the Great Seto Ohashi Bridge line. The view from the train as you cross the bridge is spectacular, but it takes time.
Alternatively, many people fly into Takamatsu or Matsuyama. Or, my personal favorite, take the ferry. There’s a night ferry from Kobe to Takamatsu that is remarkably cheap and saves you a night on a hotel. Looking at a maritime map of Shikoku island Japan reveals dozens of ferry routes that most Western tourists completely ignore. The orange ferry from Hiroshima to Matsuyama is a classic shortcut that saves hours of backtracking through Okayama.

Actionable Tips for Navigating Shikoku
If you are actually planning to use a map of Shikoku island Japan to build an itinerary, here is the reality check you need:
- Rent a Car. I know, Japan is the land of trains. But Shikoku is the exception. If you want to see the Iya Valley or the Shimanto River, the bus schedules will break your heart. They run maybe three times a day in rural areas. An International Driving Permit and a rental car will change your life here.
- Focus on One Half. Don't try to "do" Shikoku in four days. You'll spend the whole time in a car. Pick the "North Loop" (Kagawa/Ehime) for art and history, or the "South Wilds" (Tokushima/Kochi) for nature and solitude.
- Watch the Tides. If you’re going to Naruto to see the whirlpools, your map won't tell you that they only happen at specific times. Check the tide tables online before you drive out there, or you’ll just be looking at very flat water.
- Buy a Rail Pass (Maybe). If you aren't driving, the "All Shikoku Rail Pass" is one of the best deals in Japan. It covers all the private lines and even some ferries, which the national JR Pass does not always handle well.
- The "Michi-no-Eki" Strategy. These are roadside stations. On your map, they might look like mere rest stops. They aren't. They are culinary hubs. The Michi-no-Eki in Shikoku often have better food (like seared bonito in Kochi or sudachi citrus products in Tokushima) than the restaurants in the city centers.
Next Steps for Your Trip
Stop looking at the big, zoomed-out map of Shikoku island Japan and start looking at the topographical layers.
Identify the specific "points of interest" that actually move you. If you want the "Old Japan" feel, circle Matsuyama and the Iya Valley. If you want the modern "Art House" vibe, look at the islands in the Seto Inland Sea like Naoshima and Teshima.
Your next move should be checking the ferry schedules between Okayama and Takamatsu, or Hiroshima and Matsuyama. These water routes are the "secret" passages that make Shikoku much more accessible than the rugged mountain interior suggests. Forget the fast-paced itinerary. Shikoku is meant to be traveled slowly, preferably with a bowl of udon in one hand and a paper map that you’re prepared to ignore when you see a beautiful, unnamed mountain road.
Download an offline map of the Kochi coastline before you go. Cell service is great in the cities, but once you hit those deep mountain valleys or the far-flung capes, you’ll be glad you have a digital backup for when the physical signs are only in kanji.
Shikoku is waiting. It’s rugged, it’s quiet, and it’s nothing like the map suggests. It’s better.
