Shikoku
四国Shikoku is the smallest and least visited of Japan's four main islands, and this relative obscurity is central to its appeal. The eighty-eight temple pilgrimage circuit — the Shikoku Henro, established in honor of the monk Kukai — has drawn walkers for over a thousand years along a twelve-hundred-kilometer path that circumnavigates the island through mountain passes, river valleys, and coastal stretches of lonely beauty. To encounter a white-clad henro pilgrim on a forest trail, staff in hand, is to witness a form of spiritual practice that predates tourism by centuries and will outlast it.
Beyond the pilgrimage, Shikoku reveals itself slowly, rewarding patience. The Iya Valley in western Tokushima is one of Japan's last genuinely remote landscapes — a gorge of vertiginous depth spanned by vine bridges that sway above turquoise water, its scattered farmhouses accessible only by narrow mountain roads. Matsuyama, Shikoku's largest city, possesses one of Japan's oldest and finest hot springs in Dogo Onsen, a bathhouse of such architectural and historical significance that it inspired the setting of Miyazaki's Spirited Away. Kochi, facing the Pacific, has a wild, salt-sprayed character entirely different from the sheltered Inland Sea coast — its Sunday street markets, katsuobushi-scented air, and unvarnished directness make it Shikoku's most characterful city.
The island's ryokan culture is intimate and unpretentious. Properties here tend smaller, more personal, more rooted in their specific landscape than the grand establishments of Kansai or Hakone. A night at a mountain lodge in the Iya Valley or a seaside inn on the Shimanto River offers something increasingly rare in Japan: genuine solitude, the sound of water, and a meal composed entirely of what the surrounding land and sea provided that morning.

Geography
The Shikoku Mountains run east-west through the island's interior, their highest point Mount Ishizuchi at 1,982 meters — the tallest peak in western Japan. These mountains divide the island into a northern coastal strip facing the Inland Sea and a southern expanse opening onto the Pacific, creating two fundamentally different landscapes. The north is gentle, warm, and relatively developed; the south is rugged, typhoon-swept, and dramatically beautiful.
The Shimanto River in Kochi, often called the last clear stream of Japan, winds through its valley without a single dam, its waters a transparency that allows every stone on the riverbed to be counted. The Niyodo River rivals it in clarity. The Naruto Strait between Tokushima and Awaji Island produces whirlpools of extraordinary power, created by tidal differentials between the Inland Sea and the Pacific. The Iya Valley's double vine bridges — kazurabashi — span a gorge of primeval beauty, while the karst plateau of Shikoku Karst along the Ehime-Kochi border offers alpine meadows and limestone formations at altitude that feel transplanted from another country entirely.
Culture
The Shikoku Henro pilgrimage is the island's defining cultural institution, a practice of walking meditation that has shaped local identity for centuries. The concept of osettai — the spontaneous offering of food, drink, or shelter to passing pilgrims — remains a living tradition, an expression of generosity rooted in the belief that each pilgrim carries something of Kukai's presence. The eighty-eight temples themselves range from grand complexes like Zentsu-ji, Kukai's birthplace, to tiny mountain hermitages accessible only on foot, each marked by the particular devotional character of its setting.
Beyond the pilgrimage, Shikoku's cultural texture includes the Awa Odori of Tokushima — Japan's largest dance festival, held each August, when hundreds of thousands of dancers and spectators fill the streets in a controlled frenzy of bon odori that makes other festivals seem restrained. Ehime's tradition of haiku poetry, centered on Matsuyama, the hometown of Masaoka Shiki, pervades the city — haiku post boxes stand on street corners, and the annual haiku contest draws tens of thousands of submissions. Kochi's yosakoi festival, born in 1954 but now exported across Japan, combines traditional naruko clappers with contemporary choreography in a celebration of communal energy.
Cuisine
Kochi's katsuo no tataki — bonito seared over straw flame until the exterior chars while the interior remains jewel-red and raw — is one of Japan's great single-ingredient dishes, its simplicity a direct expression of the Pacific coast's fishing culture. The straw searing, traditionally done over rice straw, imparts a smoky fragrance that no other method replicates, and the fish is served with sliced garlic, myoga ginger, and a ponzu that cuts the richness with citric precision.
Sanuki udon from Kagawa is a regional obsession elevated to art form — the noodles, made from locally milled wheat and worked by foot to develop their characteristic chew, are served in variations from the austere simplicity of kamatama (tossed with a raw egg and soy) to rich niku udon crowned with sweet-simmered beef. Kagawa's devotion to udon is so complete that the prefecture's density of udon shops exceeds any other food-establishment ratio in Japan. Tokushima contributes sudachi, the small green citrus whose tart, aromatic juice is indispensable across Shikoku's cuisine, and Ehime's mikan tangerines — the Iyokan and Dekopon varieties especially — are among the finest citrus fruits grown anywhere. The Inland Sea side yields tai sea bream, traditionally served whole in the celebratory taimeshi, mixed with rice in preparations that differ between Matsuyama and Uwajima in ways that inspire fierce local partisanship.
