Shodoshima Island: Showa-Era Schoolhouses, Ancient Rice Terraces & 400-Year-Old Soy Sauce

Shodoshima is where time forgot to move forward. On this island in the Seto Inland Sea, wooden schoolhouses from the 1930s still stand overlooking the ocean, farmers tend 700-year-old rice terraces by hand, and craftsmen brew soy sauce in cedar barrels using techniques unchanged for four centuries. For travelers seeking authentic Japan beyond the tourist trail, Shodoshima offers something increasingly rare: a genuine window into the country’s soul.

Located just 35 minutes by high-speed ferry from Takamatsu in Kagawa Prefecture, this 153-square-kilometer island remains largely untouched by mass tourism. While Shodoshima is known as the birthplace of Japanese olive cultivation—complete with a picturesque Olive Park featuring a Greek-style windmill and Mediterranean atmosphere—the island’s true treasures lie elsewhere. They’re found in the quiet Showa-era landscapes, the patient rhythm of traditional agriculture, and the master craftsmen who have refused to abandon their ancestral ways.

This guide focuses on what makes Shodoshima truly special: the nostalgic beauty of pre-war Japan and the living traditions that have survived into the modern age.

Twenty-Four Eyes Movie Village: Step into 1930s Rural Japan

The Twenty-Four Eyes Movie Village (Nijushi no Hitomi Eigamura) is the single most evocative destination on Shodoshima—a place where the Showa era lives and breathes. Built as a filming location for the 1987 adaptation of Sakae Tsuboi’s beloved novel, this meticulously recreated village transports visitors to rural Japan of the 1920s through 1940s. The story follows a young teacher and her twelve students through the turbulent years of war and its aftermath, and the village preserves that vanished world with remarkable authenticity.

What sets this place apart from typical theme parks is its genuineness. These aren’t plastic replicas but actual movie sets built with salvaged materials from historical buildings. The weathered wood, the faded signs, the worn stone paths—everything carries the patina of real age and use.

The Cape Schoolhouse

The village’s emotional center is the Cape Schoolhouse (Misaki no Bunkyojo), a small wooden school perched on a hill with sweeping views of the Seto Inland Sea. Step inside and you’ll find rows of old wooden desks and chairs arranged as if students just left for recess. The blackboard displays chalked lessons in pre-war script. On the desktops sit Showa-era textbooks, slate writing boards, and abacuses.

The classroom windows frame the same calm waters that generations of real students once gazed upon during lessons. Floorboards creak underfoot. Bare light bulbs hang from the ceiling. Behind the classroom, the teacher’s living quarters reveal the modest reality of rural education: a tiny kitchen, a charcoal brazier for heat, a tatami room for sleeping. This simplicity speaks volumes about an era when dedication mattered more than comfort.

Showa-Era Shopping Street

The recreated “Taura” shopping street captures the commercial heart of a small Japanese town from the early to mid-Showa period. A pharmacy, general store, photo studio, post office, and dagashiya (penny candy store) line the narrow street, each filled with period-appropriate merchandise and tools.

The dagashiya deserves special attention. Glass cases overflow with nostalgic Japanese candies—Baby Star Ramen snacks, kinako sticks, dried squid strips. For international visitors, this is a window into childhood entertainment before digital screens existed. Tin toys, menko cards, marbles, and kamishibai (paper theater) sets show how children once played.

The photo studio displays large bellows cameras and sepia family portraits from an era when photography was a rare and treasured event—a striking contrast to our age of disposable smartphone images.

Kinema no An Museum

This museum houses exhibits on author Sakae Tsuboi, the filmmaking process, and most valuably, original artifacts from pre-war schools: actual textbooks, students’ essays, and picture diaries. The collection includes wartime ration books, photographs of soldiers departing for battle, and militaristic educational materials. Since “Twenty-Four Eyes” tells of bonds torn apart by war, these documents transform the story from fiction into felt history.

The Original Cape Schoolhouse

Ten minutes by car from the movie village stands the actual schoolhouse that inspired the story—a genuine wooden building constructed in 1902 and used until 1971, now registered as a Tangible Cultural Property of Japan.

Unlike the movie set, this building shows its century-plus of age honestly. Wood weathered through countless seasons. Paint faded by decades of sun. The entire structure radiates the gravity of lived history. Inside, original desks and teaching materials remain. What makes this place special is what it lacks: no crowds, no gift shops, just sea breeze and wave sounds, leaving space to imagine the children who once filled these rooms before war scattered them across the world.

Nakayama Senmaida: 700-Year-Old Rice Terraces Still Farmed by Hand

Nakayama Senmaida represents Japanese agriculture at its most timeless—approximately 800 rice paddies cascading down a mountainside in patterns established during the Kamakura period over 700 years ago. Designated as one of Japan’s Top 100 Rice Terraces, this is not a museum or reconstruction. These are working fields where local farmers still cultivate rice exactly as their ancestors did, because the terrain allows no other way.

Seven Centuries of Agricultural Heritage

The terraces date to the 13th century, when farmers on this island of scarce flat land carved steps into steep slopes and stacked stones to create paddies. Individual plots are remarkably small—the tiniest measure just a few square meters—making modern machinery impossible. Every stage of cultivation, from planting to weeding to harvest, must be done by hand.

The stone walls supporting these terraces represent generations of accumulated skill. Built using the traditional “nozurazumi” technique—stones fitted together without mortar—they incorporate drainage channels that prevent collapse during heavy rains. This engineering wisdom has proven itself across seven centuries of typhoons and downpours.

A Living Cultural Heritage

Rural depopulation threatens rice terraces across Japan, and Nakayama Senmaida has shrunk from over 1,000 paddies to roughly 800. But the Nakayama Senmaida Preservation Society works to maintain both landscape and tradition, welcoming volunteers during planting and harvest seasons.

Participants plant seedlings by hand and cut rice with sickles—not as tourist entertainment but as genuine cultural preservation. Rice grown here sells as “Senmaida Rice,” cultivated with minimal chemicals and irrigated by pure mountain springs. The yield is small, the labor immense, but the taste is said to be exceptional.

The Four Seasons of Senmaida

The terraces transform dramatically through the year:

Spring (May): Flooded paddies become mirrors reflecting sky and mountains. At sunset, the water turns gold. Rice planting from mid to late May brings the community together for hand-transplanting seedlings.

Summer (June-August): Brilliant green waves of growing rice cascade down the slopes. Farmers work constantly at weeding and water management.

Autumn (September-October): The most photogenic season. Golden rice stalks bend heavy with grain. After harvest, look for “inekigake”—traditional wooden frames where rice bundles hang to dry in the sun.

Winter (November-February): Quiet rest. Some farmers flood their paddies to regenerate soil. Occasional snow creates monochrome landscapes. Time for repairing stone walls and preparing for the next cycle.

Nakayama Rural Kabuki

The Nakayama district preserves another tradition: agricultural kabuki performed every October during harvest festival on a genuine 1902 stage designated as an Important Tangible Folk Cultural Property. This stage has a revolving platform, hanamichi runway, and trap rooms—full professional apparatus in a farming village. Local residents perform plays passed down through generations, demonstrating that traditional performing arts once belonged to everyday community life, not just elite urban theaters.

Hishio no Sato: 400 Years of Soy Sauce Tradition in Black-Walled Breweries

Shodoshima has produced soy sauce for over 400 years, and the Hishio no Sato district preserves rows of traditional breweries where craftsmen still work exactly as their Edo-period predecessors did. Walking these streets of dark wooden buildings, the aroma of fermentation drifting through the air, you’re experiencing Japanese food culture in its most authentic form.

Four Centuries of Brewing Heritage

Soy sauce production began here in the early 1600s. The island’s mild climate, excellent water, and location on maritime trade routes made it ideal for brewing. At the industry’s peak during the Meiji and Taisho eras, over 400 breweries operated on Shodoshima. Today roughly 20 remain—yet the island still leads Japan in traditional wooden-barrel-fermented soy sauce production.

While major manufacturers have shifted to stainless steel and accelerated processes, Shodoshima’s craftsmen stubbornly maintain the old ways. Their soy sauce takes years, not months. And it tastes different because of it.

The Art of Wooden Barrel Brewing

Many breweries still use massive cedar barrels in continuous use since the Edo period—giants standing over two meters tall, each holding approximately 6,000 liters of moromi (soy sauce mash). Inside the wood live colonies of yeast and lactobacillus cultivated over decades or centuries, creating flavors unique to each brewery. Same ingredients, same methods, different barrels—different taste.

The barrel-making craft itself faces extinction. Only a handful of artisans in Japan can still construct these vessels, requiring months of work with cedar aged over 100 years. Shodoshima’s breweries treat their existing barrels as irreplaceable heirlooms.

Yamaroku Soy Sauce

Operating for over 150 years across five generations, Yamaroku stands out even among traditional producers. Current owner Yasuo Yamamoto not only brews in wooden barrels but learned the endangered art of barrel-making himself, constructing new barrels in 2012—an extraordinarily rare achievement in modern Japan.

Factory tours (reservation required) allow visitors inside the dim warehouses to stand among towering barrels where moromi ferments for a minimum of two years—four years or more for premium products. The complex aroma—sweet, sour, and deeply savory—cannot be replicated by industrial processes. The brewmaster evaluates progress by scent, appearance, and taste alone. No instruments. Just knowledge accumulated over lifetimes.

Yamaroku’s signature “Tsuru Bishio” uses finished soy sauce instead of salt water for a second fermentation, creating exceptional depth. This luxury product appears in high-end restaurants worldwide.

Marukin Soy Sauce Memorial Hall

This Taisho-era factory operated until 1987 and is now preserved as a museum registered as a Tangible Cultural Property. Massive wooden barrels—dozens of them, nearly three meters tall—still bear dark staining from years of use. Exhibits guide visitors through every production stage using original equipment: great cauldrons for steaming soybeans, koji rooms, presses, bottling machinery. The hand-operated tools from before electrification reveal how physically demanding the work once was.

Don’t miss the “soy sauce soft cream” at the gift shop—vanilla ice cream enriched with soy sauce. The combination of sweet, salty, and umami surprises skeptics into converts.

Kankakei Gorge: Dramatic Valley Views and Autumn Colors

Kankakei ranks among Japan’s three most beautiful valleys—a spectacular landscape of strange rock formations and deep ravines created by volcanic activity 13 million years ago. The Kankakei Ropeway carries visitors from Koun Station to the summit in about five minutes, offering aerial views of the gorge’s pillars and the Seto Inland Sea beyond.

Multiple observation platforms at the top reveal different perspectives on the valley. The scenic points called “Omote Junikkei” (Twelve Front Views) and “Ura Hakkei” (Eight Rear Views) showcase the variety of rock formations. On clear days, you can see the Seto Ohashi Bridge connecting Shikoku to Honshu.

Best time to visit: Autumn foliage from mid to late November draws crowds—visit early morning or on weekdays. Spring and summer offer quieter experiences with lush greenery.

Angel Road: The Sandbar That Appears Twice Daily

Angel Road is a 500-meter sandbar connecting Shodoshima to the small offshore island of Nakayojima—but only during low tide, twice each day. Local legend promises that couples who walk hand-in-hand across this path will have their wishes granted, earning it certification as a “Lover’s Sanctuary.”

Planning your visit: The sandbar is walkable for approximately two hours before and after low tide. Check tide tables on the Shodoshima Tourism Association website before visiting. The “Yakusoku no Oka Observatory” (Promise Hill) overlooks the entire sandbar—sunset views are particularly magical when golden light paints the sand and sea.

Getting to Shodoshima

Best Time to Visit

Shodoshima enjoys mild Seto Inland Sea climate year-round:

Spring (March-May): Pleasant temperatures. Rice planting at Nakayama Senmaida (May) creates mirror-like flooded paddies.

Summer (June-August): Hot and humid. Beaches near Angel Road attract swimmers. Take precautions against heatstroke.

Autumn (September-November): Peak season. Golden rice terraces (late September-early October), Kankakei autumn foliage (mid-late November), comfortable weather.

Winter (December-February): Quietest season. Crisp air offers exceptional visibility. Some ferry services reduced—check schedules.
