For residents of Japan’s western island of Shikoku, flying internationally to South Korea is about to become cheaper than taking the bullet train to their own capital, with one-way fares under 200,000 Korean won directly challenging Tokyo’s domestic travel prices. When Aero K launches regular three-times-weekly scheduled flights between Cheongju and Matsuyama on 2 January 2027—following charter operations that logged passenger occupancy approaching 90%—it will cement an unprecedented regional corridor that bypasses Seoul, Tokyo, and Osaka entirely. For cultural wanderers seeking genuine immersion away from overcrowded tourist capitals, this regional gateway opens a quiet portal linking the historical temples of central South Korea directly with the ancient bathhouses, feudal stone ramparts, and island-hopping cycling routes of Ehime Prefecture.

A Subsidized Sky-Bridge Links Central Korea to Shikoku

The formal announcement made by the Ehime Prefectural Government on 30 September 2026 marks a decisive shift in how regional Asian destinations build bilateral tourism. Rather than waiting for travelers to trickle in through major hub connections like Tokyo Haneda or Seoul Incheon, regional authorities partnered directly with South Korean carrier Aero K Airlines. Scheduled operations will commence on Saturday, 2 January 2027, maintaining a consistent rhythm of three flights per week on Tuesdays, Thursdays, and Saturdays.

The transition from charter to scheduled operations is underpinned by solid consumer demand. During preliminary charter trial runs, Aero K recorded passenger load factors approaching 90%, proving that South Korean travelers are increasingly drawn to second-tier Japanese cities that offer unhurried, authentic local culture. Operating out of Cheongju International Airport, the service provides an accessible international departure point for more than 5.5 million residents living in the Chungcheong region, allowing travelers to skip the two-hour overland trek to Incheon.

What makes this initiative particularly noteworthy is the aggressive suite of bilateral incentives engineered by prefectural authorities. To encourage arriving Korean travelers to explore beyond typical airport transfer zones, Ehime Prefecture established a program providing free attraction passes at the Matsuyama Airport information desk for passengers arriving on direct international flights. These passes grant complimentary admission to Matsuyama Castle, the historic Dogo Onsen complex, and the Towel Museum in Imabari. In parallel, Matsuyama Airport and municipal transit authorities have installed comprehensive Korean-language wayfinding signs, transit brochures, and attraction maps.

Simultaneously, Ehime has taken the unusual step of subsidizing outbound international travel for its own citizens to foster two-way route sustainability. Between April 2025 and March 2026, the prefecture provided financial assistance equivalent to approximately KRW 80,000 for residents aged 13 to 25 acquiring or renewing passports. For the financial year spanning April 2026 to March 2027, assistance equivalent to approximately KRW 100,000 is being provided to eligible members of a regional educators' and staff mutual-aid association, with further educational travel support proposed for university and vocational students. By lowering passport barriers and offering promotional fares projected below KRW 200,000 one-way, flying across the Korea Strait is being positioned as a direct, affordable alternative to domestic domestic rail trips to Tokyo.

What Makes Matsuyama and Ehime Prefecture Different

Matsuyama is a destination whose cultural identity is rooted in water, stone, and literature. Situated on the western coast of Shikoku facing the sheltered Seto Inland Sea, the city escaped the widespread destruction of wartime bombing that flattened many Honshu capitals, leaving its historical fabric remarkably intact.

The crown jewel of Matsuyama is Dogo Onsen, one of Japan's oldest documented hot springs with a recorded history spanning three millennia. At its heart stands the Dogo Onsen Honkan, a multi-story wooden bathhouse erected in 1894 whose intricate timber gables, shoji screens, and rooftop watchtower inspired the enchanted bathhouse depicted in Studio Ghibli’s animated classic Spirited Away. Bathing here is a timeless ritual: soaking in smooth, alkaline spring waters before relaxing in private tatami rooms while sipping roasted green tea served with sweet botchan dango (three-colored rice dumplings).

Overlooking the city from the forested summit of Mount Katsuyama sits Matsuyama Castle, constructed between 1602 and 1628. It is one of only twelve surviving original castle keeps (tenshu) in Japan that predates the Edo period. Visitors can ascend the mountain via a vintage chairlift or walking trail to explore complex defensive gate systems, hidden arrow slits, and wooden ramparts that offer panoramic vistas sweeping across the urban grid toward the Seto Inland Sea.

Connecting these heritage landmarks is Matsuyama’s beloved streetcar network. Trams have operated through the city center since the Meiji era, including the Botchan Train—a diesel-powered replica of the historic steam locomotive immortalized in Natsume Soseki’s famous 1906 novel Botchan. Beyond the city limits, Ehime Prefecture unfolds into preserved merchant towns like Uchiko, where the Yokaichi and Gokoku preservation district showcases 200-year-old plaster-and-timber merchant houses that once produced traditional sumac wax, alongside the historic Uchiko-za kabuki theater. Further north, Imabari anchors the Shimanami Kaido, a world-renowned 70-kilometer cycling expressway that links Shikoku to Honshu across six scenic islands in the Seto Inland Sea.

This rich blend of preserved heritage aligns with cultural preservation benchmarks championed by UNESCO across East Asia, providing cultural travelers with an intimate alternative to Japan's Golden Route.

Visitor Insider Tips

  • Timing Your Dogo Onsen Visit: Dogo Onsen Honkan is immensely popular, and entry tickets operate on timed reservation slots during peak hours. Arrive by 8:30 a.m. to secure a morning bathing slot before weekend crowds arrive from Hiroshima and Osaka. For a serene open-air soak, visit the nearby Dogo Onsen Asuka-no-Yu annexe in the late evening, where the modern bath halls showcase traditional Ehime craftsmanship, including gilded Washi paper and local Tobe porcelain tiles.
  • Maximizing the Three-Day Flight Rhythm: Because Aero K operates strictly on Tuesdays, Thursdays, and Saturdays, plan your itinerary in multi-day blocks. A Tuesday-to-Saturday trip provides four nights—ideal for spending two nights exploring Matsuyama’s castles and onsen, followed by two nights cycling along the Shimanami Kaido or staying in a traditional merchant posada in Uchiko.
  • Regional Gastronomy Beyond Sushi: Ehime’s signature specialty is Taimeshi (sea bream rice). In Matsuyama, try the Uwajima-style Taimeshi, where raw fillets of wild sea bream are marinated in a mixture of raw egg, soy sauce, mirin, and sesame seeds before being poured over steaming rice. In the evening, visit the casual izakayas along Okaido arcade for Jakoten—minced small white fish ground into patties with bones and skin, deep-fried until chewy, and served sizzling with grated daikon and soy sauce.
  • Renting Bikes for the Shimanami Kaido: If you plan to cycle the Shimanami Kaido from Imabari, book rental cross-bikes or e-bikes online at least two weeks in advance during spring and autumn. You can pick up a bicycle at Sunrise Itoyama at the foot of the Kurushima Kaikyo Bridge and drop it off at designated terminals across the islands or in Onomichi on Honshu.
  • Navigating Matsuyama Airport Transit: Matsuyama Airport sits just six kilometers west of the city center. Avoid waiting in taxi lines; board the dedicated Iyotetsu airport limousine bus directly outside arrivals. The bus reaches JR Matsuyama Station in 15 minutes and Dogo Onsen in 40 minutes, with fare payments easily handled via standard Japanese IC transport cards or cash.

Cultural and Environmental Context

The opening of direct regional routes like Cheongju–Matsuyama represents a healthier, more sustainable future for Asian tourism, aligning with regional dispersion strategies promoted by the Japan National Tourism Organization and the Korea Tourism Organization. For years, Japan has struggled with severe overtourism concentrated in Tokyo, Kyoto, and Mount Fuji. By directing international travelers into provincial regions like Shikoku, visitor spending flows directly into independent ryokans, family-owned noodle shops, and traditional craft studios, revitalizing aging rural communities without overwhelming municipal resources.

Environmental preservation is especially critical across the Seto Inland Sea, Japan's first designated national park. The delicate marine archipelago traversed by the Shimanami Kaido relies on low-impact, human-powered eco-tourism. Cycling and walking along designated coastal paths generate minimal carbon emissions while encouraging travelers to engage respectfully with small island communities like Oshima and Ikuchijima.

Furthermore, authentic cultural exchange between South Korea and regional Japan helps foster grassroots international understanding. Historically, Shikoku was isolated from international commerce; today, Korean-language hospitality at Dogo Onsen and reciprocal travel grants for Japanese students create human connections that transcend national politics, demonstrating that thoughtful aviation partnerships can bridge regional communities while preserving their unique cultural rhythm.
