[Matsuyama, Japan] — A strategic expansion of air connectivity between Japan and South Korea is set to begin on January 2, 2027, as Aero K introduces a scheduled service linking Matsuyama Airport and Cheongju International Airport. This new operation will provide Ehime Prefecture with a third direct gateway to South Korea, significantly enhancing the accessibility of the Shikoku region for international visitors and providing local residents with expanded travel options.

The decision to launch the route follows a series of successful trial operations and high-demand charter programs. By establishing this link, Aero K aims to tap into the central South Korean market, offering a streamlined alternative to the traditional hubs of Seoul and Busan.

Aero K Flight Schedule and Aircraft Specifications

According to official confirmations from Ehime Prefecture released on September 30, 2026, the airline has finalized internal plans to operate the Matsuyama–Cheongju service three times per week. The flights are scheduled to depart on Tuesdays, Thursdays, and Saturdays.

To service this route, Aero K will deploy the Airbus A320, a narrow-body aircraft well-suited for the short-haul international jump. While the schedule is currently set, officials have noted that the final launch remains subject to formal approval and coordination with Japan’s Ministry of Land, Infrastructure, Transport and Tourism, as well as various airport authorities.

Matsuyama Airport Reaches Record International Capacity

The introduction of the Cheongju service marks a significant milestone for Matsuyama Airport, representing its first new international connection in approximately three years since the Busan route was established.

Once the Aero K flights commence, the airport's total international network will expand to a record 27 weekly flights. These services will connect Matsuyama to four key international destinations:

  • Seoul
  • Busan
  • Cheongju
  • Taipei

With three distinct links to South Korea, Ehime Prefecture will hold the highest number of Korean flight routes among all airports located within the Chugoku and Shikoku regions. This strategic positioning is intended to diversify the origin of inbound tourists, reducing the reliance on the primary Seoul and Busan markets.

Proven Demand via Sold-Out Charter Programs

The transition to a scheduled service is backed by empirical data from 2026. In June, Aero K executed a targeted inbound charter program from Cheongju to Matsuyama. These flights operated on June 2, 4, 6, and 9, totaling four round trips. Every seat on these flights was sold, signaling a strong appetite for direct access to Ehime.

Industry reports indicate that South Korean travel agencies found several factors highly attractive to consumers:

  • The minimal transit time between Matsuyama Airport and the city center.
  • The high density of primary tourist attractions within the city.
  • The viability of themed travel, specifically golf tourism.
  • The ease of accessing eastern and southern Ehime for broader regional exploration.

To further validate the market, Aero K implemented a secondary trial phase from October 14 to October 25, 2026. This period saw six round trips operating on Wednesdays, Fridays, and Sundays. Unlike the June charters, these flights were open to both inbound and outbound passengers, allowing the airline to confirm that demand existed for Japanese travelers heading to South Korea as well.

Strategic Importance of Cheongju as a Hub

The choice of Cheongju International Airport is a calculated move by Aero K. Located in the heart of South Korea, Cheongju serves a commercial catchment area with a population of approximately 5.5 million people.

By basing the route in central South Korea, Aero K avoids direct head-to-head competition with larger carriers operating out of the saturated Seoul and Busan hubs. For passengers in the central region, this removes the need for lengthy domestic surface travel to reach a major international gateway. As Cheongju is the primary base for Aero K, the airline is leveraging its existing infrastructure to make Matsuyama its first destination on the island of Shikoku.

Flight Duration and Regional Accessibility

The estimated flight time between Matsuyama and Cheongju is approximately 90 minutes. This short duration transforms the nature of the trip, moving it from a "major holiday" category into the realm of "short-break" travel.

For residents of Shikoku, the 90-minute flight makes South Korea a viable option for weekend getaways. Conversely, for Korean tourists, the efficiency of the flight—combined with the short commute from the airport to the city—makes Matsuyama a highly competitive destination compared to other Japanese cities that require long train or bus transfers from the airport.

Driving Tourism Growth in Ehime Prefecture

The route is designed to funnel visitors toward the cultural and natural assets of Ehime. Matsuyama is already a primary draw due to the historic Dogo Onsen and the elevated Matsuyama Castle, which offers panoramic views of the region.

However, local authorities are using this new connectivity to push tourism deeper into the prefecture. The goal is to encourage visitors to explore:

  • Eastern Ehime: Known for its industrial history, unique island landscapes, and local culinary specialties.
  • Southern Ehime: Characterized by scenic coastal vistas and traditional small-town charm.

The success of the June charter packages, which explicitly included itineraries beyond the city limits, suggests that Korean travelers are interested in a comprehensive experience of the prefecture rather than a simple city break.

South Korean Market Impact on Local Economy

The reliance on the South Korean market is justified by recent growth statistics. According to data cited by the prefecture, foreign overnight stays in the region have surged, with a year-on-year increase of approximately 28.6% for the first half of 2026.

The strong performance of existing routes to Seoul and Busan provided the foundation for this expansion. By adding Cheongju, Ehime is effectively widening its net to capture a broader demographic of South Korean travelers, ensuring a more stable and diverse stream of international tourism revenue.

Why This Matters

For the traveler, this development eliminates the "hub-and-spoke" fatigue. Traditionally, visiting Shikoku from South Korea required navigating the massive transit hubs of Osaka or Tokyo, adding hours of travel time and significant cost. The direct Cheongju link democratizes access to the region.

From a logistical standpoint, this represents a shift in how regional Japanese airports are competing. Rather than fighting for the same passengers at Incheon (Seoul), Matsuyama is creating its own niche by partnering with a regional carrier (Aero K) and a regional hub (Cheongju). This "regional-to-regional" model is likely to become a blueprint for other secondary cities in Japan looking to increase their international footprint without relying on the congestion of major metropolitan airports.
