Shimojishima is not a traditional city founded by decree, but an island whose history of settlement is inextricably linked to the neighboring island of Irabu and the Miyako archipelago. The first settlements here formed naturally during the era when these lands were within the sphere of influence of the Ryukyu Kingdom.
Historically, Shimojishima was seen as an extension of Irabu, from which it is separated only by a narrow strait. In ancient chronicles, this area is mentioned as a home for fishermen and farmers who lived in harmony with the sea and followed local chieftains (aji) before unification under Ryukyu rule.
Key Factors of Development
The development of the territory was determined by its unique geographical and natural conditions:
Geography: The island is of coral origin and is surrounded by rich reefs. The narrow strait between Shimojishima and Irabu served as a natural harbor, protecting boats from typhoons.
Isolation and Connections: For a long time, the island remained relatively isolated, which helped preserve its traditional way of life. Connections to the outside world were maintained through sea routes linking the Miyako islands with Okinawa and mainland Asia.
Water Resources: The presence of unique natural bodies of water, such as the Tori-ike Ponds, played an important role not only in water supply but also in shaping local mythology.
Early Cultural and Economic Features
The economy and culture of the early period were based on natural resources and spiritual traditions:
Traditional Trades: The basis of survival was fishing in coastal waters and growing sugarcane on arable plots of land.
Spiritual Life: Like on other Ryukyu islands, animistic beliefs were strong here. Local residents revered sacred groves (utaki) and natural sites, believing in their connection to deities of the sea and fertility.
Architecture: Early dwellings were built with frequent typhoons in mind, using local materials—coral limestone for walls and vegetation for roofs.
Timeline
The Path to Modernity: Important Milestones
The modern history of Shimojishima is a chronicle of a quiet corner of the archipelago transforming into a major transport and tourism hub. Key events in recent decades have fundamentally changed the island's rhythm of life, opening it up to travelers from around the world.
1979: The Era of Aviation. Shimojishima Airport was opened. The project's uniqueness lay in the fact that it was not originally created for mass tourism, but as Japan's only base for training civil aviation pilots. Thanks to its 3,000-meter runway, pilots from major airlines practiced maneuvers here using wide-body aircraft.
2015: The Grand Connection. The opening of the Irabu Ohashi Bridge was a turning point for the region. This engineering masterpiece, 3,540 meters long, connected neighboring Irabu Island (and thus Shimojishima) with the main island of Miyako. Before this, the islands were only accessible by ferry; now, they became easily reachable for cars and tour buses.
2019: A New Tourism Hub. The opening of a new passenger terminal at the airport marked the beginning of a new era. The airport began receiving regular domestic and international flights, including low-cost carriers. The terminal itself, designed in the style of a tropical resort with abundant wood and greenery, instantly became a signature landmark of the island.
Today, Shimojishima is known for its harmonious blend of technology and nature. The famous 17END (the northern end of the runway), where planes land over turquoise waters, has become a symbol of the island's modern history, attracting photographers and romantics alike.
Milestones
Administrative and Social Milestones
The history of Shimojishima is more than just the construction of an airport and bridges. It is a journey of administrative transformation and efforts to preserve a unique ecosystem, which turned a secluded island into part of the modern city of Miyakojima.
1945–1972: The Period of US Administration. Following 1945, the Ryukyu Islands, including Shimojishima, came under US jurisdiction. During these decades, the island lived separately from Japan's main economic system. This era was characterized by the preservation of the traditional way of life and a lack of heavy industry, which allowed the coral landscapes to remain in virtually pristine condition.
1972: Reversion to Japan. The reintegration of Okinawa sparked large-scale modernization. For the residents of Shimojishima and neighboring Irabu, this meant the extension of Japanese social benefits and the beginning of government investment in basic infrastructure: water supply systems, electrification, and coastal reinforcement.
2005: Creation of Miyakojima City. During the "Great Heisei Merger," the town of Irabu (which administratively included Shimojishima) was merged with other municipalities in the archipelago. The island became part of the unified city of Miyakojima. This event centralized management and simplified budget allocation for tourism development and nature conservation.
2006: Recognition of Natural Value. The famous Tori-ike Ponds on the island's west coast were designated as a National Natural Monument and a Place of Scenic Beauty in Japan. This event officially secured Shimojishima's status as an important ecological site, shifting the development focus from purely utilitarian use to ecotourism.
Architecture
Urban Planning and Architectural Identity
Unlike classic cities with historical centers, Shimojishima is a unique example of a territory where urban planning is entirely centered around one function: aviation. The island's landscape is shaped not by residential blocks, but by large-scale transport infrastructure harmoniously integrated into the tropical environment.
You won't find styles like Gothic or Baroque here. The island's architectural history is divided into periods of utilitarian development and modern resort-style urbanism.
Architectural Eras and Styles
The island's development can be divided into three key stages, each leaving its mark on the landscape:
Traditional Way of Life (until the 1970s): Ryukyuan Vernacular Architecture. The few old buildings in the region reflect features characteristic of the Miyako archipelago. These are low, single-story structures designed to withstand typhoons.
Features: Use of coral limestone for protective walls (hinpun) and red tiles secured with plaster.
Infrastructure Era (1979 – late 20th century): Industrial Functionalism. The construction of the training airport brought concrete and steel to the island. Buildings from this period (hangars, control towers, pilot dormitories) are characterized by strict geometry and a lack of decoration.
Features: Priority of function over form, massive structures capable of withstanding storm winds, and minimalist design.
Modern Times (from 2019): Tropical Modernism and Eco-style. With the opening of the passenger terminal, the island's architecture shifted toward aesthetics and comfort. Modern facilities strive to blur the line between indoors and nature.
Features: Use of natural wood (CLT technology), panoramic glazing, open spaces, natural ventilation, and the integration of greenery into interiors.
Iconic Structures
The appearance of Shimojishima is defined by two main sites that symbolize the transition from technical utility to tourist appeal:
Shimojishima Airport Terminal. A striking example of modern resort architecture. The building resembles a luxury villa rather than a terminal. The roof with wide overhangs provides shade from the sun, while the interiors are adorned with pools and tropical plants, creating a "garden airport" atmosphere.
The Runway and 17END. A grand engineering feat that extends directly into the turquoise sea. The pier for navigation lights at the northern tip of the runway has become more than just a technical element; it is the island's most recognizable visual landmark, creating a stunning contrast with the natural lagoon.
