Foundation and First Mentions
The history of the settlement of Okinoerabu is rooted in the prehistoric era; however, the island begins to appear in chronicles as a significant administrative and cultural unit during the Middle Ages. Unlike mainland cities, development here progressed through the unification of scattered communities:
- Gusuku Period: The active formation of local communities began in the 11th–12th centuries. During this time, the island was ruled by local chieftains called "Aji," who built fortified residences.
- Integration into Ryukyu: The first documented mentions are often associated with the expansion of the Ryukyu Kingdom's influence. In the 14th century, the island became part of the northern Hokuzan principality, which marked the starting point of its political establishment.
Key Factors of Formation
The formation of settlements and the way of life on Okinoerabu were dictated by its unique geology and location within the Amami archipelago:
- Geography and Geology: The island is an uplifted coral atoll. The presence of fertile soils (terra rossa), rich in minerals, allowed for the development of agriculture despite the scarcity of rivers and the necessity to use underground water from karst caves.
- Strategic Location: Situated between the main islands of Japan and Okinawa, Okinoerabu served as a vital link in maritime trade and cultural exchange, acting as a transit point for vessels.
- Political Influence: The transfer of control from the Ryukyu Kingdom to the Japanese Satsuma Domain in the early 17th century (1609) definitively cemented the island's role as an important agrarian centre specialising in sugar production.
Early Cultural and Economic Features
The economy and culture of the early period developed under conditions of isolation and close interaction with nature:
- Agrarian Economy: Unlike many neighbouring islands where fishing dominated, the residents of Okinoerabu historically focused on agriculture, cultivating root crops and sugar cane.
- Stone Architecture: The abundance of coral limestone facilitated the development of unique building skills. Locals erected sturdy stone walls for protection against typhoons.
- Spiritual Culture: Early beliefs were closely tied to the reverence of nature and ancestors (animism), whilst cultural traditions, including music and dance, were formed under the strong influence of Ryukyu aesthetics.
