Tona II – the north-eastern part of the Sangihe islands in North Sulawesi
Tona II is located in Tahuna Timur district of Kepulauan Sangihe regency, situated in North Sulawesi province in the northern part of the Republic of Indonesia. The settlement forms part of the Sangihe island group, a chain of islands wedged between the Celebes Sea and the Molucca Sea. The Sangihe islands represent an important geographic line in the Indonesian-Philippine maritime region, defining the eastern edge of the Celebes Sea. The area is of volcanic character, distinguished by active volcanic activity and fertile soils. The island group, which came under Dutch control in 1677, became part of the new nation-state following Indonesia's proclamation of independence in 1945.
General overview
Tona II is a smaller settlement belonging to Tahuna Timur district within the Sangihe island system. The town is located in the northern part of the island group, which operates as an independent regency (Kepulauan Sangihe) in North Sulawesi province. The total area of the Sangihe island group is 813 square kilometers, comprising several dynamic and active volcanic islands. Tahuna city serves as the administrative and economic center of the island group and is home to Naha Airport, the region's only international airport. This region, lacking rail connections, relies instead on maritime transport and air freight.
Due to the limited availability of settlement-level data, reference must be made to the general characteristics of Tahuna Timur district and the entire Kepulauan Sangihe regency. The population of the region stood at 126,133 people for the Sangihe island group as a whole according to the 2010 census, and the area presumably experienced organic growth in the two decades following the turn of the millennium. The island group, located in the south-eastern part of Indonesia, occupies a peripheral or semi-peripheral position within the country, though it holds a distinct role in the geopolitical and economic strategy of the Asia-Pacific region. The local language is Sangir (or Sangihe), an Austronesian language with scattered speakers also found in the Philippines and at the northern tip of Sulawesi.
The archipelago's volcanic origin and associated geomorphology determine the ecological and economic character of the settlement and its immediate region. The Sangihe tectonic plate is one of Indonesia's most active volcanic zones, as reflected by the numerous active volcanoes in the island group. The region's climate is tropical, characterized by alternating rainy and dry seasons, which fundamentally shape agriculture and fishing.
Real estate and investment
Tona II and the Sangihe island group generally are regarded as an underdeveloped but potentially attractive investment zone in the Indonesian real estate market. In the absence of settlement-level concrete data, one must consider the general real estate market dynamics of Kepulauan Sangihe regency and North Sulawesi province. Under Indonesian land ownership regulations, foreign nationals cannot acquire full ownership rights (tanah hak milik) over developed land. Alternatives include building rights (hak guna bangunan – maximum 30 years) or usage rights (hak pakai – maximum 25 years, extendable once). The Indonesian legal regime thus directs foreign investors toward time-limited but long-term sustainable structures.
The peripheral position of the Sangihe island group within Indonesia means that the real estate market is less dynamic than on Java or Bali. However, the region's volcanic soil and tourism potential—particularly regarding fishing, cultural tourism, and ecotourism opportunities—provide grounds for medium and long-term property value appreciation. The island terrain and limited transportation infrastructure function as constraining factors in property valuation. In the decades following the turn of the millennium, the region has experienced meaningful advances in infrastructure development, which similarly enhance real estate market potential. Unknowns—areas that remain incompletely surveyed—mean that the region presents high risk and volatility for investors. Strong community structures, unclear local property rights, and informal regulation are further factors to consider when acquiring property.
Safety and security
The public safety situation in Tona II and the entire Sangihe island group is generally considered stable and secure compared to the Indonesian average, although concrete settlement-level public safety data is not available. North Sulawesi and particularly the Sangihe island group region ranks among Indonesia's safer areas. Religious communities and religious tensions in the region are generally lower than in many other parts of the country, though security challenges increasingly experienced in many parts of the Indonesian archipelago—such as occasional extremist group activity and maritime piracy in exposed areas—merit attention.
The natural hazard exposure of the island area stems from volcanic activity and the annual cyclone season, which does not directly constitute an elevated risk factor regarding criminal behavior, banditry, or political-religious violence. Indonesian public safety presents a mixed national picture: several major cities and tourist centers have stronger enforcement capacities, while isolated, rural, or island communities generally operate with lower financial law enforcement capacity. The social cohesion of the Sangihe island group, strong local institutions, and relatively even development levels, however, result in a more positive public safety situation than in many other parts of the country. Customary law and community norms are strong here, which, alongside formal law enforcement mechanisms, support order mediated through social sanctions.
Tourist attractions
Concrete, verifiable data on settlement-level tourist attractions in Tona II is not available. Nonetheless, the Sangihe island group as a whole, and thus Tona II directly through its association with Tahuna Timur district, possesses numerous natural and cultural attractions. The archipelago's most characteristic landmark is Mount Awu, located on the group's largest island, Sangir Besar (or Sangir Island), at a height of 1,320 meters. This active volcano is one of the region's most prominent volcanic peaks and represents a significant focus for tourism and scientific interest.
All islands of the archipelago (Sangir Besar, Siau, Tagulandang, Biaro, and smaller islands) lie between the Celebes Sea and the Molucca Sea, representing considerable potential for deep-sea fishing, coral fauna, and ocean tourism. Tahuna city, the administrative and economic center of the regency and the most developed settlement with superior infrastructure across the entire Kepulauan Sangihe archipelago. The city is home to Naha Airport, the region's only airport serving international standards and thus the main gateway to the outside world. The city itself possesses cultural and historical institutions (museums, local markets, traditional fishing industry infrastructure) that can generate tourism appeal for anthropological and cultural tourism.
The Sangihe island group itself is the center of Sangir language use, which encompasses a strong cultural identity and linguistic particularities in the region. Observation of indigenous and traditional coastal lifestyles, as well as study of handcrafted fishing net production (preserved based on the region's past), can hold significant ethnographic interest. Beyond active volcanic geology, the island group's coastal zones bordered by coral reefs provide suitable conditions for diving, scientific observation of coral flora and fauna.
Summary
Tona II is located in Tahuna Timur district of Kepulauan Sangihe regency, forming part of the volcanic island world of Indonesia's north-eastern archipelago in North Sulawesi province. The settlement itself lacks studied observations published on tourism or economic grounds, yet the Sangihe island group as a whole constitutes a volcanic, biologically rich, culturally strong, and geopolitically strategically important region. Real estate market opportunities are limited, infrastructure is under development, public safety is generally acceptable, and tourism potential lies primarily in the area's volcanic, marine, and ethnic characteristics. In such island settlements occupying peripheral positions within Indonesia, authenticity, a non-mass tourism character, and strong local communities form the primary attractions for interested visitors and investors.
