List of islands of Indonesia in the context of "Wallacea"

Honshu (Japanese: 本州, Hepburn: Honshū; pronounced [hoꜜɰ̃.ɕɯː] ; lit. 'main province'), historically known as Akitsushima (秋津島; lit. 'dragonfly island'), is the largest of Japan's four main islands. It lies between the Pacific Ocean (east) and the Sea of Japan (west). It is the seventh-largest island in the world, and the second-most populous after the Indonesian island of Java.

Honshu had a population of 104 million as of 2017, constituting 81.3% of the entire population of Japan, and mostly concentrated in the coastal areas and plains. Approximately 30% of the total population resides in the Greater Tokyo Area on the Kantō Plain. As the historical center of Japanese cultural and political power, the island includes several past Japanese capitals, including Kyoto, Nara, and Kamakura. Much of the island's southern shore forms part of the Taiheiyō Belt, a megalopolis that spans several of the Japanese islands. Honshu also contains Japan's highest mountain, Mount Fuji, and its largest lake, Lake Biwa.

Indonesia, officially the Republic of Indonesia, is a country in Southeast Asia and Oceania, between the Indian and Pacific oceans. Comprising over 17,000 islands, including Sumatra, Java, Sulawesi, and parts of Borneo and New Guinea, Indonesia is the world's largest archipelagic state and the 14th-largest country by area, at 1,904,569 square kilometres (735,358 square miles). With over 280 million people, Indonesia is the world's fourth-most-populous country and the most populous Muslim-majority country. Java, the world's most populous island, is home to more than half of the country's population.

Indonesia operates as a presidential republic with an elected legislature and consists of 38 provinces, nine of which have special autonomous status. Jakarta, the largest city, is the world's second-most-populous urban area. Indonesia shares land borders with Papua New Guinea, Timor-Leste, and East Malaysia, as well as maritime borders with Singapore, Peninsular Malaysia, Vietnam, Thailand, the Philippines, Australia, Palau, and India. Despite its large population and densely populated regions, Indonesia has vast areas of wilderness that support one of the world's highest levels of biodiversity.

Madura is an Indonesian island off the northeastern coast of Java. The island has an area of about 4,471.05 square kilometres (1,726.28 sq mi), but administratively Madura comprises an area of around 5,408.45 square kilometres (2,088.21 sq mi) due to the inclusion of various smaller islands to the east, southeast and north that are part of Madura's easternmost Sumenep Regency. Madura is part of the province of East Java. It is separated from Java by the narrow Madura Strait. The administered area had a density of 773 people per km (2,003 per sq. mile) in mid-2024, while the main island had a somewhat higher figure of 862.3 per km (2,233 per sq. mile).

The Kangean Islands, also known as the Kangean Archipelago (Kangean: Kapoloan Kangayan) are the group of islands within the Lesser Sunda Islands complex of Indonesian Archipelago located in the northern Bali Sea. It comprises a total of 118 islands (27 inhabited islands), with the Kangean Island as the main and biggest island in the region.

Tyto is a genus of owls in the family Tytonidae. Depending on the species and the locality, common names include barn owl, common barn owl, grass owl, sooty owl, masked owl, field owl or simply owl. It is the most widely distributed genus of owls in the world and one of the most widespread of all genera of birds, living almost everywhere except for polar and desert regions, Asia north of the Himalayas, some Indonesian islands and some Pacific Islands.

The genus comprises three widespread continental species and many island species including the extinct island species. The widespread species comprise: western barn owl of Europe, western Asia and Africa, the eastern barn owl of Southeast Asia and Australasia, and the American barn owl of the Americas. However, some taxonomic authorities classify barn owls differently, and unify all continental barn owls in to one species. Further research is needed clarify the taxonomies.

The Malayo-Polynesian languages are a subgroup of the Austronesian languages, with approximately 385.5 million speakers. The Malayo-Polynesian languages are spoken by the Austronesian peoples outside of Taiwan, in the island nations of Southeast Asia (Indonesia and the Philippine Archipelago) and the Pacific Ocean, with a smaller number in continental Asia in the areas near the Malay Peninsula, with Cambodia, Vietnam and the Chinese island Hainan as the northwest geographic outlier. Malagasy, spoken on the island of Madagascar off the eastern coast of Africa in the Indian Ocean, is the furthest western outlier.

Many languages of the Malayo-Polynesian family in insular Southeast Asia show the strong influence of Sanskrit, Tamil and Arabic, as the western part of the region has been a stronghold of Hinduism, Buddhism, and, later, Islam.
