What is an island nation?

An island nation is a country that consists primarily of one or more islands. While some island nations may have small territories on the mainland, the majority of their land mass and population is located on one or more islands. Island nations are often characterised by their distinct cultures, traditions, and languages that have developed in isolation or in close contact with nearby islands or regions. Notable examples of island nations include Japan, Indonesia, the United Kingdom, Madagascar, and New Zealand.
