It lies specifically between the two larger islands of Honshū and Shikoku. Awaji is the largest island found in the Seto Inland Sea. It serves as a vital geographic link between the major Japanese islands. Today, the island is divided into three municipalities: Awaji, Sumoto, and Minamiawaji.

Geographic features define the island's location and movement of water. The island is separated from Honshū by the Akashi Strait. It is also separated from Shikoku by the Naruto Strait. In the strait between Naruto, Tokushima, and Awaji, the Naruto whirlpools form.

These whirlpools are a notable natural feature of the region. Connectivity to the mainland has changed significantly over time. Since April 5, 1998, the Akashi Kaikyo Bridge has connected Awaji to Kobe on Honshū. This is the second longest suspension bridge in the world. The Kobe-Awaji-Naruto Expressway now provides the main eastern land link between Honshū and Shikoku.

Ancient mythology provides a spiritual history for the island. According to Shinto creation myths, Awaji was the first of the ōyashima islands. These islands were born from the kami Izanagi and Izanami. The island is mentioned in the Kojiki and Nihon Shoki. In these texts, the island is referred to as Onogoro-shima and Awaji-shima. Scholars have different ideas about the name's origin. Motoori Norinaga suggested the name means "the road to" a historic province. This province bordered the Shikoku side of the Naruto Strait. Other interpretations link the name to "millet," or awa. This stems from a story where the kami Sukunabikona climbs a millet stalk on the island.

Political history shows the island was once a distinct administrative region. From the 7th century until the 19th century, it was known as Awaji Province. During this time, it was a part of the Nankaidō region. This historical status lasted for many centuries before the modern municipal system was established. The island's transition from a province to three municipalities marks a major shift in its governance. Today, these local governments manage the areas of Awaji, Sumoto, and Minamiawaji.

Cultural traditions on the island are both old and recognized. Awaji Ningyō Jōruri is a form of traditional puppet theater. This art form is over 500 years old. It is performed every day at the Awaji Puppet Museum in Minamiawaji. This museum is located in the southern part of the island. The puppet performances are designated as an Intangible Cultural Heritage of Japan. While they perform popular traditional dramas, the puppets have origins in religious rituals. Another tradition is Awaji ware, a type of Japanese pottery. A local potter named Minpei began producing this ware in the 1830s. It is also known as Minpei ware.

Modern architecture also defines parts of the island's landscape. The architect Tadao Ando has designed several structures here. These include buildings in Awaji City. One notable example is the Awaji Yumebutai complex. These structures add a modern element to the island's physical environment. The island's landscape is a mix of these modern designs and ancient cultural sites. This blend of old and new makes the island a unique place in Hyōgo Prefecture.

Geological activity has deeply impacted the island's history and landscape. The Nojima Fault is a major fault line that cuts across the island. This fault was responsible for the Great Hanshin Earthquake in 1995. The earthquake was the epicenter for the island. It killed over 5,500 people and caused enormous damage. The northern part of the island experienced severe seismic waves of JMA intensity 7. To help people understand this, a section of the fault was protected. This area became the Nojima Fault Preservation Museum. The museum shows how ground movement cuts across roads, hedges, and other installations. The Nojima Fault was designated a national natural monument in 1998. In 2022, it was also named a IUGS geological heritage site.
