Awaji Island
Largest island of the Seto Inland Sea, first created in Shinto myth.
via Wikipedia: Awaji Island · see source
Awaji Island lies in Hyōgo Prefecture, within the eastern Seto Inland Sea, sandwiched between Honshū and Shikoku. Covering 592.17 square kilometers, it is the largest island in that sea. The Akashi Strait separates it from Honshū, while the Naruto Strait divides it from Shikoku. Since April 5, 1998, the Akashi Kaikyo Bridge—the world’s second-longest suspension bridge—has linked it to Kobe on Honshū, and the Kobe-Awaji-Naruto Expressway now serves as the main eastern land route between Honshū and Shikoku. In the Naruto Strait, between Naruto on Shikoku and Awaji, the famous Naruto whirlpools form.
The island’s name has sparked debate. Scholar Motoori Norinaga suggested it means “the road to Awa,” referring to the historic province on the Shikoku side of the strait (now part of Tokushima Prefecture), but this is contested. Others, like Tsugita Uruu, trace the word “awa” to “millet,” based on a myth in the Kojiki and Nihon Shoki where the kami Sukunabikona climbs a millet stalk there. In those texts, the island is called Awaji no Honosawake no Shima and Awaji-shima, and it appears as the first island created in Japan according to Shinto creation myth, born from the kami Izanagi and Izanami.
Geologically, the Nojima Fault cuts across Awaji. This fault caused the 1995 Great Hanshin earthquake, which killed over 5,500 people and brought severe shaking of JMA intensity 7 to the northern part of the island. A preserved section of the fault, now part of the Nojima Fault Preservation Museum in the Hokudancho Earthquake Memorial Park, shows how the ground shifted, cutting through roads and hedges. Elsewhere, the fault is less visible. The Onaruto Bridge Memorial Museum and the Uzushio Science Museum are located near Fukura.
Historically, Awaji was its own province from the 7th to the 19th century, part of the Nankaidō region. Today, it comprises three municipalities: Awaji, Sumoto, and Minamiawaji, all within Hyōgo Prefecture. The island is home to Awaji Ningyō Jōruri, a traditional puppet theater over 500 years old, performed daily at the Awaji Ningyō Jōruri Hall in Minamiawaji. Designated an Intangible Cultural Heritage of Japan, it began in religious rituals and now stages popular dramas. Starting in the 1830s, potter Minpei developed Awaji ware (also called Minpei ware), a distinct style of Japanese pottery. Architect Tadao Ando has designed several structures on the island, including the Hompuku-ji water temple and the Awaji Yumebutai complex, both in Awaji City. The 1995 earthquake’s epicenter was on Awaji, and the Nojima Fault was named a national natural monument in 1998 and a IUGS geological heritage site in 2022.

Lore & Background
According to the creation myth in Shinto, Awaji was the first of the ōyashima islands born from the kami Izanagi and Izanami. In the Kojiki and Nihon Shoki, the island is referred to as Awaji no Honosawake no Shima (淡道之穂之狭別嶋(あはぢのほのさわけのしま)) and Awaji-shima (淡路洲). Some scholars, such as Motoori Norinaga, have claimed that the name means 'the road to Awa', the historic province bordering the Shikoku side of the Naruto Strait, although this etymology is disputed. Others, including Tsugita Uruu, have interpreted the historical meaning of awa as 粟 'millet', due to a story where the kami Sukunabikona climbs a millet stalk on the island. Awaji constituted a province between the 7th and the 19th century, Awaji Province, and was a part of Nankaidō. In 1995, Awaji Island was the epicenter of the Great Hanshin Earthquake, which killed over 5,500 people. The earthquake was due to the Nojima Fault, located near the epicenter, which was designated a national natural monument in 1998. In 2022, it was designated a IUGS geological heritage site. A section of the fault was protected and turned into the Nojima Fault Preservation Museum in the Hokudancho Earthquake Memorial Park. Cultural traditions include Awaji Ningyō Jōruri, a form of traditional puppet theater over 500 years old, performed daily in the Awaji Ningyō Jōruri Hall in Minamiawaji. It is designated an Intangible Cultural Heritage of Japan and has its origins in religious rituals. Starting in the 1830s, the local potter Minpei started producing what would come to be known as Awaji ware, also known as Minpei ware. Architect Tadao Ando has designed several structures on the island, including Hompuku-ji water temple and the Awaji Yumebutai complex, both located in Awaji City.
Reader's Guide
Awaji Island holds a unique place in Japanese history and culture. As the first island created in Shinto myth, it is foundational to Japan's creation narrative. Its historical role as Awaji Province from the 7th to 19th centuries underscores its administrative importance within Nankaidō. The island's modern significance is shaped by the 1995 Great Hanshin earthquake, which killed over 5,500 people and was caused by the Nojima Fault. The Nojima Fault Preservation Museum in the Hokudancho Earthquake Memorial Park shows how the movement in the ground cuts across roads, hedges and other installations. The fault was designated a national natural monument in 1998 and a IUGS geological heritage site in 2022. The Akashi Kaikyo Bridge, completed on April 5, 1998, connected the island to Kobe on Honshū and is the second longest suspension bridge in the world. Since its completion, the Kobe-Awaji-Naruto Expressway across the island has been the main eastern land link between Honshū and Shikoku. The Naruto whirlpools form in the strait between Naruto, Tokushima and Awaji. The Onaruto Bridge Memorial Museum and the Uzushio Science Museum are located near Fukura. Culturally, Awaji Ningyō Jōruri represents a living tradition of puppet theater over five centuries old, recognized as an Intangible Cultural Heritage of Japan, with origins in religious rituals. The island also contributed to Japanese ceramics through Awaji ware, starting in the 1830s with potter Minpei. Architect Tadao Ando designed several structures on the island, including Hompuku-ji water temple and the Awaji Yumebutai complex. Today the island consists of three municipalities: Awaji, Sumoto, and Minamiawaji.
