Kyūshū
Under the Gokishichidō system, the island of Kyūshū was a part of the region known as Saikaidō. It was a part of this region from the 7th century until the middle of the 1800s. Around 1905, it was made into its own region. In the modern system, Kyūshū and the small islands around it are a part of the Kyūshū region.
