Kagenan

Kagenan [判洒; かげなん] is the smallest island in the Zōku archipelaego of Zōhai Prefecture. Most of the island's small surface area is covered by the city of Kage.
The central region of Kagenan was originally a number of smaller fishing villages which were merged into the city of Kage in 1955. As a result of this merger, many local industries and fishing ports were abandoned or fell into decline. The west coast of the island, once a thriving hub of commercial fishing and agriculture, has since become poverty-stricken and delapidated. Much of the infrastructure outside the city centre had to be completely renovated in 2017, following a typhoon which destroyed large swathes of Kage's outskirts.
Kagenan is connected to the larger island of Dainan by Atate Bridge. In order to get to Shinan, residents must take a ferry from Hachikage Harbour, the largest port on the island.
