Inspired by a lifelong love of Hayao Miyazaki’s Castle in the Sky, I traveled to Tomogashima, a group of islands in Japan’s Kitan Strait often called “the island of Laputa.” Beyond the familiar photographs lay a place where sacred traditions, military history, and returning nature overlap. From the Fifth Battery’s abandoned gun emplacements to the Third Battery’s vaulted brick passages, this journey follows the traces of those who built, guarded, and lived on the island. Among moss-covered walls and underground shadows, I found both the precision of human craftsmanship and the quiet persistence of a landscape reclaiming its own.
