Shioyasaki lighthouse is an unassuming white structure perched atop a rocky outcrop overlooking Japan's Pacific coast. For over a century, the lighthouse―closely associated with Fukushima Prefecture―has served as an essential navigational aid for passing ships, imparting an important sense of security for those out at sea. Beyond being a symbol of nautical safety, the lighthouse also bears the scars of the earthquake and tsunami that devastated Japan's Tohoku region five years ago. Briefly shut down in the aftermath of those events, the lighthouse was relit once again, and now serves as a reminder of the resilience of Tohoku's local communities.
