About HIJMS Nagato (Wreck)
HIJMS Nagato is Bikini Atoll's upside-down battleship wreck, a deep technical dive that turns a wartime relic into one of the Pacific's most dramatic wreck scenes. The hull is huge and inverted, so the wreck reads more like an underwater landmark than a simple ship silhouette. Access is expedition-based and the dive rewards serious planning, because the wreck sits in a remote lagoon and the profile demands decompression discipline.
