About this map

Japan Island and the adjacent Japan Outside Pond occupy a small fraction of this maritime landscape in Plaquemines Parish. The map reveals an area dominated by the open waters of the Gulf of America, showing the modern shoreline and maritime boundaries as they exist in 2025. This survey, part of the USGS 7.5-minute series, provides a clear view of the relationship between the fragile coastal landforms and the surrounding sea. The limited land features suggest a region shaped primarily by marine processes, where specific named points like Japan Island serve as vital markers for navigation and local geography in the Mississippi River delta region.
