1.
reclaimed land; landfill
land that has been created by filling in a body of water or low-lying area with soil, waste, or other materials
Usage
埋立地 can refer to both land reclaimed from the sea for development (common in Japan's coastal cities like Tokyo and Osaka) and waste disposal landfill sites. Context usually makes the meaning clear.
Cultural note
Much of Tokyo's waterfront, including areas like Odaiba and parts of Haneda Airport, was created through land reclamation. These areas face unique challenges such as liquefaction during earthquakes.
