Meaning

Tidal flat; mudflat. A coastal area of soft sediment that is exposed at low tide and submerged at high tide, serving as a vital habitat for marine organisms and migratory birds.

A noun combining 干 (to drain or dry out) and 潟 (lagoon or tidal inlet). 干潟 ecosystems are among the most biologically productive in the world, supporting shellfish, wading birds, and juvenile fish. In Japan, many tidal flats were lost to land reclamation during the post-war economic boom, and their ecological restoration has become a significant environmental policy concern.

Examples

1. 干潟は渡り鳥の重要な餌場であり、生態系の保全が求められている。 Tidal flats are an important feeding ground for migratory birds, and their ecological conservation is urgently needed.
2. 干潮のたびに広がる干潟には、カニやアサリなどの生物が豊富に生息する。 The tidal flats that spread out with every low tide are home to an abundance of creatures such as crabs and clams.
