Morphology

Japan + trench

The compound is a straightforward locative naming pattern: 'Japan' specifies the location and 'trench' names a deep ocean depression. A B1 learner who knows both words can infer it refers to a deep ocean trench near Japan, a compositional and cross-linguistically common construction.

Etymology

Japan Trench comes from the image of a long, very deep trench in the sea next to Japan, like a huge 'ditch' on the ocean floor. Because this deep place is where the sea floor can slip and move, the Japan Trench is connected to strong earthquakes and tsunamis today.
