KanjiJLPT N1
Narrow

cramped, narrow, contract, tight

Mnemonic

A beast spots a lobster darting between two boulders. It lunges, but the gap is too narrow! The beast slams face-first into the crevice while the lobster's flat body slips right through. Furious, the beast claws at the narrow crack, but it only wedges tighter.
Additional thoughts
Picture the lobster's flat shell perfectly suited for narrow spaces, while the beast's bulk makes the same gap impossible. The pinching shape of a lobster naturally evokes tightness and confinement.
Quick recall
A beast chases a lobster into a narrow crevice — too tight to follow!
