KanjiJLPT N1
Ground-Breaking

ground-breaking, open up farmland

Mnemonic

A badger burrows into untamed earth, loosening dense roots. A footballer kicks away massive soil clods like penalty shots. This unlikely duo performs the most Ground-Breaking land reclamation ever seen—wild terrain turned to fertile fields by claw and cleat.
Additional thoughts
Picture the badger's powerful claws ripping through packed soil while the footballer boots enormous dirt chunks downfield. Claw + kick = ground broken. The earth radical sits at the base of the kanji, literally grounding the whole character.
Quick recall
A badger claws raw earth while a footballer kicks clods away—Ground-Breaking teamwork.
