KanjiJLPT N5
Country

Mnemonic

A radiant ball pulses at the center of a vast walled garden — it is the soul of the country. Without this glowing orb, the nation crumbles. With it, the walls stand firm and the people thrive. Every country is just a walled garden protecting its most precious ball.
Additional thoughts
The outer box radical (walled garden) visibly encloses the ball (jewel) inside. Picture a nation's borders as garden walls, and its sovereignty as a glowing orb at the center that must never be taken.
Quick recall
A ball guarded inside a walled garden is the sacred heart of a country.
