KanjiJLPT N3
Labor

labor, thank for, reward for, toil, trouble

Mnemonic

A crown sits heavy on a king forced into hard labor. Every ounce of power in his muscles burns as he toils in scorching fields, sweat soaking through royal robes. The crown offers no escape—only aching exhaustion from endless, thankless work.
Additional thoughts
Visualize the kanji structure: crown (冖) on top, power (力) below. A crowned ruler bent over, straining every muscle. True power isn't sitting on a throne—it's the grueling labor underneath the crown that holds everything together.
Quick recall
A crown demands raw power—wearing it means endless labor.
