Radical
Leg

Mnemonic

Picture a single leg standing upright on a stage. A spotlight hits it. The audience gasps—it's the most perfect leg they've ever seen. It doesn't need anything else. One leg, standing alone, is all you need to remember this kanji.
Additional thoughts
This kanji is its own radical. The shape itself resembles a leg. Just picture a lone leg standing proud—simple and self-referential.
Quick recall
A lone leg on stage IS the leg kanji—it represents itself perfectly.
