KanjiJLPT N3
Usual

usual, ordinary, normal, common, regular, continually, always, long-lasting

Mnemonic

Every adventurer has a usual routine: wrapping a towel around their neck before heading out. No matter the terrain—desert, jungle, mountain—the towel is always there. Other gear rotates, but the towel stays. It's the usual, unchanging constant of adventure life.
Additional thoughts
Picture a rugged explorer who swaps weapons, boots, and maps constantly—but the towel-scarf around his neck never changes. That permanence is what makes it his usual. Adventurer on top, towel on the bottom, just like the kanji.
Quick recall
An adventurer's towel is their usual, unchanging constant.

Details

The keyword for 常 is usual. This kanji conveys the sense of something that is ordinary, constant, and unchanging over time. It refers to what is normal, habitual, or perpetual—the regular state of affairs that one comes to expect. It carries connotations of permanence and continuity, describing conditions or behaviors that remain steady and consistent rather than exceptional or temporary.
