Rin

rin, 1/10 sen, 1/10 bu

Mnemonic

From atop a cliff, you gaze down at your native village far below. It appears impossibly small — reduced to a single rin, the tiniest fraction imaginable. The higher you climb, the more the village shrinks, reminding you how minuscule a rin truly is.
Additional thoughts
Imagine the perspective shift: standing on the cliff edge, your native village below dwindles into a nearly invisible speck. That speck is one rin — a thousandth of a whole. Cliff hovering over native village mirrors the kanji structure perfectly.
Quick recall
Your native village seen from a cliff shrinks to a mere rin — an impossibly tiny speck.

Details

The keyword for 厘 is rin. A rin is a traditional Japanese unit of measurement representing an extremely small quantity, equal to one-thousandth of certain base units. It was used in monetary contexts as 1/1000 of a yen and in measurements of length and weight, always denoting a minute, almost negligible amount. The kanji thus conveys the idea of something infinitesimally small or a tiny fraction of a whole.
