Meaning

日 centers on the sun and the day it defines: the bright celestial body, the period of daylight, and by extension the concept of a full day. The Japan sense is a cultural application of the sun symbol, and the counter for days follows naturally from the day meaning.

Etymology

日 is a pictograph of the sun, originally a circle with a dot or line inside. The modern squared form with a central horizontal stroke is a stylized version of that ancient sun image.

Meaning mnemonic

The rectangular outline is the sun's disk, and the horizontal stroke inside is its bright center. See 日 as a simple drawing of the sun, which gives us day and light.

Reading mnemonic

For ニチ, imagine a sunny day perfect for a picnic with a niche cheese: niche -> ニチ, and the sun shines on your day out.
