金　土　曜　朝　昼

金 depicts nuggets of gold buried under the earth. The top part shows a mound or covering, the middle strokes are the soil layer, and the two dots at the bottom represent glittering gold nuggets hidden beneath. What shines underground is precious metal.

土 shows a small mound of earth rising from the ground. The bottom horizontal stroke is the ground surface, the vertical stroke is a lump of soil pushing upward, and the top stroke is the rounded top of the mound. It evokes the basic, fertile earth from which plants grow.

曜 is built from 日 (sun) on the left and 翟 (a brilliant pheasant displaying its feathers) on the right. Together they evoke the radiant brightness of celestial bodies. In ancient Chinese astronomy, the seven heavenly bodies each governed one day — 曜 captures that cosmic glow.

朝 is a remarkably vivid time-of-day kanji. It shows the sun (日) rising between two plants or reeds, with the moon (月) still visible on the right — that precise moment when the sun has just risen but the moon hasn't fully set. Dawn, perfectly captured in strokes.

昼 combines a brush stroke marker at the top with 日 (sun) at the bottom. The original idea was a sundial or shadow-stick used to measure noon — the moment the sun casts no shadow, marking the bright peak of the day.
