The kanji 泉 is a pictograph of water flowing from a rocky source — symbolizing a spring bubbling up. It’s often used in words related to nature, healing (like 温泉), or poetic references to the origin of something.

In place names like 和泉 (いずみ), the reading appears in its kun-yomi form. This kanji also appears in literature and names, often evoking natural purity or emotional depth.

この山やまの裏うらには 小ちいさな 泉いずみが 湧わいています。
A small spring bubbles up behind this mountain.

温泉おんせんに 入はいって 疲つかれが 取とれました。
I soaked in a hot spring and felt completely refreshed.

The on-yomi “セン” is commonly seen in compounds like 温泉 (onsen) and 泉水 (sensui), while the kun-yomi “いずみ” is often used for place names or poetic expressions.
