花 (hana) is a native Japanese word (和語, *wago*) with roots tracing back to Old Japanese *pana*. The kanji 花 was borrowed from Classical Chinese, where it also means "flower," and it replaced the older phonetic spelling 波奈. The character itself depicts a plant (艸, the grass radical 艹) above a transforming form (化), symbolizing a plant in bloom — something that "transforms" into beauty.

花 holds an extraordinary place in Japanese culture. It is central to *hanami* (花見, "flower viewing"), the beloved springtime tradition of gathering under cherry blossom (桜) trees. In classical poetry and literature, 花 alone — without any qualifier — almost always refers specifically to the cherry blossom, considered the quintessential flower of Japan. The word also appears in *ikebana* (生け花), the art of flower arrangement, and in countless proverbs, such as 花より団子 ("dumplings over flowers"), meaning one prefers practical things over beauty.
