Origin

The character 柳 combines the wood radical 木 on the left, which classifies this as a type of tree, with the component 卯 on the right that serves as a sound hint for pronunciation. The wood radical makes sense because a willow is indeed a tree. The 卯 component doesn't contribute meaning here — it simply indicates roughly how the character should sound, similar to how you might guess a word's pronunciation from a familiar-sounding part. Over time, this combination of a meaningful classifier (the tree radical) and a phonetic hint (卯) became the standard way to write the word for willow in Japanese kanji.
