Tree or happy
Kio is a Japanese name with multiple potential meanings depending on the kanji used, most commonly associated with 'tree' or 'happiness.' In some contexts, it is also considered a shortened or modern variation of longer names like Kiyoshi. Its brevity and vowel-heavy sound make it appealing to parents looking for a minimalist, cross-cultural choice.
