juu

Juu is a romanization used for the Japanese term 十 and the kana じゅう, both meaning the number ten. The spelling "juu" indicates a long vowel, and in precise transliteration the macron form "jū" is often used. In non-Japanese contexts, Juu may appear as an alternative spelling.

In Japanese, juu forms the basis of numerals and time expressions that involve ten. It appears in phrases such as juu-ji for ten o'clock and juunen for ten years. The numbers from 11 to 19 are typically formed by combining the prefix juu with the individual digits (e.g., juu-ichi for eleven, juu-ni for twelve). The digit ten itself is written as 十 and read jū in most numerals and compounds.

Outside of language use, Juu may be encountered as a personal name, a surname, or a brand or character name in fiction and media. Because romanization conventions vary, Juu can also be rendered as Jū, Ju, or JUU in different texts or contexts.

Etymology and usage: The character 十 is the core symbol meaning ten, and its common on'yomi reading in numerals and compound terms is jū. While the kunyomi is not typically used for standalone ten, 十 appears widely in various numbers and expressions across Japanese.
