A Japanese numeral meaning ten thousand, the next degree after *sen* (one thousand), *hyaku* (one hundred), and *juu* (ten). This is also where Japanese diverges from most Western representations of large numbers: for example, one hundred thousand is represented as *juu-man*, literally "ten ten-thousands". This continues with *hyaku-man* (one million; hundred ten-thousands) and *sen-man* (ten million; thousand ten-thousands), until you get to *oku* (one hundred millon; ten thousand ten-thousands).

Can be written as 万, and ten thousand is sometimes written as 1,0000 in more traditional contexts.
