As a data point, when I worked in Japan, most of the code was written in English (variable names included - the language was mostly Java or PHP), with heavy commenting in Japanese. Granted, this may have been swayed from the fact that they often worked with Indian developers, but also, a lot of technical language in Japanese is adopted from English. Popular languages there are the same as anywhere else - Ruby's creator is Japanese, and a high school student I know there was being subjected to COBOL. There is a Japanese programming language, Mind, which is a stack language written entirely in Japanese, though I don't think it ever gained popularity. It's kind of sad there hasn't been more exploration into this - there's a lot less impedance mismatch in going from Japanese (or Korean) to postfix than there is going from English to prefix. http://en.wikipedia.org/wiki/Non-English-based_programming_languages http://en.wikipedia.org/wiki/Non-English-based_programming_l...
