Japanese programmers suck because none of them understand english and can't google for help with their programming issues. Thus isolated from documentation and help, they write their crap totally ignorant of any standards or programming guidelines. The resulting code is acceptable to them as long as it sort of runs in Windows with Shift-JIS set as the system character set.
Try running a Japanese program in a non-japanese Windows... and then cry or laugh as it can't even write text on the screen as it's unable to deal with the character sets everyone else uses.
