One question I sometimes hear from non-Japanese who work at Japanese companies is, "How do I convince my Japanese colleagues I'm right?" This can be alternatively phrased as "What are the best ways to argue, negotiate or debate with Japanese people?"
Whenever I'm asked this question, I'm tempted to simply reply, "You can't" or, rather, "You really shouldn't." It's not that it's impossible to convince a Japanese person of an idea or course of action, but more that it's not likely to work if you go about it the way you've been taught back home.
For people from many Western countries, solving problems by debating them comes naturally, because that is how they are trained to do it at school. In my case, growing up in the United States, a large part of the English instruction at my junior high and high school was about how to do "persuasive writing" intended to convince the reader of an argument, and most classes were discussion-based.
