Kuro5hin have a superb quick introduction to the syntax of the Japanese language , from a geeks perspective.

I did Japanese in high school (gymnasium) in Denmark and loved it. By now of course I’ve forgotten most of it, but can still helpfully manage to embarras myself around Japanese people.

I remember being fond of the grammar, because while it was very different from most European grammar, it was simplicity itself. Do to its clever use of post positions you can really do some kewl perl like one liners in Japanese, where you would have to use several lines in lower level languages like English.
