Vice:
Though you mentioned being able to use other software, to make this easier to answer, let's assume your main (only) purpose for getting a Zaurus would be for use as as a Japanese dictionary/study tool.
One big question then comes to mind... do you plan to continue studying Japanese after your year in Japan is up? If not, the Zaurus might not be the best choice, financially speaking. If you really want a dictionary that allows hand-drawn input, you might be better off getting one of Sharp's older non-Linux Zaurus models, some of which can apparently be bought for less than $100. As you already have a Wordtank, the two together should be more than enough to get you through a year here.
If you do plan to continue studying Japanese, the Linux Zaurus line has plenty of tools to cover most needs. Available software includes sljisho (included on Cx60 models), zdict (C3000's dictionary software), zten, zbedic, kanjinirvana, and my own knQuiz (*plug*). In addition, you can also use the Zaurus to read Japanese ebooks, manga, and webpages (whether live or saved locally).
Is it worth getting the C3000? The selling point in your case (aside from the included dictionaries) would be the internal 4GB microdrive. If you plan to carry a lot of data with you, a large CF/Microdrive or SD card is necessary - my dictionary directory alone takes up 1.6GB.
I would suggest try-before-buy, if possible. In fact, you might be better off waiting until you get to Japan before you buy one; it will give you a chance to see what's available, and by that time prices will probably have dropped a bit.
Of course, if you're really just looking for an excuse to buy a new toy, and you've got money burning a hole in your pocket, then I don't know if my advice really makes a difference (^_^)
(P.S.: As I was writing this, I noticed Razzle beat me to the punch. One thing to note, though, is that many (most?) of the dictionary files listed on ZOK can be used on the Linux series. One place where the older models _may_ fair better than the Linux models, though, is outdoors - the screens on the Linux models are hard to read outside. An old MI model (black and white?) may work better.)
