A friend recently told me about nihongoresources.com. It looks like it has a number of things of interest to students of the Japanese language:
12 lessons for complete beginners (currently only the first 4 are done). Looks like you need to spend a bit of time getting confortable with hiragana and katakana first, which is intimidating but I think is definitely a good idea.
General Japanese-English and English-Japanese dictionaries, as well as dictionaries for kanji, names, particles, and even onomatopoeia. These are (of course) based off the work of Jim Breen, who provides the excellent wwwjdic that I currently use.
Jouyou kanji lists
The 1945 standard kanji that Japanese are supposed to learn by the time they finish high school. The lists are broken into levels 1-6, plus general use, and the site allows you to customise the amount of information shown about each kanji (currently only level 1 allows customisation).
But the highlight of the site (at least for me)…
An amazing Introduction to Japanese Syntax, Grammar and Language that’s 285 pages long, and must have taken a huge amount of effort to produce. Based on the author’s study of Japanese at University, it looks like a very useful reference, especially for intermediate or advanced students. I’ll be using this to try to check and re-enforce my understanding of some of the tricky areas of the language (most of it really!). If only I knew enough English< grammar to understand all the terms he uses!
Well worth a look…
As always, がんばってね！
Updated May 2007: as Pomax (the author of the site) notes, the onomatopoeia dictionary is his own work. I’ve also updated the online link to the grammar book.
