Here is a site that has enough japanese patterns, knitting, crocheting, and others, to keep a person busy for the rest of their lifetime!
you will need to have japanese fonts installed on your computer, if you do not do a search in windows and you should be able to DL a freebie one. someone a bit more technical then myself would have to explain how to do this.
click on each number and check out the goodies. to get to the pattern you click on the number, then when that page opens up you click on "as for knitting figure" on my computer its a different color then the regular words.
