I have a nook color and I use anki droid. I've been reviewing Hiragana and Katakana with it but the characters don't show up correctly. I don't have the time to figure out how to get the Japanese font on it. Is there a file somewhere that has the kana as individual jpgs?

Click on the picture to the right (either kana)
If there are many formats available, choose what you want.

Or... just write/copy them all as text and photoshop them.

If you're using Anki 2 you can just put the font in your media directory and sync it, and make use of the font in the card template. See this.

Thanks for the quick replies. I'll try these solutions out.
