i felt japanese was easy to learn. Since it doesn't relate to english in the grammar department, i wasn't getting it confused with language knowledge i already had.
what i did was get a small note book. and then I would drill myself by writing down all the kana symbols. The ones I couldn't remember or took too long to remember I would further drill on by repeatedly copying them until it was burned in my brain. Then I would start over again with all the kana.
I drilled myself much in the same way over kanji, but you should get a kanji workbook from B&N. It will help you learn the radicals, and the patterns of the characters. For months, I used to dril myself continuously on my kanji. I was up to 350-something, which isn't bad for a 1 year american student. now I've lost most of that since I don't use it
