I bought a book that is written in Japanese. It helps me to get this book out and look at the characters (hiragana, katakana and kanji) and when I find one I recognise, I say it out loud…as good as I can. I have severe trouble saying the “dzi,” “dzu,” “rya,” “ryu,” “ryo,” no matter how much I pronounce them. At any rate, doing this for even five minutes has made it MUCH easier to recognise them for myself. A solution to people who do not have the monetary ability to buy a book is to visit websites from Japan or like http://www.kinokuniya.com/us/ and do the same thing. I just wanted to suggest this because it has helped me SO MUCH.
