if you have an iPhone and you are at all interested in Japanese, buy this app. it's simply called "Japanese." best features are its ease of looking up Kanji and it can help you study for the JLPT. it's a little expensive, 2300 yen, but well worth it. I used to use a different dictionary but I will never again. Japanese has tons more words and tons more functions an is tons easier to use, get it!
