I've been relying on japanese-japanese dictionaries for a while, and they work best IMHO once you're past a certain level. Also, most good non-jp-jp resources are in english, and, after all, english is not my native language either, so I might as well deal with everything in japanese. I just wish I could find an app that does everything in japanese, but I never found one. Tried a few, but there are so many that it's hard to find something decent. The result is that I haven't actually actively studied japanese for a while, and rely on "passive" learning from talking, reading and watching TV (I live in Japan, that helps). I'm actually sufficiently annoyed that I'm not retaining as much as I would like that I'm considering writing a web app to handle my own learning.

Edit: by the way, I once stumbled upon an online dictionary that also showed the "standard" intonation for words (something that I've very rarely seen mentioned), but I can't find it again :(
