日本語のポッドキャスト。
It is difficult to find Japanese Podcasts on itunes that we are able to download in the US, but I found a couple that I think are pretty good.
一番(いちばん)、NHKラジオニュース。
If you type this into itunes you should be able to find it. It is a free news and politics podcast and they speak slow enough to pick up on some words every now and then.

二番(にばん)、特撰寄席はなしびと By フジテレビ
This is a Japanese comedy podcast, I will let you read more about it on your own if you are interested. I like the fact that it is a video podcast and that is a decent quality. He does speak far to fast for me to pick up on anything that he is saying, but it think that it can help with pronunciation.
