Japanesepod101
was a Podcast I listened to it teaches you Japanese phrases and then puts the phrase in to a conversation.Next in the podcast they repeat vocabulary words in Japanese and translate them to English. Then they go through grammar. Then they use the grammar word in different sentences. I found that this podcast is very useful because it teaches practical vocabulary and phrase you could use everyday. Also they repeat the main words and annunciate them clearly.

Japancast
This podcast starts with a conversation in Japanese then it goes through vocabulary that was spoken in the conversation. They go through the vocabulary word 3 or more times before moving on to other vocabulary words.I think this podcast is good for learning vocabulary but not very helpful for learning sentences in Japanese.

One Minute Japanese
In this podcast they spend one minute teaching you Japanese words or phrases that you can practice on your own. I think that this podcast is good for basic vocabulary and phrases. I would strongly recamend this podcast for beginner Japanese learners and as a great way to advance your vocabulary for intermediate and advanced levels of Japanese.

There are many more podcasts that are available these are only the ones I looked at.
