Stories, Articles, Journal Entries, History Lessons... you name it. Original Japanese content that intermediate and advanced students of Japanese can use to get fluent.
Use the text and the audio together to practice speaking with language shadowing. Or, just focus on the reading portion. You're an intermediate/advanced student of Japanese, so you can choose what to focus on.
Use the provided translations to check to see if you were correct, understand the text better, or just plain cheat. Don't do too much of that last one, though.
The content you use to study with is actually interesting and all original. Listen to conversations between a mother and son. Read the fictional tale of a hikikomori who loses everything because he can't leave his home. Or, get converted to Aum Buddhism (I'm pretty sure one of the writers is trying to do this to you, no joke, be careful).
