The English Blog’s Learning English Blog is rather good but only updated every month or two. It has links to materials for a mix of levels.
This is where I found out about Speechyard, which has links to YouTube videos of movie clips and full movies with Google Translate powered subtitles (I’d recommend English subtitles only for Japanese learners). There is a mix of material and is easy to use. Not only that, but you can copy words from the subtitles and use them in practice exercises.
