Online Japanese Lesson(by NHK)

I found this site by chance ,when searching for japanese kid's show.It offers a variety of Japanese Lessons,you can even download the MP3-Files and the Text as  a .pdf-File for all lessons.I don't really know if it's good or not but at least the first lesson looked promising.I will do some more and write a review of it in the near future.
