Both Shonagon and Chunagon are the web interfaces to retrieve BCCWJ.
You can use Shonagon without registration, but it offers only a simple search function (No POS search). You need to register to use Chunagon, where you can conduct more advanced searches using POS tags.
And if you like to access the text data directly, you need to buy the DVD edition.
