What do you think about the censorship of The Cove in Japan?

This short article reads that some cinemas in Japan have censored the documentary The Cove.
For those that don’t know about the film, it’s about this tiny secret area in a coastal village in Japan that was hidden from view and what they were doing to dolphins in that area.
I kind of understand how the Japanese would want this censored. But it is true about that area and if you saw the film you’d understand why it should be seen. Is there anyone who’s in Japan or that area right now that could shed some light on the subject? I’d like to see what kind of reactions you have to this.
