Does Japan still sell PSP?

Excuse me, I was wondering if you could clarify something for me. I've been looking around for a PlayStation Portable, or PSP as it's commonly known, and I was wondering if Japan is still selling them? I know that it's been a while since the PSP was first released, but I've heard that some countries might still have stock available. So, could you please tell me if Japan is still offering the PSP for sale, and if so, where might I be able to find one? Thank you in advance for your help.
