The person who forwarded this to me said the soundtrack was in Japanese. I get the impression it's Chinese, myself. The Sinophones here can tell me which, if they so desire.
Even if you can't understand what's being said, the illusions are still amazing (unless it's trick camera work; anyone more familiar with that feel free to pipe up, too), and you can appreciate them without knowing what's being said. Kinda long (almost 7 minutes), but stick it out to the end; it's worth it.
