This is so very true, the ad is simply amazing. Citizen revealed they have sent a crew of 40 (!) people to Sendai to shoot it with Yuzuru. The ad was received so enthusiastically they have even revealed the names of very people who created it. But they did it on Twitter so no use for you

And yes, it is mainly for Chinese market as Yuzu is their Brand Ambassador for China (and I think, South East Asia or some parts of it, too, including Hong Kong, Taiwan, some more but I can't remember now exactly which countries). Still, as you can hear below, Yuzu says the last sentence in the full version in English, so yes, I think they have been pretty well aware the ad was going to go viral and interest in it was going to be global.
I haven't seen the full version on YouTube
yet but if you can see Instagram, here it comes (still you need to click on it to start it running and turn the sound on to hear it). Please let me know if it works for you.
