I was just reading in Excite Japan what looks like and ad for Vitaminwater. The article, or infomercial, says that the long wait is over, the beverage prefer by celebrities is now in Japan.
Japan does not have a need for another drink, especially vitamin water. In Japan there are already too many of this type of drinks that promise health benefits. Japan has diet water, yes diet water, it sounds funny, but it is true. I am not a fan of specialty waters including Vitaminwater by Glaceau owned as I understand by Coke.

A lot of people in this land, that in the not so far past had only skinny people, are highly concerned about their health and looks. They are also very interested in new products especially if they come from the USA. The Japanese are now bigger than previous generations not only in height, but also in weight and this drink will not help their health nor their size.
