Mineral water consumption in Japan

I use a built-in water purifier for drinking water at home, so consumption of mineral water is limited to the occasional half-litre bottle at the weekends when going out. To see how the Japanese use it, DIMSDRIVE Research conducted a survey into this topic of mineral water.
Demographics
Between the 19th and 27th of March 2008 8,383 members of the DIMSDRIVE Monitor group completed a private internet-based questionnaire. 52.9% of the sample were female, 1.3% in their teens, 14.9% in their twenties, 33.3% in their thirties, 29.9% in their forties, 14.7% in their fifties, and 5.9% aged sixty or older. 51.7% lived in a house, 47.0% in a flat (apartment), and 1.3% other. By family size, 13.0% lived alone, 23.8% with one other, 25.1% with two others, 24.1% with three others, and 14.0% with four or more other people.
The pictured bottle sounds even less appealing than the Engrish standbys of Pocari Sweat and Calpis, but it’s actually mineral water for your four-legged friend, not Dogpis!
Getting back on track, my purchased brand is determined by seeing which one is 110 yen in the convenience store, although I can’t remember the brand right now, but it is a Japanese one. I’ve tried the oxygenised water a couple of times, but I didn’t really notice any difference.
