Coke or Pepsi? in Japan


Coke or Pepsi? graph of japanese statisticsOne of the eternal questions is “Coke or Pepsi?”, which is also one question from this survey from iShare on cola. I was going to joke that tomorrow I will be doing “Boxers or briefs?”, but then I remembered that I’d already done that one!


Between the 29th of August and the 1st of September 2008 464 members of the CLUB BBQ free email forwarding service completed a private online survey. 54.7% of the sample were male, 14.2% in their twenties, 47.4% in their thirties, 28.2% in their forties, and 10.1% in their teens or aged fifty or older.

I’m a Diet Coke person myself, which in Japan actually contains a little bit of sugar. I can cope with Diet Pepsi, but the full sugar efforts are disgusting. The Diet Coke with added vitamins is pretty awful too. How about you?

Diet or full calorie cola?

    I prefer Coke, but once in a while, a Pepsi makes a refreshing change! 🙂
