Calpis is my favorite none-alcoholic drink in Japan. It available in any combini, but the super size can can only be found in a few vending machine, if you are lucky sometime it only 100yens. Every now and then the company release a new flavor, but the best is by far the original one ( calpis water ) If you might be able to find some in your city’s china town, often go by the name ” Calpico ” but it the exact same thing.
