The caption says she drank these when she was in America and that she wants them to sell it in Japan, so she probably liked it. Japan has weird rules about food and drink sometimes. Like I couldn't get diet coke when I was there because of the sweetener they use or something. It's a similar reason why they don't sell Rice Krispies over there/why the girls like them so much as a novelty.
