I drink a lot. Not alcohol, but carbonated beverages. I have an addiction to being well-hydrated. I like to think it's hereditary, because insofar as I know, none of my relatives has ever died from dehydration. As you can imagine, Japan has different companies and, therefore, different brands of sports drinks, soda pop, etc. Though both Coke and Pepsi have strong followings here, they are not the only game in town. While you can find Coca-Cola and Sprite on the shelves of grocery stores, it is somewhat tougher to find Mountain Dew and Pepsi. Additionally, there are tons of Japan-specific flavors like (believe it) Ice Cucumber Pepsi.
Mellow Yellow existed until I came to Japan. It's Coca-Cola's answer to Mountain Dew, but since Mountain Dew is so scarce here, this drink is my only option. It was re-branded in June of 2011 in hopes of inspiring a larger following overseas. So far, at least in my hometown, it's not doing very well. It is not carried at my local grocery store and can only be found in vending machines or at convenience stores.
If you want to know what it tastes like, imagine regular Mountain Dew. I'm no gourmet, and my pallette doesn't discriminate, so I don't have a list of words to describe the essence of divine cuisine. This drink tastes like warm Mountain Dew. Not great, but tolerable.
Yep, "Gulp Melon Cream Soda!" It's delicious and filling, and kind of tastes like a combination of melon soda and ice cream, which I'm sure was their intention. It says "Sapporo" on the bottle, so I assume it's produced either in the city of Sapporo or by the Sapporo Brewery, which ironically no longer brews in Sapporo, haha.
Next time, I'll try to cover more popular beverages. These are all less-than-famous famous brands. The heavy hitters are drinks like Pocari Sweat, Calpis, C.C. Lemon, Aquarius, Nachan, Boss Coffee, and Ramune. Most of them taste pretty good, too.
