Pocari Sweat is so good. I always grab a bottle anytime we go to the japanese store outside chicago. I assumed it was a fake anime product like the way they always turn pepsi into bepsi or something, but no it's real and it's delicious.
Aquarius (essentially grapefruit, somewhere between soda and sparkling water) is a bit of an acquired taste. And when my school's Japanese club visited in high school, boy, did we acquire it. Lots of "Pocari Sweat" and "Calpis" double entendres flying around, too.
