Here's a story from Japan Today: Just in time for summer, Asahi begins selling Mitsuya Cider served at a slushy -5℃. This is a timely move by Asahi not only because summer is upon us-- and it's going to be blistering-- but also because my wife and I were just mutually bemoaning the lack of Slushies and Icees here in Japan. There may be Slushie-, Slurpee- or Icee-like drinks available (and there's always kakigori), but, if there are, we haven't seen them. Or we have and we're just not aware of it.
After watching a movie where a character buys a Slushie along with some pornography, my wife and I began reminiscing about very cold nearly-frozen drinks with Coke or cherry flavor you drink until they make your head hurt as if your brain suddenly decided to exit through one of your eye sockets.
