I believe Maccha is the real thing. In rotating sushi places you always get it. Along with some picled ginger. I dont know if it is to take the taste of the sushi out (so you can taste a different kind of sushi) or if it is to prevent sickness from eating raw fish (i heard both stories from japanese people so I dont know which to believe)

Anyway, there are many brands of maccha and you might find it online. Its powdered tea, but it is not soluble, so it kinds of rests at the bottom of the cup when you finish drinking it. Its not sweet at all, but is very good when its very hot and outside is freezing.
