If you order green tea in Thailand you get a long drink in a plastic cup that resembles a sweet, frozen shake. (Then you can put the cup in a plastic bag, hang it on the steering rod of your motorbike, drive around and sip it with a thick straw on hot days.)
The Thai green tea is very different from Japanese and Chinese (usually hot) green tea. The Thai drink is light green and completely opaque.
I read that Thais use "green tea powder", condensed milk, "oriental spices", crushed ice and more to produce this shake.
When I drink this I remember having been served "similar" in Japan. Opaque, green tea in small clay cups. Much more filled with "small particles" than is "normal" tea. It was hot and not sweet, at least as I remember.
When I Google I just find entries like Oolong tea which is not what I am looking for. Oolong tea is clear and more resembles traditional tea.
My question mostly relates to what I have had in Japan. What is this brew that is green but differs very much from "normal" green tea by being opaque?
