I am actually traveling in Kyoto at the moment and almost everywhere you order green tea (vending machines, restaurants, etc) you get it with toasted rice flavour. I did not like the flavour first time I had it back in Vanuatu. But here I like it a lot, not sure if it is due to tea quality or my changing tastes or probably both. Another side note is that in most Japanese restaurants you get served hot green tea free which is a nice tradition, all you have to do is ask for hotto Ocha (not matcha).
