Another strange combination gaining popularity is the matcha latte, a frothy concoction of matcha green tea and milk. This drink has been popular in cafes for some time now, but recently chilled convenience store versions have started popping up. Asahi launched their Fauchon product late last month which will be followed by MegMilk's matcha latte on Sept. 29.

Purported to have been invented by Kouta Matsuda, owner of Tully's coffee chain, the latte was born from experiments with matcha and an expresso machine. After enjoying some years of popularity in Japan, the drink took off in the States in 2006. Matcha is prized for its health benefits which include being rich in antioxidents and high in fiber.
