Below the revolving sushi a conveyor belt holds big teacups. I put a teacup under the spigot at my place in the Tokyo Station fast food restaurant. Hot water pours into my cup. But where is the tea?
I give up on the tea and take a plate with one piece of sushi. I tap green powder from a can into a dish the size of a silver dollar and mix in some hot water. I wait -- I know powdered horseradish must set for five minutes. Alas, the liquid does not thicken; there is no piquancy. It tastes like tea.
The powder I tap onto the now lukewarm water floats. The waitress helps as I mime: first put the tea powder into the cup, then add hot water. Nobody says anything--not the sushi master nor the guy eating next to me.
