From now until February 23rd (the day of the Tokyo marathon) at the Hanzomon Joglis Runners Satellite there will be a special Kagome vending machine that sells raw tomatoes.

If tomatoes aren't your thing, there is also a Dole banana vending machine just outside of the JR Tokyo Marunouchi Underground exit.
