It's been such a long time since I added a new vending machine to this web site, so here I present the heated food vending machine found at Tokyo Big Sight (amongst other locations).
My personal review of the fries available from the machine: they are edible.
If you're interested in the English legend across the lower section of the machine, it reads: "Your favourite menu is available for 24 hours. The basics of 24-hour hot menu is 'hot and palatable at any time and quickly'."
