石焼き芋屋さん - Yakiimo Truck (roasted sweet potato truck) is sort of like an ice-cream truck that comes around in your neighborhood with ever-so creepy monotone serenade of "Come get your roasted sweet potato~!," blasting and testing the limit of installed megaphones.
The piping hot potato is usually served wrapped in aluminum foil. And once the potato is hand snapped in half or 1/3, the first careful bite is nothing short of greatness, provided you're freezing your butt off in a middle of the frigid cold winter in Japan.
