Hello, this is Chiaki, an interpreter.
One of my favorite things in winter is baked sweet potatoes.
It was very cold last night.
I was on the way home from the station.
At that time, I heard the whistle and the voice of “sweet potatoes~”
That whistle means the potato wagon is around.
They bake potatoes in the special oven with the bed of stones on the wagon.
Stones make them so sweet and tasty.
It’s simple and so tasty Japanese winter dish.
