Japan has a network of 858 official roadside rest areas that also serve as stores for local goods and produce. These rest areas are called michi no eki, or road stations. Like train stations car and motorcycle enthusiasts enjoy trying to stop at all of them. Some have restaurants serving some special dish, and most have these blue bins. These contain locally grown vegetables and fruits from the farms near the michi no eki. Typically they are sold at extremely low prices. That big goya in front is only 80 yen. Typically the price tag will also have the farmers name on it also. Locally produced foods are typically cheaper, fresher, tastier and, because they are not shipped 1,000s of miles to distribution centers and markets, better for the environment.
My Mother-in-law makes the best goya with pork and egg stir-fry dish. It's the best.
