The Japanese are one of the strictest cultures in the world in regards to the freshness of food. Their concept of chisan chishou involves the careful caring and growing of vegetables and fruits so that each item is organically raised and tenderly cared for before it gets to your table that same day.
This also means that their agricultural projects are typically of a smaller scale, and no industrial farms are anywear near your local grocer.
