A typical example would be a small hut or stall by the side of a field stocked with some fruit and vegetables, with a note on a box saying, “Please put the money in here.”
After selling their crops to the market, farmers might then here sell the leftovers from their own personal supply. This means that the vegetables sometimes have markings or otherwise is not in the “perfect” condition demanded for sale on the regular market.
Nerima ward even has a website mapping unmanned shops, so you can see where there are stalls and what kinds of veggies are for sale there. There are over 120 unmanned stores registered.
