You might have heard that vending machines are everywhere in Japan. True.
And you can get practically anything you need from them. Most likely true.
This vending machine looks like a coin locker. What can you get for 110-200¥? Veggies. Slim pickings today. White radish is available. So is a kind of Japanese mustard spinach called meikena (女池菜).
The vending machine is located right in front of a plot of farmland, but I can't say for sure that that land produced this produce. It's also next to a bus stop. Pretty convenient.
