We also have these things called mujin hanbai. Mujin means something like 'no person' or 'unmanned' and hanbai means "to sell". And that is exactly what they are. The farmers build them and leave them up all year round. From here they sell any extra fruit or vegetables they've picked that morning. Here's a picture of one taken near our house. It looks like it has onions and radishes and potatoes today.
What I like about them is that they are all done on the honor system. You go, pay your one hundred yen (or whatever price is written), take your veggies and go. There is a nice handwritten sign that thanks you for your business.
Here's one that is even closer to my house. It sells seasonal flowers. Sometimes when I'm working in the garden and discover a pot that needs filling, I'll grab a handful of change and walk over here to pick up some color.
You can see the little box for the money as well as (below) a plastic bag full of more plastic bags to help you carry your flowers home. I've even seen mujin hanbai that sell cow poop.
What never ceases to amaze me though is that no one steals this stuff. No one takes the vegetables or the fruit or the flowers. No one breaks into the little box to swipe the change. It makes me feel like a deviant to even think that anyone would be tempted. Because when I quiz friends they say, "Why of course no one would steal the stuff! It isn't theirs. Why would they?" Well, I can understand no one pilfering the cow manure but most of the time this stuff stays out all night long. And you're telling me no crazed teenager hasn't ripped off some tomatoes and ruined a house? Nope. Wow.
I just really, really like that this system works.
