(The Business of Having Faith in Humanity No.1) Unattended Vegetable Stands Use the Honor System
You see heaps of fresh vegetables sitting on the roadside, and no vendor in sight. The situation seems to be dangerously tempting.
Yet, shoppers who use this unique system known as oki yasai, which literally means “leaving vegetables” at an unattended roadside stand, do leave the asking price in the money box, believe it or not.
This method of doing business, known as senyou kouri or “use first, pay later”, was started some 300 years ago by medicine merchants from Toyama Prefecture who sold household drugs throughout Japan, something that continues to this day.
Using a similar strategy, some snack-food manufacturers leave candy bars and other snack items in offices at no charge, on the understanding that payment for consumed items will be collected later when they come to replenish the supply. This business model, while limited to transactions involving small amounts of money, rests on the seller’s trust in the buyers’ honesty.

An unattended vegetable stand. It may be a familiar sight for the Japanese, but the more you think about the system, the weirder it gets.

The farms scattered throughout Tokyo’s residential neighborhoods grow a wide variety of produce in their small plots of land.
Oki-yasai is trusted by shoppers, who love the freshness of just-harvested vegetables and the assurance derived from knowing who produce them. One lady I met during my field trip informed me that she sometimes calls up a local farmer with an unmanned stand, telling him to leave certain vegetables she needs for the next day at the stand. Little did I know that you can also make a “reservation” for vegetables you want. But I guess the farmer will just “leave” the vegetables for you – un-earmarked. What if someone else grabs the veggies before you do? The lady was all smiles when she told me of this secret, and I didn’t dare say anything skeptical to her for fear that I would rain on her parade.
The farms I visited for this article are situated in Tokyo’s Setagaya Ward. Setagaya is known for its exclusive residential sections, but a limited number of farms and forests still remain. Over 80 percent of the farms in Setagaya are smaller than 50 acres. According to Satoshi Kaneko of JA Chuo’s Kinuta District, farmers in Setagaya typically produce small quantities of a variety of vegetables, which are mostly distributed locally through direct sales by the farmers themselves and group sales organized by local agricultural cooperatives.
So oki-yasai is a source of income for farmers, but they are willing to leave their place of business unattended. With no one watching over the merchandise or the money tendered, the system does not work unless the seller trusts in the honesty of strangers. The rate of collection is fairly high at 80 to 90 percent, but it is not 100 percent. To cope with theft, a growing number of farmers install vending machines styled in the fashion of coin-operated lockers. This guarantees money collection, but patrons complain that they do not get to touch and feel the vegetables before they buy.

Patrons love the freshness and reasonable price of the local produce at the stand. Brisk sales begin as soon as vegetables arrive at the stand.

All vegetables on sale are harvested that very morning. Bright and lively colors abound. Sales end when the supply is sold out. Farmers do not replenish vegetables until the next day.
