In Japanese supermarkets, it is common to buy a single apple, one onion, or one cucumber.
To Japanese shoppers, this does not feel like a special way of selling food. Items sold individually often sit next to bags containing several pieces, and people simply choose whichever amount they need.
One reason is that buying only what you need is convenient. Someone living alone may not be able to use up a large bag of vegetables. Even families may shop this way: two onions for tonight’s curry, or one tomato for a salad.
Japan’s aging population and large number of people living alone also make it especially useful to be able to buy in small quantities. More elderly people now live alone or in elderly-only households, and the issue is not just whether they can finish the food. Carrying home a large amount of heavy produce can itself be difficult.
Single-person households have also increased for other reasons, including later marriage and a higher proportion of people who remain unmarried. For someone cooking for one, a large family-sized bag may simply contain more food than they need for the next few days.
Fresh produce also does not last forever. Buying a large quantity may be cheaper per item, but it is not necessarily a bargain if some of it ends up being thrown away. Smaller quantities can make it easier to avoid wasting food.
Buying produce individually also lets shoppers choose by size, color, or ripeness. With fruit, for example, someone may want just one piece in particularly good condition rather than several at once.
Of course, fruits and vegetables in Japan are not always sold individually. Onions, potatoes, and mandarins are also commonly sold in bags. Large vegetables such as cabbage or napa cabbage may be sold whole, but also in halves or quarters.
So the important point is not individual sales themselves, but the ability to choose fairly precisely how much to buy.
And this is not unique to Japan. Supermarkets and markets in many other countries also sell fruits and vegetables individually or by weight.
If small-quantity sales seem especially noticeable in Japan, it is not because Japan has a unique system. Rather, with an aging population and many single-person households, being able to buy only what you need—and carry it home without unnecessary burden—fits well with the way many people shop in everyday life.
Buying one item is not a special option reserved for people who live alone. Choosing among individual items, small packs, and larger bags according to what you need is simply a normal part of grocery shopping in Japan.
