100-yen shop

100-yen shops (100円ショップ, hyaku-en shoppu) are common Japanese shops in the vein of American dollar stores. Stocking a variety of items such as decorations, stationery, cup noodles, slippers, containers, batteries, spoons and bowls, electronics, each item is priced at precisely 100 yen, which is considered attractive to Japanese consumers because it can be paid for with a single 100-yen coin. However, the current Japanese consumption tax of 8% (food and drinks) or 10% (other items) is also added, making a 100-yen purchase actually cost 108 or 110 yen. Larger items, like furniture and tools, may also cost more yet are still relatively affordable, usually costing less than 1000 yen.

The four major chains are Daiso, Seria, Watts, and Can Do, which combined have over 5,500 locations across Japan as of 2012. A variation of the 100-yen shops are 99-yen shops. Daiei also operates 88-yen stores. Some shops, such as Lawson 100, specialize in certain items, such as groceries or natural goods, but this is less common than the variety store model.

As of 2018, Daiso has over 2,800 stores throughout Japan, with 20-30 new stores opening every month. One of the largest 100-yen shops is the Daiso in the Tokyo neighborhood of Harajuku. It spans four stories and over 10,500 square feet (980 m²).

Similar shops have opened around other parts of Asia as well, some operated by Japanese companies such as Daiso, which now has branches in 25 countries outside of Japan. In Hong Kong, department stores have opened their own 10-dollar-shops (JPY140) to compete in the market, thus there are now "8-dollar-shops" (JPY110) in Hong Kong, in order to compete with those lower prices.

100-yen shops are able to keep prices down by purchasing goods internationally and in bulk. These goods come from countries with lower production costs, namely China and Thailand.
