Gashapon (ガチャポン in katakana - more accurately, gachapon), also referred to as "Candy toy" or "trading toy", is a Japanese onomatopoeia, made up of two sounds: "gacha" for the turning of a crank on a toy vending machine, and "pon" for the sound of the toy capsule dropping into the receptacle. It is collectively used to describe both the machines themselves, and any toy obtained from them. Though "gashapon" is the more common spelling as seen in the United States, it is primarily a corruption of gachapon, which is more technically accurate. "Gachapon" is a far more prevalent spelling/pronunciation in Japan than "gashapon," which is rarely, if ever, seen.
Gashapon machines are similar to the coin-op toy vending machines, seen outside of grocery stores and other retailers in the United States. While coin-op vending toys are usually cheap, low-quality products, sold for a quarter or 50 cents, Japanese Gashapon can cost anywhere from 100 - 500 yen (Equal to $1–$5 US) and are normally a much higher quality product.
