In 1994, Nakajima Corporation introduced Pickles as part of the Spice Mix Series, based on the concept of "making fashionable plush toys as general goods". The Spice Mix Series was developed in 1993 as a series of general goods plush toys, starting with bears and dogs, and was named after the original fabric made by curling acrylic thread and then mixing and weaving it, resulting in a distinct feel from ordinary plush fabric. Eventually, Pickles became the only character in the series still in production. According to the official bio, Pickles was born on 1 June 1994, around the beginning of the rainy season. Pickles claims to hail from Qua Mei Dou,
France, a wordplay on
Kameidō, the location of Nakajima Corporation head office. Pickles' gender is "secret", and Pickles is "one
cucumber" in height and "two cucumbers" in weight. In 2016, the company started a crowdfunding campaign for a Pickles picture book, which proceeds would be partially donated for the reconstruction of areas affected by the 2011 Tōhoku and
2016 Kumamoto earthquakes. The campaign collected 6.45 million yen. Pickles has been part of the tourism marketing efforts of the
Northern Mariana Islands, and special edition plush toys were released in collaboration with the Marianas Visitors Authority in 2017 and 2018. In December 2018, a series of limited edition Pickles dolls was released in collaboration with the girl group
Hiragana Keyakizaka46. Pickles has also been featured on the variety show
Ametalk! and as merchandise for the drama adaptation of the manga series
An Incurable Case of Love. == Animated series ==
