The WiLL brand was a marketing approach shared by a small group of Japanese companies who decided to offer products and services that focused on a younger demographic from August 1999 until July 2004 in Japan. The companies that participated were the Kao Corporation, Toyota, Asahi Breweries, Panasonic, Kinki Nippon Tourist Company, Ltd, Ezaki Glico Candy, and Kokuyo Co., Ltd.. Toyota also engaged in a similar "youth oriented" approach in North America, with the Project Genesis program. This selective marketing experiment reflected a Japanese engineering philosophy called Kansei engineering, which was used by other Japanese companies. All products were listed online at "willshop.com".

Scion was a marque of Toyota that debuted in 2003 and was available only in the United States and Canada. The marque was intended to appeal to younger customers, the Scion brand emphasized inexpensive, stylish, and distinctive sport compact vehicles, and used a simplified "pure price" sales concept that eschewed traditional trim levels and dealer haggling; each vehicle was offered in a single trim with a non-negotiable base price, while a range of dealer-installed options was offered to buyers for personalizing their vehicles. The Scion name, meaning the descendant of a family or heir, refers both to the brand's cars and their owners. In an effort to target millennials, Scion primarily relied on guerrilla and viral marketing techniques.
