The aim of this paper is to provide a deeper understanding of Shikake through the lens of marketing. "The aim of marketing is to make selling superfluous" is a famous quote by Peter Drucker. Its key message is that marketing is not an effort to control or force consumers to purchase products or services, but an activity to create a situation where consumers engage in consumer behavior spontaneously. The core essence of Shikakeology is a spontaneous behavior change, and it is fair to assume that marketing and Shikakeology share a fundamental philosophy. This paper defines the key concepts in the intersection of marketing and Shikakeology and attempts to classify Shikakes in the field of marketing in accordance with participants' motivation and consciousness. Different types of consumer participation are described in case studies. Finally, attempts are made to reveal the key to success of a Shikake in the field of marketing and discuss future research opportunities.
