In today's world of consumer-based activities over internet and mobile networks, people's tastes and behaviors are very diverse and have evolved with innovative services and sudden life changes. Furthering data-driven research to better understand consumer-based activities is becoming more important. Under the vision "Automation, Better than Human", we will contribute to creating a better society by promoting the use of AI technology and a deeper understanding of consumer behavior. We believe that the collection of consumer-based data at our company, which includes many platform businesses, is an asset that can provide a social good.

In academia, data-driven research is being carried out. While research has evolved with the advent of computing technology and AI, there are few opportunities to engage with consumer-related data. We hope to address this problem with Rakuten Data Release where researchers can feel "empowered”, and results can be shared with society.
