The ACM (Association of Computing Machinery) CHI conference on Human Factors in Computing Systems is the premier international conference of Human-Computer Interaction.

CHI takes place in Yokohama, Japan, at the PACIFICO Yokohama from 26 April to 1 May 2025, while also supporting remote attendance.

The conference embraces the theme of Ikigai, a Japanese concept referring to what gives a person a sense of purpose, a reason for living. Today’s world, people are facing a multitude of challenges in climate change, growing inequality, technological disruption, global conflict, and health crises. Ikigai concerns the ability of a person to find their purpose and balance their agency, their passion, their capabilities, and the impact they can have. The CHI community consists of people with many passions and talents, people from different disciplines and walks of life. In harnessing our ‘Ikigai’ into a communal ‘IkiCHI’ we can be greater than the sum of our efforts and offer unique contributions to solving the difficult challenges ahead.

The cherry blossom or ‘Sakura’ as depicted in the CHI’25 logo signifies a time of renewal and optimism. The conference takes place in the period of cherry blossom growth and in this environment of optimism and renewal, we wish you will find your IkiCHI.
