 Designing Future Society for Our Lives The theme “Designing Future Society for Our Lives” makes individuals think how they want to live and how they can maximise their potential. It is also intended to drive co-creation by the international community in designing a sustainable society that supports individuals’ ideas of how they want to live. In other words, the Expo will ask a straightforward question to everyone, “What is the happy way of life?” for the first time. The Expo will correspond to this time when new social challenges, including expanding economic gaps and heightened conflicts, are emerging while science technologies are evolving, including AI and biotechnologies, that will present changes to humankinds, for example, extended life spans. While values and ways of living have become increasingly diversified in recent years, technological innovations enable everyone to access and communicate a hitherto unimaginable amount of information. Fully considering such progress, Expo 2025 Osaka, Kansai, Japan, will feature health, medical, and other advanced initiatives, including carbon neutrality 4 and digitisation, and collect wisdom and the best practices from around the world to provide solutions to various issues with diverse values considered.


To elaborate further on the discussion of ‘life’ as the central piece of the Expo’s theme, three subthemes have been established: Saving Lives, Empowering Lives, and Connecting Lives. Lives referred to herein as part of subthemes cover not only one’s daily life or one’s life span, but also the life as what makes everybody and everything alive. Japanese culture has long been based on the belief that any material, from all living creatures to even a pebble along the road, have an inherent life in them. With this in mind, the Expo welcomes the consideration of ‘life’ not just for human beings but also in a broader sense of diverse creations and nature that surround humans.


Saving Lives:

The subtheme of ‘Saving Lives’ focuses on protecting lives. This subtheme may be associated with more specific keywords, such as countermeasures against infectious diseases through improvement in public health, ensuring safety through disaster readiness and disaster risk reduction initiatives, and harmonious coexistence with nature.

Empowering Lives:

Empowering Lives focuses on enriching the lives of individuals and expanding their potential. Exhibitions on this may include, for example, high quality remote education through the use of ICT; theextension of a healthy life span through appropriate exercise and diet; and the maximisation of human potential through the use of AI and robotics.


Connecting Lives:

The subtheme of ‘Connecting Lives’ focuses on getting everyone engaged, building communities and enriching society. This subtheme may be associated with more specific keywords, for example, the power of partnership and co-creation, advanced communications enabled by ICT, and the design of a data-driven society.



People’s Living Lab

The concept of Expo 2025 Osaka, Kansai, Japan, is “People's Living Lab.” This concept represents the Expo’s approach toward putting its theme into practice and serves as a guideline for projects to be implemented in this Expo to evolve the Expo’s style into a place for more practical actions. It can be said that the most distinctive characteristic of this Expo will be the endeavour to give a realistic picture of a future society not just through thought but also through action. This endeavour will be being begun before the Expo, by inviting diverse participants to come together with various initiatives (such as health and medical initiatives and initiatives concerning carbon neutrality and digitisation) in their respective positions and tackle challenges whose solution will help achieve the SDGs at or outside the Expo venue. Positioning the Expo venue as a laboratory where new technologies and systems will be verified, we will raise it into a huge apparatus that will trigger the creation of innovations by diverse players and apply those innovations to real society.


The site for the Expo is located in Yumeshima, an artificial island located on the waterfront in Osaka that offers visitors a view of the Seto Inland Sea. We will promote the Expo as the one connected to the world through the surrounding sea and sky, as well as providing programmes taking advantage of the venue’s location. With an area of 1.55 km2 , the venue will have a pavilion area in its centre, with waters in its southern part and greenery in its western part.
