2. 2
IMI2 is a Government Interoperability Framework to realize a
society where data can be smoothly harnessed and connected.
We have been working on a government interoperability
framework named IMI since 2011
We are moving forward with our government interoperability
framework project under the new name IMI2, as we move toward
2030, a data-driven society.
２ 意味(IMI)
IMI means semantics in Japanese.

7. • IMI2 is essential infrastructure for data-driven society.
• All services, including AI and mobility services, will be based
on this infrastructure.
Role of IMI2
7
Reduction of design cost and time
Ease of integration and scalability
Improvement of user experience
IMI2
Lower design and operating costs and time
because it utilizes a reference model
Utilizes a reference model, making it easier to
collaborate with other organizations and
leverage existing applications
Improve the convenience of services by
redirecting the design effort to service
enhancement one.

• Service data models are created by derivation of a common
model. So, data linkage is easy even across fields.
