Recommendation for the Promotion of the International Linear Collider Project

Federation of Diet Members for ILC

The ﬁelds of particle physics and accelerator science, which underpin particle physics, arededicated to exploring the fundamental structure of matter and the universe during itscreation. Japan has made substantial contributions to this ﬁeld over the years, and it iscrucial to continue strengthening our international competitiveness in this area.

The attraction of the International Linear Collider (ILC) Project to Japan stands toestablish Asia's inaugural large-scale international Science and Technology center. Thisendeavor holds the potential to signiﬁcantly enhance Japan's research capabilities andgrowth strategy, positioning the nation as a pivotal Science and Technology powerhouse.
Focusing on this recognition, the Federation of Diet Members for ILC is advocating forthe advancement of next-generation accelerator technology through international
collaboration. This will contribute to the progress of the ILC project, and we appreciate
the achievements made thus far."As the dynamics of power in international relations have undergone signiﬁcant changes
in recent years, there exists a pressing need for reﬁning innovative capabilities withinscience and technology endeavors. This necessitates the strategic and concentrated
allocation of resources to foster advancement. To tackle unexplored challenges with
cutting-edge technology and knowledge, achieving groundbreaking results through largescale projects and establishing advanced experimental facilities by fostering collaboration
among nations that uphold shared universal values is essential. For the ILC, with noexception, it is inevitable to reach a consensus among the international researchcommunity that the project must be realized with international collaborations. Scienceand technology play an important role in contributing to the global peach, and it is hardly
possible for a single country to accomplish a project of this scale alone.

From this perspective, the Federation makes the following recommendations.

1.

The ILC project will be further promoted by the research community, industry,organizations promoting the candidate sites, relevant ministries and agencies, theDiet members and other political organizations within an all-Japan framework.

2.

For the ILC project, international collaboration will be further strengthened as a
global initiative involving the research community. This will be achieved throughclose cooperation between the ILC International Development Team (IDT), aninternational promotion organization established under ICFA, and the domestic
research community.

3.

The Ministry of Education, Culture, Sports, Science and Technology (MEXT) shouldplay an active role in collaborating with the international research community toachieve the global accelerator program. This collaboration should utilize theframework of the Liaison Committee on Future High-Performance Accelerators, inpartnership with the Cabinet Oﬃce, as well as other relevant ministries and agencies.
