(B) is the preferred way.

Financial stability and security, sharing of cost, human resources and responsibilities, desired openness for the scientific opportunity.

For Japan, hosting such laboratory would be very attractive and in accordance with its national plan for science and technology (S&T basic low, S&T basic plan).

Pre-GLCCPre-GLCC• A realistic way towards the GLCC (Global Linear Collider Center).

• Similar to the existing collaborations for high energy physics experiments.

• The foundation is based on MoU among laboratories and universities.

• Building up the co-working spirit by actual R&D works and designing works.

• Multi-international centers (like ITER) might be a realistic way to start with.

organization of ITER must be carefully investigated.As far as the structure of the international organization is concerned, we can learn from CERN and ITER. The international project must be stable, otherwise it will

cause a fatal damage to the scientific community. We must learn from the case of the SSC project. It is very dangerous if the major decisions are given
