To compare the colliders between China and Japan from the perspectives of historical development and running performance and to learn the development experience of Japan and provide references for future technological layout, especially for large research infrastructure planning, this study discovers that the parameters of Chinese collider, which was constructed earlier, are limited by funding, technology, and other factors. Its research field is charm physics, whose energy range is lower than that of B physics. Whereas Japan, which has a foundation in engineering technology, targets at the B physics with richer physics prospects. Both colliders have obtained significant scientific achievements. Japan is more prominent in the research output and the degree of international cooperation is higher. The output of Chinese collider has increased significantly in recent years, and China keeps leading in the research of charm physics.
