In cooperation with NSF, this program provides funding for international joint research carried between excellent researchers in Japanese universities and institutes and their US counterparts. The program implements joint research projects on issues difficult to solve by one country alone. In carrying out the joint projects, a synergistic effect is sought by such means as sharing resources and research facilities.

Applicants must hold a full‐time or equivalent position as a researcher at a university or research institute in Japan. However, there are cases when a researcher not employed in a full time position may be eligible. Such persons must be eligible to apply for a Grants‐in‐Aid for Scientific Research ‐ KAKENHI and his/her affiliated institution must judge them able to implement the project and to provide an appropriate research environment (e.g., laboratory, equipment, personnel) for it.
