As reported by Aviation Week on 4 October 1982, Japan is conducting an evaluation study on the development of a small space shuttle and has also made this study an integral part of the ongoing study on the future planning of the Japan Space Development Corporation . The representatives of Japan who recently attended the IAF Congress confirmed that their research on the small space shuttle is still at an early stage of conceptual research.
