Summary

NAOJ is a research institute for astronomy in Japan. As a base for astronomy in Japan, we conduct various research activities centered around the open use of astronomical observation instruments.

In particular, in recent years, we have strongly promoted the development and operation of large-scale open-use facilities including ALMA and the Subaru Telescope and research utilizing these facilities. We are actively conducting theoretical astronomy using supercomputers. In this way, we contribute to the development of astronomy using both observational and theoretical approaches.
