National Astronomical Observatory of Japan




The National Astronomical Observatory of Japan has been completely reorganized to incorporate the project system in accordance with the rearrangement of the Inter-University Research Institutes on April 1, 2004.

We redefined each research unit as an observatory/center carrying out projects with specific objectives and term. The aims of introducing the project scheme are to specify the research objectives and to attempt further activation.

The introduced project system will advance sharing of resources throughout the entire observatory, define the responsibility and capability of project leaders and staff, and encourage research plans which are abundant in research objectives by improving their clarity and independence.

Acting on the intensions of the project system, we have reformed the center and newly established research divisions.

C Projects

Nine Observatories as Main Driving Force of NAOJ

The C projects group consists of the six observatories and three projects, such as Subaru Telescope, ALMA (NAOJ Chile Observatory), “HINODE” and Nobeyama Radio Observatory, which have been completed as NAOJ facilities and are operating. This project group is the main driving force of NAOJ actively supporting leading edge observations and research.

B Projects

Two Development Projects for NAOJ’s Future

The B projects group includes two project offices that are under construction or being developed. These are expected to undertake NAOJ observations and research in the near future.

A Projects

Four Projects for Next-Generation Astronomy

The A projects group is designed and established to foster pioneering research and development (R&D) activities. This aims to encourage the creativity of researchers and create a diverse and advanced R&D environment. Four project offices, t hat are JASMINE Project Office, the Extrasolar Planet Detection Project Office, the RISE Project, and the SOLAR-C Project Office; are classified into the A project group. Each project has selected an ambitious theme, and is performing the R&D that will open the way to a new era of Astronomy.


Centers Featuring NAOJ

The three Cnters exceed the framework of individual projects and play key roles in equipment development/technological research, the numerical simulations, data analysis, data archiving, and public outreach activities. The Centers simultaneously have characteristics of both projects and basic infrastructures of NAOJ.


Base of NAOJ

The four Research Divisions have been newly set up to secure spontaneous ideas and individual research by each astronomer as well as to enhance the flexibility of our staff. Each researcher working for their project belongs to one of these infrastructures.

Office of International Relations (OIR)

Window to abroad

Office of International Relations is to make the NAOJ a truly international and innovative research center in astronomy.
