The detection of gravitational waves will reveal new aspects of the Universe.

The GW Project Office is undertaking the KAGRA project together with ICRR, KEK, and other institutes. KAGRA is a large cryogenic gravitational wave antenna using a 3-km laser interferometer underground at the Kamioka site. TAMA300, a 300-m laser interferometer situated on the Mitaka campus, is a precursor to KAGRA and acts as a test facility to evaluate key elements and techniques before use in KAGRA. We are also designing the space-based DECi-hertz Interferometer Gravitational wave Observatory (DECIGO) in anticipation of future deployment.

• KAGRA

  

  NAOJ is responsible for several key parts of the KAGRA project.

• Advanced R&D

  

  We are developing new technologies to further improve the sensitivity of future detectors.

• Multi-messenger astronomy

  

  Collaboration with other observation channels will give us deeper insight into gravitational wave events.

• TAMA300

  

  We have a 300-m long prototype gravitational wave detector in the Mitaka campus.

• DECIGO

  

  A future project to construct a gravitational wave detector in space.
