Proceedings for the KAGRA status talk at TAUP2017, Laurentian University, Sudbury, July 26, 2017.

KAGRA is the first km-class interferometric gravitational wave telescope constructed underground to reduce seismic noise, and the first telescope to use cryogenic cooling of test masses to reduce thermal noise. The construction of the infrastructure to house the interferometer in the tunnel, and the initial phase operation of the interferometer with a simple 3-km Michelson configuration have been completed. The first cryogenic operation is expected in 2018, and the observing runs with a full interferometer are expected in 2020s. The basic interferometer configuration and the current status of KAGRA are described.
