The Nobeyama Radio Observatory (NRO) is a division of the National Astronomical Observatory of Japan (NAOJ) and consists of three radio instruments located near Minamimaki, Nagano at an elevation of 1350m.

• The 45m Radio Telescope: A 45m single-dish radio telescope that operates in short-millimetre wavelengths. Its receivers operate at 1, 2, 3.75, 9.4, 17, 35, and 80 GHz in both left and right polarizations.
• The Nobeyama Millimetre Array (NMA): An millimetre interferometer consisting of six 10m diameter telescopes.
• The Nobeyama Radioheliograph (NoRH): An array of eighty-four, 80 cm antennas dedicated for solar observations. Its receivers operate at 17–34 GHz in both left and right polarizations.
• The Nobeyama Radio Polarimeters: A set of radio telescopes that continuously observes the full Sun at the frequencies of 1, 2, 3.75, 9.4, 17, 35, and 80 GHz, at left and right circular polarization.
