is a Japanese physicist and professor at the University of Tokyo best known for having invented the magic wavelength technique for ultra precise optical lattice atomic clocks.^[1] Since 2011, Katori is also Chief Scientist at the Quantum Metrology Lab, RIKEN.^[2]

Recently, Katori's group performed a measurement of gravitational redshift with two transportable strontium optical lattice clocks over nearly the entire height of the Tokyo Skytree, setting a new record for the best ground-based test of general relativity.^{[3] [4]}
