MAXI has been observing all X-ray sky from the ISS for more than 10 years. Until the end of 2019, MAXI discovered 13 galactic black hole candidates,13 (or 12) neutron star binaies, 1 white dwarf binary and 2 (or 3) unidentified X-ray transients. The 13 black holes candidates show various brightness and spectral evolution, which enable us to constrain the masses and distances of the sources. The neutron star binaies discovered include a variety of low-mass and high-mass X-ray binaies:X-ray bursters, e.g., J1647-227 and J1621-501, a "very faint X-ray transient" J1957+032, a possible "Supergiant Fast X-ray Transient" J1932+091, and a 507 sec pulsar J1409-619. J0158-744 is thought to be the first detection of the ignition phase of the white dwarf nova. We also note that some these transeints MAXI discovered are located at high galactic latitudes, which gives a new insight of the binary population and the evolution theory. I review X-ray properties of the X-ray novae MAXI discovered and statistical study using MAXI GSC data.
