We review the recent results of the exoplanet search via gravitational microlensing. The microlensing technique is unique and complementary to other methods because it does not rely on the light from the primary. Microlensing is sensitive to small-size planets down to those of Earth mass around dim M-dwarfs. Planets with large semi-major axes more distant than the snow line can also be detected instantaneously without waiting for one orbital period to elapse. Most significantly, distant planetary systems as far as out as the galactic bulge can be probed, which helps us understand the galactic distribution of the planetary systems. We present the current status of the observations focusing on the survey by Microlensing Observation in Astrophysics (MOA) collaboration and summarize the features of the detected planetary systems.
