Planet formation with pebbles has been proposed to solve some of the long-standing issues of the classical planet formation model—- the mechanism of planetesimal formation and the timescale of forming a large enough core for the gas accretion. A few groups have performed sophisticated simulations and confirmed the efficiency of pebble accretion in forming various types of planets. However, these studies have not shown whether the pebble accretion scenario can reproduce the observed statistical properties of exoplanetary systems, mainly because such simulations are computationally expensive. We have overcome this problem by adopting the analytical pebble accretion model by Ida et al. (2016) that agrees well with detailed dust growth simulations. We have performed the global simulations of planet formation via pebble accretion, and compared the resulting systems with observations. In this talk, I will present our recent results and discuss their implications.
