Backward-angle photoproductions of $\pi ^{0}$, $\eta$, $\eta$', and $\omega$ mesons have been measured in the photon energy range from 1.5 GeV to 2.4 GeV at the SPring-8/LEPS facility. Differential cross sections and photon beam asymmetries have been obtained. The cross section data show the bump structures around 2.1 GeV. The photon beam asymmetries for $\pi ^{0}$ photoproduction show a strong angular dependence. The data will be discussed connecting with baryon resonances. In addition, the future plan of experiments with photon energies up to 3 GeV will be introduced.
