We have investigated a prototype of kaonic nuclei, "$K^-pp$", with acoupled-channel Complex Scaling Method (ccCSM). Combining the ccCSM withFeshbach projection method, we can handle a coupled-channel problem effectivelyas a single-channel problem. By using an energy-dependent chiral SU(3)-based$\bar{K}N$ potential, the $K^-pp$ ($J^\pi=0^-$ and $T=1/2$) is obtained to beshallowly bound with the binding energy of 20-30 MeV. The mesonic decay widthdepends on the interaction parameters and ansatz; the decay width is rangingfrom 20 to 65 MeV. In case of $J^\pi=1^-$ state, no three-body $\bar{K}NN$resonant states are found.
