To observe the cyclotron resonance (CR) in Yb4As3, we have performed the microwave experiments with the cavity perturbation and the simple transmission techniques. The CR mass is evaluated as 0.72 m0 which is consistent with the theoretical value of about 0.7 m0 obtained by the recent band structure calculations for LuYb3As3. It can be concluded that the observed CR originates from the light 4p-holes of As ions centered at the Γ point.
