Keep it simple, get a OEM front license plate bracket, Japan basically requires front license plates so having a front license plate does little to diminish how the car looks. If you really want no drill, compare a US and a JP Avalon and see if the JP version comes a hole for a screw in tow hook. If it does, all you gotta do is replace the front bumper cover, the front bumper reinforcement, and maybe the front bumper energy absorber then you can use a screw in license plate mount.
