The Isshinryu punch looks very much like the punch shown in the photo of the old-time bare-knuckle boxer. Fist is vertical, thumb is on top, not along the side. We strike with the top two knuckles. Hand, wrist, and arm are in alignment. I can hit quite hard without conditioning my hands and without hurting my knuckles, wrist, etc. The pressing down on the thumb moves the bones of the hand into correct alignment. IMHO.
Oh it can absolutely hit hard. I do the conditioning for the fist (and palm since I prefer palm strikes) more to minimize injury to myself. I have seen more than a few of my co-workers get hurt even punching correctly but say the "bad guy" zigs instead of zags and a punch that was headed to the cheek ends up connecting with the forehead or did horizontal fist punches (especially round punches) and the wrist alignment is a tad off and they end up getting a sprain/strain. If not for having seen hands swollen two sizes bigger or wrists in braces I may not be doing the conditioning, but on the downhill side towards retirement I am very much about mitigating the risk of injury. I also make sure I stretch everyday before work (especially when it's cold out) with the same idea in mind.
Nothing is perfect though there is still the risk of injury, it's just about mitigating said risk.
