In the world of JoJo, where spiritual power exists, there is "Fortune Currents" on the battlefields. Joseph Joestar has a talent for feeling this currents on the battlefield, and can manage the currents to his advantage. Furthermore, as a result of managing the currents, if "Fortune Currents" becomes "Destiny", he can foretell what the opponent will say next.
In the world of JoJo, where spiritual power exists, a creatures's shadow has a very weak spiritual power of the owner of the shadow. One of Pillar Men, Wamuu, is able to perceive the state of the spiritual power that dwells in his shadow, and therefore can feel that his shadow has been stepped on.
Hell Climb Pillar, a ordeal to climb a oil-flowing pillar, is very similar to one of the Chinese legends, "Longmen". According to this legend, a carp that have swims up a waterfall called "Longmen" will transform into a dragon. Likewise, those who have climb up Hell Climb Pillar undergo a spiritual transformation of their bodies, obtaining the power to fight Pillar Men.
Prosthetic hands in our world are not yet at the level where they can move like real hands, but in JoJo world, a prosthetic hand that Joseph wears from the end of Part 2 make it possible. This is achieved with the same technology as the Mechanized Soldier Stroheim, a technology that neurally connects the spiritual body that dwells in humans to the mechanical body.
