A guidance system includes: a device having a first human body communication unit for performing human body communication via a human body; a switch having a second human body communication unit for performing human body communication via the human body; and a controller controlling the device and the switch. The controller obtains device information relating to the device from the first human body communication unit via the human body and the second human body communication unit when the human body contacts both of the first and second human body communication units. The controller provides guidance corresponding to the device information.
