A loading system includes one or more adjusting mechanisms configured to adjust a position of the container held by the container holder, a controller configured to control operation of the one or more adjusting mechanisms, a transfer mechanism configured to move a loadable object into a holding space of the container with the container held by the container holder to transfer the loadable object to the container, and one or more position detectors. The one or more position detectors are located to detect a relative position of a loadable object when the loadable object is held by the transfer mechanism and is in the holding space. The controller is configured to perform an adjusting control in which the position of the container is adjusted to place the container in a proper position with respect to the loadable object, the adjusting control being performed based on detected information from the one or more position detectors, and being performed during at least a portion of a process of transferring the loadable object by the transfer mechanism, and being completed before the loadable object becomes supported by the container.
