The purpose of the present invention is to enable a mixed gas, which is generated when a peripheral part of a loading arm is purged with an inert gas, to be collected without being expelled into the atmosphere and to enable a hydrogen gas, which is extracted when liquefied hydrogen is charged into a liquefied hydrogen storage tank on a liquefied hydrogen carrying vessel or on the shore, to be collected with no change in the high purity thereof. Provided is a liquefied hydrogen transferring system (1) that transfers liquefied hydrogen between a first tank (2) on the shore and a second tank (3) on a liquefied hydrogen carrying vessel. The liquefied hydrogen transferring system (1) comprises: a first transferring means (4) that can transfer liquefied hydrogen between the first tank (2) and the second tank (3) via a loading arm (4a); a second transferring means (5) that can transfer a hydrogen gas to the second tank (3) or from the second tank (3) via a loading arm (5a); inert gas supplying means (7A, 7B) that can supply an inert gas to the second tank (3) when the second tank (3) is empty; and a third transferring means (6) that can collect a mixed gas made up of the inert gas supplied from the inert gas supplying means (7A, 7B) and the hydrogen gas remaining inside the second tank (3) and transfer the mixed gas to the shore.
