A liquefied hydrogen tank includes: an inner tank storing liquefied hydrogen; an outer tank surrounding the inner tank; an outer shell surrounding the outer tank; a first heat insulating layer located in a first region between the inner tank and the outer tank; and a second heat insulating layer located in a second region between the outer tank and the outer shell. The first region is filled with a first gas that is a hydrogen gas or a helium gas. The first region has substantially atmospheric pressure or is in a low vacuum state. The second region is filled with a second gas including at least one of an inactive gas or dry air. With the liquefied hydrogen stored in the inner tank, a temperature of the outer tank is a predetermined outer tank control temperature that is higher than a condensation point of oxygen and not more than an atmospheric temperature.
