Unit tanks (10), which can be connected to each other and which can individually store low-temperature liquefied gas, are formed at a factory separated from the construction site, the unit tanks (10) are transported to the construction site, the unit tanks (10) are connected together at the construction site to form an inner tank (2), and an outer tank (3) is formed around the inner tank (2).
