The present invention eliminates a temperature difference of a storage container that occurs when a low-temperature liquefied gas is loaded, and prevents distortion and deformation of the storage tank and a rollover phenomenon. A storage system 10A includes an LNG inboard tank 12 for storing LNG, a supply system 41 for supplying LNG to the LNG inboard tank 12, and a light extending in a height direction on a wall surface of the LNG inboard tank 12. The fiber cable 24, the laser pulse transmitter 28 for transmitting a laser pulse to the optical fiber cable 24, and the backscattered light scattered from the optical fiber cable 24 are input, and the LNG stored in the LNG inboard tank 12 from the backscattered light. And a management device 23A for managing the storage state of the LNG in the LNG inboard tank 12 based on the temperature distribution of the LNG obtained by the measurement device 30.
