A boil-off rate reduction method for a liquefied natural gas (LNG) storage tank. The boil-off rate reduction method for an LNG storage tank comprises: a step of manufacturing an LNG storage tank having primary and secondary insulation layers; a step of connecting one end of a second vacuum hose to the secondary insulation layer; a step of connecting the other end of the second vacuum hose to a vacuum pump; and a step of lowering the internal pressure of the secondary insulation layer by operating the vacuum pump, wherein the inside of the secondary insulation layer is vacuumized to lower the water content percentage of plywood included in the secondary insulation layer.
