Disclosed is a technique whereby when multi-component liquefied gases such as liquefied natural gases (LNG), liquefied petroleum gases (LPG) or the like which are different in composition, density or the like are stored in the same storage tank, any stratification of the liquefied gases within the storage tank is prevented. The introduction of the liquefied gas into the storage tank is accomplished in such a manner that the introduced gas enters the storage tank in the form of a jet of liquefied gas which is shoot out from near the tank bottom obliquely upwardly with an ascending vertical angle in a predetermined range and reaches or comes near to the free surface within the storage tank, and in this way the desired mixing of the introduced liquefied gas with the liquefied gas previously existing in the storage tank is effected as soon as the introduced liquefied gas enters the tank.
