This study aims to experimentally evaluate the compression of snow during storage in a deep storage tank. First, small scale experiments related to acceleration of the compression of snow by means of water addition for three hours were carried out. Results showed that the addition of 20 wt% water was suitable. In addition, coefficients of viscosity of the compression for wet snow in a short term compression were evaluated. Next, long term experiments concerned with compression of dry snow for the wide range of snow density were done. When the initial snow density was high, the changes of coefficients of viscosity of compression with snow density were quite different from the previous empirical equation for the natural fallen snow. It was shown that the maximum dry snow densities were limited and each maximum density reached about 562 kg/m^3 independent of the initial density. Coefficient of viscosity of the compression was approximately 9.0 × 10^<11> Pas at this maximum density. A calculation method of coefficient of viscosity of the compression was proposed using this point for the wide range of the initial snow density.
