 note = {From the conservation point of view, one of the main problems in the shelter for Hinooka Tumulus is condensation on the ceiling and walls especially in winter.In order to understand the mechanism of the formation of condensation and to consider countermeasures to prevent it, the thermal environment inside the shelter was investigated by on-site measurements and calculations using a simulation program, NETS.
 From the on-site measurements, it was found that the relative humidity inside the shelter is almost 100% throughout the year. During the night, particularly in winter, the temperature on the surface of the ceiling and walls drops rapidly and becomes lower than the dew point, resulting in the formation of condensation. The result of calculation obtained by NETS reproduced the measurement result reasonably well.
 Assuming that 10cm of soil is stacked on the roof of the shelter, the thermal environment was recalculated by using NETS. As a result, the calculation predicted that the variation of temperature on the surface of the ceiling would be moderated because thermal insulation was increased.This analysis result indicates the possibility of reducing condensation by supplementing materials on the roof.},
