We published a CD-ROM "Geothermal Gradient and Heat Flow Data in and around Japan" (Tanaka et al., 2004a), which includes values of heat flow and geothermal gradient data. This compilation was intended to improve the understanding of variations in the thermal regime in and around Japan. Our current knowledge of the heat flow distribution can be increased by including information derived from geothermal gradient data contained in this compilation. In southern Kyushu, the pattern of heat flow is significantly modified by incorporation of estimates of heat flow from geothermal gradient data.
Key words: Heat flow, geothermal gradient, compilation, thermal regime, Japan.
