Chemical and isotopic data are summarized for fluids from newly drilled wells in the Sumikawa geothermal system, northern Honshu, Japan, and the geochemical characteristics of the reservoir are discussed. The fluids are mainly of the Na-Cl type with a near neutral pH, and measured temperatures in wells often exceed 300°C. The total dissolved salt concentration is low (
