Historical Approach on Hot Spring Chemistry in JapanRefer to the Persons Belonging the University of Tokyo
Kunihiko WATANUKI+

Abstract
History of spring chemistry is described mainly referring to person belonging TheUniversity of Tokyo from Meiji era. The research is going to qualitative to quantitative
and analysis major component to minor one, including gas and radioactive materials.
The analysis of isotopes such as hydrogen, oxygen and sulfur clarify the source of hotspring water.
