Needs to Hot Spring Sciences
Yukiko SAKAI+

Abstract
Usage of hot spring resources is a prerequisite for the progress of the hot springsciences, which in return should be able to resolve problems caused by this perpetual useof hot spring water. The author takes up two problems as such examples : one emerged
as the lawsuits on the terms and conditions of a bore hole drilling for a hot spring well,
the other is brought by the e%uent regulation of speciﬁc materials contained in hotspring water. In order to ﬁnd a resolution of these issues, legal or chemical, knowledge ofthe hot spring sciences is indispensable.
Key words : Hot spring science, Drilling, E%uent regulationῒῑ !"#$%
