Medical Anthropological Discussion on the Speciﬁc
Pattern of Mineral Water Drinking in Tsukano-Spa

Abstract
The purpose of this study is to investigate a pattern of mineral water drinking inTsukano-spa, Oita prefecture, and to discuss medical anthropologically on its results.
Qualitative research methods, such as participant observation and interview were conduced for eight days in Tsukano-spa. The speciﬁc pattern of drinking large amount ofwater (+,/**ῌ-,/** ml in a few hours) at midnight was established among users of the spa.
The way of drinking always induced rapid and severe diarrhea. The users believed that“shukuben” (long-time glued stercus in the bowel) was the real reason of various gastrointestinal diseases, and that removing it by drinking the water could make them recoverfrom those and promote their general health. It was seemed that “shukuben” was a
symbol of harmful things for their health, and that the speciﬁc pattern of drinking was anecessary ceremony to remove it. We concluded that they could get healing through the
body image and the process of signiﬁcation, which ﬁrmly inﬂuenced on human illness orhealth seeking behavior. It was expected that there was also such a cultural andcognitive mechanism as in other traditional spas in Japan, and that qualitative researchmethods could be beneﬁcial to clarify such holistic e#ectiveness of spa-therapy.
