The results obtained from a survey of balneal treatment and medical researches made mainly by means of the CMI card method at Tamagawa Spa in Akita Prefecture are summarized as follows;
1) The spa visitors were about 540 in number, women being twice as many as men. Classified into age group, the number of visitors was almost equal in each group, and classified into occupations, farmers were the largest in number.
2) The visitors came from nearly all parts of Japan, but the majority of them were from Akita Prefecture: 61.7%. Of all the visitors, 52.1% came either for treatment or for recuperation and 31.9% for recreation.
3) This survey revealed that visitors without diseases were 47.9%. Of those who visited the consulting room, the patients with the circulatory diseases were the largest in number.
4) The occurrence of bathing reaction was observed in 37.9%, and those with dermatitis were 21.2%.
5) Those who drank hot-spring waters were 28.4%.
6) The majority of visitors stayed for one or two weeks, bathing three to four times a day.
7) Only 5.5% of visitors came there under doctor's directions, and 6.8%, of them came having information from newspaper or magazine articles. Most of the visitors came there based on their own experience or on others' recommendation.
8) In the CMI, of 236 visitors, 67 were classified into the 1st group (28.4%), 88 into the 2nd group (37.3%), 56 into the 3rd group (23.7%), and 25 into the 4th group (10.6%). Of 108 controls, 45 were classified into 1st group (41.7%), 43 into the 2nd group (39.8%), 17 into the 3rd group (15.7%) and 3 into the 4th group (2.8%). Thus the 3rd and 4th group were quite large in number among the spa visitors. Very few of the visitors over 60 years of age belonged to the 3rd and 4th group. The number of men and women was almost equal in each group.
9) Those who belonged to the 3rd and 4th group were found in the patients with circulatory diseases more than in those with other diseases.
10) No relation seemed to exsist between the ratio of the body length to weight and CMI classification.
11) Of the visitors, 62.4% had the systolic hypertension and 48.9% diastolic hypertension. No definite relation was observable between blood pressure and CMI classification.
12) Of the visitors, studied by means of the CMI card method, 112 visitors were chosen at random for electrocardiograms, of whom 10 were classified into the abnormal group (8.9%), 38 into the semi-abnormal group (33.9%), and 64 into the normal group (57.2%). Incidence of the 3rd and 4th group was high in the abnormal electrocardiogram group.
The incidence of the 3rd and 4th group is higher in the cases with sinus tachycardia, arrhythmia, abnormal p wave, bundle branch block and severe ST-T change than in the subjects with sinus bradycardia, prolonged P-Q interval, premature beat, left ventricular hypertrophy and slight ST-T change.
13) CMI card method was useful for screening neurosis out of the mass.

The results obtained from a survey of balneal treatment and medical researches made at Hanezawa Spa in Yamagata Prefecture are summarized as follows.
1) Visitors to this spa vary in age, include both sexes in equal number and are, by far, farmers.
2) Visitors are mostly from the local area and surrounding villages and towns, 70% of whom come to the spa for recreation and 20% for therapeutic treatment and recuperation. The figures mentioned here greatly depend upon the time this survey was made, and it is quite probable that the number of visitors for balneal treatment should always be much larger.
3) In this survey, short-time visitors are largest in number, coming to the spa for recreation. Long-time visitors come there for balneal treatment. Visitors are mostly those with diseases of the digestive organs and those with the skin diseases.
4) The larger number of visitors bathe four to five times a day and about 40% of them drink hot-spring waters. Because of the presence of a large number of short-time visitors, the effect of balneal treatment and bathing reaction could not be made clear.
5) Only 4.4% of visitors came there under doctor's directions.
6) Observation of the effect of drinking hot-spring waters on the excretion of gastric juice revealed that it has power to neutralize acid in the stomach and to control the excretion of gastic juice. Such should naturally be the case because this spa is of alkaline muriated spring.
7) With a view to find the effect of drinking hot-spring waters at this spa, examinations were made of renal function. The results obtained from the dilution tests show that the urinary excretion has been delayed and the power of dilution has declined. It is advisable, therefore, that visitors should see whether they are afflicted with the diseases of kidney or circulatory system before they resort to drinking hot-spring waters at this spa.
