In a farm village of paddy field single crop area in Tohoku region of Japan, blood pressure of villagers was measured 3 times, in 1957, 1963 and 1967. Three hundred and twenty of 2452 subjects who were 30 years or over in 1957 were died through those 10 years. Mean blood pressure in 1957 was compared by cause of deaths. By deaths from cerebrovascular disease, which is the dominant cause of deaths, the blood pressure level was higher than the control survival group in both systolic and diastolic, though the difference was not recognized in the age group of under 40 and over 69 years. By deaths from heart diseases only systolic was higher, and by deaths from cancer and other causes the difference of blood pressure was scarcely recognized. Blond pressure changes not only through 10 years but also through 6 or 4 years interval showed a significant tendency that the higher the blood pressure measured in the former time the more dropped the blood pressure in the later time. The tendency is contrary to that found in South Wales by Miall and Lovell. The reason why such blocd pressure change has happened, is elucidated by the fact that most persons who were declared high blood pressure at the first time examination voluntarily received practitioners' medical treatment. Relation between the first time blood pressure and cardiovascular disorders found in the later examination was significant in retinograph rather than in electrocardiogram.
