[The epidemic situation and intervention countermeasures of stroke in Japan].

From 1951 to 1980, stroke was the main cause of disability and death among middle-aged and elderly residents in Japan. Its mortality once stood in the first place among all the developed countries, with the mortality of hemorrhagic stroke significantly higher than that of the western countries. In 1965, the mortality of stroke in Japan reached a peak of 175.8 per 100 000. Since then, it began to decline rapidly with a range of 5%-7%, and dropped to 139.5 per 100 000 in 1980, and from the top cause of death to the third place. By 2010, the mortality had dropped to 97.7 per 100 000. The significant decline in stroke morbidity and mortality in Japan is mainly attributed to controlling important risk factors and the public health service system's improvement. Setting up related policies and regulations to ensure comprehensive interventions and using the existing monitoring systems and surveys to assess interventions' effectiveness also contributes. Given the similarities of epidemiological characteristics and risk factors on stroke in Japan and China, strategies and measures adopted in Japan will have certain positive significance for China.
