Japanese people have longest life expectancy and it is said that one of the reason can be the foods/drinks they consume.
Shizuoka prefecture is known for No.1 place for green tea in terms of producing amount, growing space and consuming amount.
According to Kakegawa city website, Kakegawa City known for Kakegawa-cha in Shizuoka has lowest death late for cancer all over Japan.
Other Shizuoka cities are ranked within top 10 for less death ratio from Cancer.
In recent years, research on the health benefits of green tea has been conducted both in Japan and overseas, and the hidden health power of green tea has been revealed one after another. In May 2015, the National Cancer Center published the results of a study showing that drinking green tea reduces the risk of death and leads to longevity, which was widely covered by the media (Ann Epidemiol.;25,512-518,2015).
In the results of this study, about 90,000 men and women aged 40-69 (residents of a wide range of regions from Akita to Okinawa prefectures, Japan) who did not have cancer or cardiovascular disease in the first place were followed for about 19 years. As a result, it was found that the mortality rate decreased as the amount of green tea consumed increased, when compared to those who drank less than one cup of green tea per day.
Furthermore, by cause of death, there was no significant association between the risk of death from cancer in either sex, but the risk of heart disease, cerebrovascular disease, and respiratory disease decreased significantly with higher consumption of green tea.
