There is a stat that is announced by the Japanese government that shows the mortality rate due to cancer by towns and cities (with population over 100 thousand people). Of the top 15 cities that has the lowest mortality rate of cancer, 7 cities are known as a tea production area:
- Fujieda, Shizuoka Prefecture
– Hannda, Shizuoka Prefecture
– Hamamatsu, Shizuoka Prefecture
– Tokorozawa, Saitama Prefecture
– Kagoshima, Kagoshima Prefecture

Of the seven, of course Shizuoka Prefecture will be in there the most with 3 cities.

There are still on going experiments in Japan that looks into the health benefits of green tea. We will update again if any interesting results are announced.
