I attended the interesting event which was to promote Japanese green tea from Shizuoka (静岡). There, a doctor works for a hospital in Kakegawa-city (掛川市), Shizuoka prefecture, presented observation by him and colleague doctors in the city and he implied cause-effect between intake green tea and wellness.
Shizuoka prefecture reported the result of radioactivity test on tea. It shows there is no negative health influence on consumption of tea from Shizuoka.
