Why do the Japanese have the longest life expectancy in the world? The secret lies in their land and culture! Japan’s land is made up of deep-sea crustal land. This natural gift continually provides an abundance of minerals and trace elements through their daily lives. Japanese people enjoy the therapeutic effects of hot springs, and they also cultivate various fruits and vegetables in greenhouses heated by hot spring energy, producing some of the world’s highest-quality crops, including the world’s most expensive fruits.
