What is “Jinenjyo”?


Jinenjyo (Wild Yam) is an indigenous plant of Japan. It is very nutritious because it contains protein, vitamins, and amino acids. It also contains large amount of digestive enzymes, such as amylase, that promote cell reproduction and a healthy metabolism.


Our Jinenjyo grows with plenty of minerals from the mountains and the forest around the field. Clean water and the severe climate ensure our Jinenjyo do not have that typical muddy odor.


Growing wild yams can be difficult. That is why it’s hard to find in the market, and then when you do, it’s too expensive. However, Farm Kazuto developed the know-how to raise wild yams. We can produce and deliver them with a reasonable price because we are a commercial farm.


We also provide a beautiful gift box. You can buy wild yams as a gift to give someone for a healthier life.
