“From our own Tea Garden until our own Factory”

“Kodawari” without using Chemical

About 20 years ago, Yasuhisa Horiguchi noticed that using chemicals kill not only pest but also some natural part. He was struggling to find a way to grow tea wihout using chemical everyday. One day, after a big typhoon, he realized that all the pest have diseappered blown away by the wind. With that hint, he started to develop a machine focused on wind and water pressure. From that time no matter if it was day or night, he immersed himself into steady study, forgetting sometimes food and drink. When he was almost feeling on the point to give up, the smile of customers encouraged him. Almost years later, after failure and failures, he finally succeed; the sprinkling/strong wind prevention machine “Hurikane King” was born. This machine respect the ecosystem of nature in our tea garden and allow us provide a tea that doesn’t need chemicals against pest. Today, It still protect our tea garden. There is even now a new machine call “Steam Buster SL” that use hot water with high pressure to prevent the weed from growing. In , all those effort make us abble to acquired the FSSC which is a world food safety standard. We have this certification from our ownTea garden until our own factory. We deeply blieve that :“Good for nature is good for human”.
