During the sixteenth century, Sen no Rikyu had a profound influence on chanoyu, the Japanese "Way of Tea", particularly the tradition of wabi-cha. He emphasized several key aspects of the ceremony, including rustic simplicity, directness of approach and honesty of self. An indispensable part of the tea ceremony were tiny wood picks (toothpicks) that were made from the kuromoji tree. The picks can be used to pick foods as well as toothpicks. The picks were made in Kawachigano city because of its abundance of Kuromoji trees. The Hyotan Store from Kawachigano continues the tradition and makes these special picks.
