I've begun to create a google map of classic okashi-ya in Kyoto whose sweets are iconic for chanoyu. I've now made it accessible by others who can help to document this information in English as well as Japanese. Photos, web and brick-mortar addresses. https://www.google.com/maps/d/edit?mid=zrODjcwtT-p8.kDH44qxhkqGU, etc. are very welcome. Please send me an email to participate in this project. lwdeutsch (at) earth link [dot] net.
Cha-do, the Japanese "Way of Tea", is neither ancient nor exotic, neither sacred nor profane. In fact, it is extremely ordinary, orderly and essential. In practice, it is "simply" making sure you have properly heated the water for the tea, literally cha-no-yu. In its atmosphere of heightened awareness and hospitality, host and guest ultimately transpose roles and unite. It is this very give-and-receive dynamic exchange that makes the world a wonderful place.
