Tea started to spread outside of the Uji district where it had mainly been grown since the beginning. But by now popularity and so demand was growing rapidly and called for plantations all around Japan. The samurai class, who loved everything about the Sung dynasty including the Tea ceremony, embraced it wholly and caused even greater popularity of the ritual preparation of green tea.
In 1333, the Kamakura shogunate fell which led to civil wars in the whole country. A new class of people came into existence, the Gekokujou (parvenus). These nobles whose extravagant lifestyles attracted much attention from the public, often held tea parties for their friends called Toucha. In this game the guests were tested on their abilities to distinguish between Honcha (genuine tea) and other tea. Soon betting accompanied these games and great valuable prices were presented to winners which added to the excitement of the game.
Originally the guests were given ten cups of tea, but this number increases to twenty, thirty and eventually one hundred cups per person. If there was a great number of people attending the party, it would have been impossible to provide every guest with one hundred cups. Although followed procedures are unknown, the guests probably passed cups from one the next. This technique of passing around tea bowl probably explains why only one tea bowl is used during today’s Tea Ceremony.
However strange this habit of sharing might seem to us now, it probably has its roots in the Samurai class. The Samurai had strong family ties, and when the family would gather on important occasions, it was custom for the lord to take the first sip of Sake from a large cup and then pass it among his retainers as a reaffirmation of their close bonds.
