In Japan, an event called Tangono Sekku of the Japanese Boy's Festival on May 5 will be held from ancient times. This is a wish for the boy to grow up as a great samurai. Ueda Soko who established Ueda Soko Ryu was a samurai, so members of Ueda Soko Ryu value this traditional event every year even now. At this tea ceremony we provided on tea to about 100 people. In this tea ceremony, I designed a temporary tea room according to the traditional way of continuing from ancient times. In addition, I choiced tea ceremony equipment and was in charge of setting of the tea room and the performance of the tea ceremony etc.
