The founder of tea ceremony Sen no Rikyu stated that tea ceremony can be explained by this simple phrase: ichi go ichi e : one time – one meeting.
The purpose of tea ceremony is not to drink best tasting tea, it is all about enjoying the moment and remembering that this very moment will never come back again. If you want to reserve a tea ceremony session in Kyoto, Tokyo, Osaka or Kobe you can do it here Tea ceremony is quite similar to meditation. When we are participating in the ceremony we have to forget about everything and just focus on drinking tea in harmony.
Building on this philosophy, Rikyu introduced the 4 main principles of tea ceremony: WA, KE, SEI and JAKU (harmony, respect, purity and tranquility).
