Drinking sake "Sake Road"
It seems that there was a "sake ceremony" like tea ceremony and flower arrangement, but it is not known now.
It is the essence of trying to unify the spirit through sake, and I hear that there was a very strict manner in how to sprinkle, drink, and distribute sake.
However, if you can't enjoy sake purely, you'll end up with a strict rule, so here, as the minimum "adult manners" to enjoy "My Gui Drink". I would like to propose a new "Sake way".
