Japanese Tea Ceremonies (and other artistic peculiarities)

[Mailanka]

I can't decide how one should represent a skilled practitioner of Chado. This is actually rather relevant for my up and coming campaign, which makes it troublesome.

Once upon a time, back in 3e, the Tea Ceremony had its own skill (a Mental/Hard one). Thus, I suppose one could represent it as an Expert Skill (also Mental/Hard), but 3e did all kinds of wonky things and I see no reason to take it as gospel. A tea ceremony could just as easily be a Professional Skill or a Hobby Skill (and the last seems most likely: While a tea ceremony is surely a complex affair, it doesn't seem particularly difficult to master. Perhaps I'm wrong). Or perhaps its covered under some other skill (it seems to be a performance, but Performance covers stage performances).

On the other hand, it seems the sort of thing already covered by Savoir-Faire or Carousing, perhaps as an optional specialization or a technique. After all, a well-raised samurai woman would know how to properly serve tea as a matter of course! I'm not sure it would even need its own skill.

There's actually quite a few Japanese arts that have a devout following, but I'm not entirely sure how to represent them, like grooming bonsai trees (gardening specialization?) and... doubtless others, but what they are has slipped my mind, as I'm very tired.
