Scandi style
This blog gives quite a nice overview of Scandinvian ceramics that might interest you. Odette, see bottom for some Japanese websites. There is an interesting crossover between Scandi and Asian style.
I stumbled across the blog when trying to find something else that I'm struggling to describe: a type of retro ceramic vase that is folded in a geometric fashion.
I had thought that the term Origami style might come up trumps but it hasn't really. There was a lovely white one on one of the Scandinavian websites that you sent me. Unfortunately, I don't really know which site any more.
