among other things, we collect "wintertime" Japanese tea sets. These are usually created as sets of three "cups", and the wintertime tea bowls are usually more closed than the summertime bowls. My father strated this when he was, after WWII, stationed near Kobe where he was aiding in setting up food distribution centers and occupation billets. He was given a set of Meji and he then started to buy others (just tea sets). When Mrs F and I were in Kobe (I was supposed to be working) we met some potters and were explained how the tea bowls and sets are designed for the seasons (open bowls for summer and fall, and closed bowls to keep in the heat, for winter and spring).
So , we built on dads collection fter he passed and I built a vry simple thin walnut cabinet with beveled glass doors to hold the collection). We really should sell em or give em to the kid.
The number three was always considered better luck in Japanese tea serving sets. ( I didnt mention the little pots which were usually pottery AND iron)
