Having obtained this recently – I’m still trying to make sense of all the parts. So far, identified objects are: chataku (2), dishes (2), metal tea scoop, dry leaves presentation vessel (I think – the red/black thing), watercolour painting booklet, signed Baishi laoren 白石老人. Can’t tell if that’s real or not. For the bottom section: 5 yixing cups in bamboo holding them together, 5 small wooden chataku (are they supposed to be used on top of the metal ones?), 5 leaf-shaped dishes, 1 shiboridashi, 1 chaire, made with pewter and missing the original lid (with a replacement wood lid instead) and what looks like an incense burner of some sort (bottom right). Not shown here is a dried lotus that’s extremely fragrant.
I’m trying to figure out how one should be using this for tea. The parts that are easily identifiable are good enough. The rest I presume are for incense burning and also for snacks. One would also have to carry some sort of kettle and a stove. Having a tea picnic is not easy.
