I’m using this today
Looks awfully like a yixing, but is in fact a tokoname pot made by one of the Yamada Jozan (there have been three so far, in good Japanese tradition of passing down the name). I’m not quite sure which generation made this particular one — some indication online seems to suggest the first, but I can be wrong. This type of pot was made basically in imitation of yixing ware, and the Yamadas have been particularly good at it. I got this without the original tomobako, but it comes with a yuzamashi and five cups. I’m only using the pot at the moment, and ignoring the rest. Obviously, this was intended for sencha, but I’m making Chinese tea with this, with good results.
