I got an email a few weeks back from the Zencha website announcing some of Noutomi Susumu's new work. I bought one piece, which I didn't realize was large enough to use as a cereal bowl.
Once I got it (I still like it even though it's huge), I ordered a smaller one, which hasn't arrived yet. It all works out in the end, though, because I now have several tea-ware items from him of varying sizes that all match! I'm glad I went back to look because they sold out fast.
If you go to their site and sign up for their newsletter, you will be notified of new tea-ware before it's available to everyone else.
