This site is called 用と美 — yō to bi, use and beauty. Yanagi Muneyoshi (Sōetsu) set the two down side by side and bound to each other: use gives rise to beauty, and beauty helps the use in return; where they come apart, he held, a thing turns ugly.
There is a near phrase, 用の美 — yō no bi, the beauty of use. It is likely the one most people meet first, and it has carried his thought to a great many readers over the years. Turning through his own pages, the phrase that appears is 用と美. One kana apart, and a good deal of the meaning sits in that one character.
The の makes one the source of the other: use first, beauty as what comes of it. The と settles nothing. It sets the two down and leaves what passes between them to be seen. That passage back and forth is what he wrote about.
We write about those things as tools: where a thing is used, how it is held, how it is washed, how it changes with use. Alongside the tools of everyday Japan we write about everyday things from elsewhere — Korean ceramics, English slipware — because Yanagi looked at those with the same eye.
What is here comes from things we have used ourselves, or from sources we have checked. Names of kilns, makers, shops and regions appear only where a source can be found for them, and articles carry their sources.
Nothing here is set against anything else. Yanagi's advice was to look before knowing, and we take that as a way of showing a thing rather than a way of arguing about it. The looking is left to you.
The name is written YŌTOBI here, and yotobi where it has to be typed.
