Who we are
Clay, hands and heat, kept small on purpose
Blue Windmill is a working pottery in central Tokyo. We throw, trim, glaze and fire in small batches, and we teach the same craft to anyone willing to get their hands dirty.
The beginning
How the studio started
The studio opened with two wheels, one small kiln and a shelf of test tiles. We wanted a place where functional tableware could be made by hand, one piece at a time, and where the people buying a cup could stand in the room it was made in. That first winter we fired more failures than keepers, but the shape of the practice was already clear: slow, repeatable, honest about its mistakes.
Years on, the shelves hold mugs, bowls, plates and vases that leave the studio by the dozen each week. The two wheels have become eight, and the single kiln is now three, but the batch has stayed small on purpose. A run of forty bowls is still a run we can watch from wedging to final glaze.
The making
What happens between clay and shelf
Every piece is either wheel-thrown or hand-built. Nothing is slip-cast, nothing is bought in blank and re-labelled. A mug starts as a weighed ball of stoneware, is centred, opened, pulled and trimmed, then dried slowly before its first bisque firing. Only then does it meet a glaze.
We mix our glazes ourselves in small test batches, logging each recipe against the kiln it was fired in. That is why two mugs from the same shelf can carry the same name and still read slightly differently in the light — the variation is the record of the hand and the fire, not a flaw to be sanded away.
The teaching
Why we run classes at all
A studio that only sells pots is half a studio. We run scheduled workshops for beginners who have never touched a wheel and intermediate makers who want to tighten a form or try a new glaze. Classes are kept to six seats so that every pair of hands gets looked at, and the wheels you learn on are the wheels we work on.
Private sessions and small group bookings are available for those who want to move at their own pace, and studio members get recurring access to work independently between classes once they have found their footing.
The commissions
Making to order for cafes and homes
Alongside the catalog, we take commissioned work. A cafe might need thirty matching pour-over drippers; a home interior might want a single oversized serving platter in a specific glaze. We talk through form, volume, glaze and timeline first, throw a sample, and only scale the run once the sample is approved.
Custom runs are priced per piece with a small sampling fee folded into the first order. Because everything is hand-made, lead times are measured in weeks, not days, and we would rather quote honestly than promise a kiln it cannot deliver.
The standard
What we will not compromise on
Functional ware has to actually function. Our tableware is food-safe, dishwasher-steady and balanced in the hand before it is anything decorative. A handle that is pretty but hot to hold is a handle we throw away. A glaze that crazes in use is a glaze that goes back to the test shelf.
We are equally plain about what we are not. We are not a factory, we do not keep thousands of identical units in a warehouse, and when a batch sells out it is genuinely gone until the next firing. That is the cost of making by hand, and we think it is a fair one.

Where to find us
The studio is open Tuesday to Sunday, 10:00 to 18:00, for pickup, browsing and class check-in. You are welcome to watch a firing cool or ask what is on the drying shelf. If you are planning a visit for a specific piece, a quick call ahead means we can set it aside for you.
