Story

In Sumida, Tokyo, at the foot of Skytree and just across the railway tracks, there is our small factory. What we usually make are metal parts that work inside machines. Once they are built into a finished machine, they are almost never seen. They are never known by name, never put on display.

All that is asked of them is to be exact. Hold the dimensions on the drawing, meet the tolerance asked for, and make something that does its job properly. We have been making things this way for a long time.

There is no need to stand out. Make it properly, even where no one will look. That was ordinary to us.

Then one day the thought came to us. What could we make if we turned this skill to something else entirely? Something freer. Something we actually wanted to make.

Cutting that no one would bother with if efficiency were the point. Time spent until people ask why we go that far. A small factory that has cut machine parts for decades, pouring in everything it knows. A waste of skill, you could call it. But we think the interest of making things lives in exactly that waste.

What we wanted to make was not simply a box for storage. If a box is there to hold something that matters, the box itself may as well be something you want to take care of.

Not a box to keep jewels in, but a box more beautiful than the jewels.

We were sure we could make it. tamatebaco is not a box folded from sheet metal. It is not several parts welded into the shape of a box. It is cut from one large block of metal. We leave only what is needed and cut away everything else.

It takes time. It uses material. There are far easier ways to make a box. We keep cutting anyway, because a single block gives a beauty with no seam in it. And more than that, because it is the way we have always worked.

The box is cut on the machines that cut precision parts every day, and by the same craftsmen. The lid and the body should sit together cleanly. Closed, there should be no play you can feel. In the hand, it should feel like a single piece of metal.

Close the lid. It settles, and a quiet resistance stays in your fingertips. That feel was not staged afterward to look expensive. It is simply what happens when a factory that has faced fractions of a millimeter for decades makes a box. That is all it is. And we think that ordinariness is exactly where the value of tamatebaco lies.

We also kept as much of the metal's own beauty as we could. The body is wrapped in a black that holds the light down. It does not flash. It takes the light quietly. Against it, we left the shine of cut metal.

Light running along the edges. A thin single line where the lid meets the body. Depending on the angle and the way the light falls, that outline changes quietly. There was no need to add much decoration. Lines that appear through cutting. The weight of metal. The beauty of a gap made by precision.

The beauty was already inside the block of metal, waiting to be cut free.

That is how we see it. The name comes from the tamatebako of an old Japanese tale. A box Urashima Taro carried back from the palace beneath the sea. He was told never to open it, and in the end he lifted the lid. White smoke rose, and all the time that had seemed to stand still came rushing back to him.

The box that seemed strange to us as children looks a little different now. What matters is not always what costs the most. Perhaps something becomes precious together with the memory and the time held in it. That thought is where the name came from.

So we have not decided what goes inside. A ring you love. A watch you have worn for years. A necklace, a key, a letter. Something you never show anyone, that is special only to you. One of those. That is what we hope you keep in it.

tamatebaco is not an accessory case for storing things.

It is a place for one thing that matters.

What you keep inside is yours to decide. Made of metal, this box will gather its marks and carry a long stretch of time. Even as what is inside changes, even as the life around it changes. The box may well outlast all of it.

That is why we chose not to make many in a hurry. Cut one, check it. Finish it, check it again. Each one is engraved with its number, and we make only the number we set. Not a box to line up in quantity, but a box for one person to keep for a long time. There are only ever a few.

Sumida, Tokyo. This town has long had people who cut metal, people who hammer it, people who polish it, and small factories that have each supported making things with their own skill. We are one of them.

A small factory that usually makes machine parts no one ever sees. There, again today, a block of metal is set on a machine and cut away little by little by a craftsman's hand. The skill sharpened for years for places no one looks now goes into something that can be seen. Not because anyone asked for it, but because it is what we truly wanted to make.

Not a box to keep jewels in, but a box more beautiful than the jewels.

In a small factory in Sumida, Tokyo, tamatebaco is made.
