Tsubame City in Niigata prefecture is a metalworker’s town. Blessed with both raw materials and tools since long ago, the metalsmithing techniques that developed here are now known worldwide. One beautiful local craft that has made a name for itself not just within Japan but also overseas is the hammered copperware called tsuikidoki. This two hundred year-old technique of pounding flat copper sheets into three dimensional goods such as kettles and teapots has been elevated to a fine art.

Gyokusendo was founded in 1816. Their efforts to attract overseas clients with a striking balance of traditional techniques and modern design has resulted in an avalanche of interest. Tsubame’s metalworkers produced the original Japanese nail during the early years of the Edo period. There’s a copper mine nearby called Yahikoyama, and good quality copper was mined there. Tsubame became a production area for copper goods because it was so well-placed. They say the method for making tsuikidoki (hammered copperware) was taught to the founder of Gyokusendo, Kakubei Tamagawa, by a travelling craftsman from Sendai.
Short on the process:
a wooden mallet to pound a copper sheet into a circular shape. The copper sheet is just 1.2 millimeters thick. After that, we place the copper over a tool called a toriguchi which is a sort of metal bar, and move the copper ever so slightly after each strike with a metal hammer. This technique causes the copper to shrink, and a vessel shape can be made. The hard copper is heated in a furnace until it softens, making it easier to form. This annealing process is repeated many times during the forming of a single piece. This annealing process is repeated many times during the forming of a single piece. method of coloring the metal can be manipulated to create a wide variety of colors. The mix of liquids and length of soaking can produce different shades. . It takes quite a long time to complete a piece: about one week.
For the cups and teapots .copper has antibacterial properties, and it purifies the water. With copper teapots and sake cups, the copper ions mellow the flavor of the tea and sake.
