Junji Tanigawa, president of JTQ, has worked on branding promotions based on the theme of "communicating messages through space." In collaboration with Gyokusendo, a long-established manufacturer of hammered copperware in Tsubame-Sanjo, Niigata Prefecture, and designated an intangible cultural property, the art piece "Hammered Japanese Ware 'Moon'" has been released.

The sharp, shining, clear silver hemispherical design is inspired by the ever-changing phases of the moon. Depending on the angle, the moon changes from full to half to new moon. It can be used as a bottle cooler, flower vase, or interior ornament. Only 100 pieces will be sold worldwide, with a domestic price of ¥450,000.

Gyokusendo was founded in Tsubame-Sanjo, Niigata Prefecture, in 1816. As the only hammered copperware workshop in Japan that has preserved the techniques of hammered copperware for approximately 200 years, it has been designated an intangible cultural property by the Agency for Cultural Affairs and Niigata Prefecture. Tsuiki is a traditional technique in which a single copper plate is hammered out and then shrunk using various sizes of hammers and wooden mallets to create vessels. The greatest appeal of copperware is that it becomes more comfortable to the touch and acquires a refined luster the more it is used, as it is hammered out one by one by artisans. A shop opened in August 2014 on Antique Street in Aoyama, Tokyo.
