Japan has the techniques and workshops for making Buddhist altar items and statues one by one by hand, and those techniques are used for the creation of modern art objects or monuments nowadays. They normally create bespoke casting items and collaborate for one time, but this Bridge across is produced as a sustainable product, which might bring the new direction for the casting industry in Japan. The legs are produced by a sand casting manufacturer in Takaoka, Toyama Prefecture. The bronze of Bridge across will be slowly aged over time with thin lacquer finish to protect the shine of the material. This product has the value of change over a long period of time. In most cases, industrial metal table legs are created by bending existing standard-shaped metal pipes for welding. However, the leg of Bridge across is created with the Japanese craft skills of sand casting.
