Pewterware was first introduced to Japan some 1,300 years ago by envoys from China. Later, during the early part of the Kamakura era (1185-1333), the Zen monk Eisai visited Song-dynasty China and returned with a maker of tea urns. He passed on his skills to local artisans, leading to the establishment of this craft in Japan. However, it was not until the 18th century that a production center was established in Osaka.

Pewter is a very stable metal. It is an ideal material for sake flasks because it does not affect the delicate flavors of the drink. In contrast, the taste of water is actually improved by the ionic action of the metal. It is also particularly suitable for storing tea, which would deteriorate in anything less than an air-tight container due to the high temperatures and humidity of Japan’s summers.
