Seigado Metalwork

Seigado has a workshop at the foot of Mt. Yahiko in Niigata Prefecture, where high quality copper was discovered about 300 years ago and "Tsuiki'', the technique of hammering copperware has developed since then.

"Tsuiki'' is a metalworking technique that is derived from the words 'hammer' and 'raise', so this process literally means hammering and embossing copperware products. The traces of the hammering, the process of making are left as beautiful patterns on the products.

There's a saying in Japan that things improve with good use, and Seigado's products have a charm that naturally makes us want to take good care of them. 

About Seigado

What is "Tsuiki"?

"Tsuiki" is a type of metal crafting technique that involves hammering. Metal plates such as gold, silver, copper, and tin are hammered, shrunk, burnished, and embossed with large and small hammers and chisels.The process involves many steps and delicate handwork, so it requires a great deal of skill, and there are only a few craftsmen in Japan who can produce first-class metal crafts.

Mr. Ryota Nishikata

What has remained unchanged since I started this job is the feeling of "I really want to make everything!" I want to get even better at what I'm doing now, and I want to make the things I'm making even better. I have never stopped wanting to improve my skills and my products.

One of the traditional techniques of hammered copper ware is to hammer out a spout of kettle and an ear(protrusion) for a handle from a single copper plate. This is a technique that was lost in the past because it was too difficult, but we have revived it. Each time I complete it, I think I have made the best of it, but after a little while, I feel I should have done more. I would like to continue this never-ending challenge.

Mr. Hiroshi Nishikata

The point at which you feel "this is It!" really depends on the person. It depends on variety of factors such as one's taste, living environment, season and climate, as well as the age and health of the user.

Regardless of whether it is a mass-produced item or a handmade item like ours, whether it is expensive or inexpensive, if people choose to use our products when carefully comparing the two, we as craftsmen would be more than happy.

Tin Sake utensils

Tin has been used for more than 500 years as a special material for purifying and preserving water, as it is believed to have properties that make it resistant to water decay.

In recent years, tin sake cups have been attracting attention from "Toji" (chief brewers), and "Kurabito" (brewery workers) as a way to mellow the taste of sake.

The tin is said to soften the unfavorable taste of fusel oil produced during the brewing process, and draws attention as an item to enjoy sake from breweries, liquor stores, and restaurants.Seigado's tin products are mainly manufactured as sake cups. The forged form fits comfortably in the hand, and the beautiful stretch and luster of the finished product, which is hammered many times, makes the time enjoying Sake a special one.


Seigado has been pursuing the coloration and expression of copper materials since its establishment, and has continued to take on the challenge of developing technology to improve quality and make new attempts, while inheriting traditional techniques.Seigado's "indigo blue" and "madder red" colors elegantly and vividly decorate the dining room.
