Tales of a Century Hammered Tin Guinomi Sake Cup
Estimated Shipping Widget will be displayed here!
This is a guinomi sake cup made of hammered pure tin. This is an enhanced version of a standard product of Seigado, a metalwork studio in Niigata prefecture.
After melting tin into a sheet form, it is hammered into shape using the hammering technique called tsuiki, making the piece seamless.
This product is part of a project launched by Niigata Prefecture under the theme of "Tales of a Century," products to be used for the next 100 years. It is created by an outside designer and aims to coexist with the warmth of craftsmanship and sophisticated design.
Tin was prized as a material suitable for storing water and other liquids because of its ability to purify what is put inside it. It is also suitable for enjoying the taste of alcohol itself since it does not retain any odor.
Delivered in a wooden box, which makes it a perfect gift for your loved ones.

Maker / Brand
Seigado is a tsuiki workshop based at the foot of Mt. Yahiko in Niigata Prefecture, where this copper-hammering tradition took root centuries ago. Working from a single sheet of metal, their artisans develop each vessel through patient, rhythmic strikes, creating seamless forms that feel both precise and alive.
Family-run, the studio’s craftspeople are members of the Nishikata family. Now in its third generation, Seigado is known for masterful techniques and for pursuing original copper hues, such as their signature indigo blue tones. Beyond skill, what stands out is the conviction behind every piece.

Guinomi
Guinomi are a type of sake cup, smaller than a typical Japanese teacup but somewhat larger than other sake cups. They are often used without a sake carafe, with sake poured directly from the bottle.
Guinomi originally held delicacies during Japanese tea ceremonies, but in time came to be used for drinking sake afterward. They have therefore evolved alongside Japan’s unique tea culture.
