Product Description

Warm copper tones and a finely textured surface give the Kagayaki beer tumbler its distinctive presence. The tall, gently tapered form catches the light across small facets, bringing depth and character to a simple evening drink.

Made in Tsubame, Niigata, the tumbler pairs a pure copper body with a tin-plated interior. Copper readily takes on the temperature of its contents, so a chilled pour brings a cool sensation to the vessel. It is designed for cold drinks only; its appeal is the immediate feel of the metal, rather than a promise of prolonged insulation.

With a 440 ml capacity (14.9 US fl oz), it offers room for a smaller pour of beer with space for the head. At approximately 7.7 cm across and 13.7 cm high, and weighing 188 g, it has a slender profile with a textured surface to appreciate in the hand. Set it beside understated ceramics or on a wooden tray to let the copper colour stand out.

The tumbler carries Made in TSUBAME certification, identifying its certified production origin in Japan’s metalworking city. Supplied by Tamahashi and presented in a paulownia wood box, it makes a considered gift for a beer enthusiast or someone who enjoys Japanese tableware. One tumbler is included.

Questions About This Piece

Can I use this tumbler for hot drinks?
No. This model is designed for cold drinks only. Copper quickly takes on the temperature of its contents, so hot liquids can make the vessel uncomfortable to hold.

Japanese metalwork · Material, form & finish

The art of metal. The pleasure of everyday use.

In Japan, metalworking has long brought together practical purpose and an eye for beauty. From copper shaped with hammers in Tsubame to vessels cast in Takaoka, regional traditions have given everyday objects a distinctive character.

A tumbler brings that story close: in the curve of its body, the feel of its surface and the way its finish catches the light. Different metals and techniques create different experiences, making the details of each piece worth discovering.

What makes Japanese metal drinkware distinctive?

Japan’s metalworking regions bring different skills to the table. Tsubame is known for metal utensils and copperware; Takaoka has a long casting tradition. Shaping, casting, polishing and surface finishing each contribute to a vessel’s character.

The appeal is in the details: the proportions, the rim, the texture and the finish. The techniques used vary by maker and product, so the story of the individual piece matters as much as its place of origin.

What is the difference between the metal and the finish?

The body is the base metal; the finish is its surface treatment. A copper tumbler, for example, may have a tin-plated interior or a gold- or silver-plated finish. A gold-coloured vessel is not necessarily solid gold, and a silver-coloured vessel is not necessarily solid silver.

Read the body material, interior lining and exterior finish together. This gives you a clearer picture of what you are choosing and how to care for it.

Is every tumbler made by hand?

Methods differ. Some vessels are shaped by repeated hammering; others are cast in moulds or formed with machinery, sometimes followed by hand finishing. A textured surface alone does not establish that a tumbler is hand-hammered.

Look for the specific technique in the product description. Each method offers its own possibilities for shape, precision and surface character.

Will it keep my drink cold, and can I use it for hot drinks?

Construction matters as much as the metal. A single-wall metal tumbler can quickly feel cool when filled with a chilled drink, but this is different from the temperature retention of a vacuum-insulated vessel. Double-wall construction does not automatically mean vacuum insulation.

Use the temperature guidance for the individual product. A tumbler marked for cold drinks only should not be used for hot drinks. Check any restrictions on acidic drinks or prolonged storage too, as these depend on the lining and finish.

How do I choose the right size and feel?

Start with your usual drink and serving size, allowing space for ice or foam. Then compare the height, diameter and weight: two tumblers with the same capacity can feel quite different in the hand.

Consider the rim and surface as well. A slender form, a wider opening and a textured finish each offer a different experience. Use the dimensions and close-up photographs to find a piece that suits your daily ritual.

How should I care for the surface and finish?

Follow the maker’s instructions for the exact metal and finish. Gentle hand washing with a soft sponge and mild detergent, followed by careful drying, is a sensible starting point when permitted by those instructions. Use a dishwasher only when the product is explicitly described as dishwasher-safe.

Some surfaces change in tone with use; others have a coating or deliberately aged finish. Avoid abrasive pads and metal polish unless the maker recommends them, as they can alter plating or remove an intentional surface treatment.
