COPPER100

COPPER100 is built on a simple idea: don’t stop at “copper is beautiful.” Turn copper’s real behavior—how it carries heat and cold—into value you can feel in everyday cooking.

Take the beer mug. Pour in a cold drink and the entire mug cools quickly, delivering that crisp, refreshing sensation at the lip. It’s a different kind of pleasure compared to glass or ceramics, and one that makes sense the moment you try it.

On the stove, copper’s role shifts to how it spreads heat. Kettles and cookware benefit from quick, even temperature response, helping you cook with a steadier rhythm and a cleaner finish.

The hammered surface (tsuchime) is also part of the brand’s identity—softening reflections, adding texture, and linking appearance to practical handling in a natural way.

Shinko Metal’s headquarters in Tsubame includes a reservation-based showroom where many items are displayed for hands-on viewing and can be purchased on-site.

Copper also changes over time. Patina and natural aging become part of ownership—an invitation to care for tools and enjoy them for years, not seasons.

A Tsubame copperware maker since 1959

Shinko Metal was established in 1959 in Tsubame City, Niigata, producing and selling copper household goods. The lineup spans kettles, cookware, hot-water bottles, graters, drinkware, tea tools, and more—everyday items made in copper.

Thermal performance you can feel

Copper’s high thermal conductivity means the vessel responds quickly: cold drinks chill the mug fast, while cookware and kettles transmit heat smoothly. That immediate “temperature feedback” is a big part of the COPPER100 experience.

Hammered textures with a calm, modern presence

Hammered patterns (tsuchime) add soft reflections and a tactile grip. The surface becomes a quiet design feature while also supporting usability in the hand.

From signature beer mugs to kettles, cookware, and beyond

COPPER100 covers daily scenes: iconic beer mugs, kettles for boiling water, cookware for cooking performance, and even hot-water bottles and kitchen tools—each chosen for where copper’s qualities matter most.
