I recently had the chance to visit Tsubame Sanjo, a city renowned for its artisanal craftsmanship in Japan. Although the initial purpose of my trip was to visit a Japanese pear farm, I was drawn to the rich heritage of Tsubame Sanjo, particularly in its metalworking. One of the highlights of my trip was discovering a truly unique sake cup—a piece I had been searching for since I first encountered it elsewhere.
These sake cups are designed to transform, revealing intricate designs when filled with cold sake or water, creating a delightful surprise for guests. To my surprise, I learned that these cups had even been praised during the G7 summit in Japan, adding to their prestige and allure.
A Metal Sake Cup with Tin-Coated Copper: A Fusion of Art and Function
The sake cup I found in Tsubame Sanjo is a masterpiece crafted from copper with a tin coating. Its design incorporates seasonal patterns that change color when filled with cold liquids below 16°C. Tin has long been revered in Japan for its qualities in drinkware; it’s believed that "water in a tin vessel does not spoil" and that "tin reduces the harshness of sake." These traditional beliefs highlight the cultural significance of tin-coated drinkware in Japanese hospitality.
Introduced to Japan approximately 1,300 years ago, tin is both rust-resistant and easy to work with, thanks to its low melting point. Today, it remains a popular material for tableware and drinkware due to its ionizing properties, which can purify water and enhance the flavors of beverages. Paired with copper’s excellent heat conductivity, tin-coating, or "tinning," creates a vessel that not only preserves the quality of the drink but enhances the entire sensory experience.
The Tsubame Sanjo Experience: Bringing Seasonal Beauty to the Sake Cup
This sake cup represents a collaboration between Tsubame’s expert metalworkers and pottery artisans from Gifu, each bringing centuries of tradition to the design. The cup celebrates the beauty of each season in Japan, with patterns that come to life when filled with cold sake.
Cherry blossoms bloom in spring,
Fireworks light up in summer,
Leaves shift colors in autumn (Opps, no color....)
All within the confines of this small yet elegant vessel. When you hold the cup and take a sip, the copper’s heat conductivity allows you to feel the refreshing chill of cold sake right through your fingertips and lips.
This element of surprise and seasonal beauty transforms the act of drinking into a moment of celebration, making each sip special. The sake cup is ideal for gifting, enhancing restaurant settings, or enjoying an intimate evening drink at home. It brings the experience of Japanese culture directly to your table, where the transformation of patterns as the temperature drops makes every pour and sip a shared, magical moment.

Care and Usage Notes
To keep this sake cup in optimal condition, here are a few tips:
- Dry After Washing: To prevent any tarnishing, dry the cup thoroughly after each wash.
- Avoid Sunlight: Prolonged exposure to direct sunlight may cause the colors to fade, so store it in a cool, dark place when not in use.
- Safe Discoloration: Any discoloration over time will not affect the taste or safety of your sake.

This journey to Tsubame Sanjo deepened my appreciation for the artistry behind Japanese craftsmanship and the thoughtful details that elevate even the simplest items.
