This is the "Slumbering Sake Ware Series."
From Tsubame City, Niigata – A Town Renowned for Metalworking
This unique sake vessel was crafted by Shinetsu Works Co., Ltd., a company based in Tsubame City, Niigata Prefecture – a region famous for its long tradition of high-quality metal processing. Released in 2020 under their original brand "Three Snow," this product has been gaining attention not only in Japan but also internationally.
Color-Changing Magic – Like Watching a Trick Unfold
The most captivating feature of the “Drowsy Sake Ware” is its magical transformation.
When a cold beverage (below 16°C) is poured into the cup, the illustrations on the surface begin to change color before your eyes—like magic! It’s a mesmerizing effect that adds a touch of wonder to every pour.
Crafted from Copper and Tin – A Beautiful Blend of Form and Function
Made from copper and tin, the cup features a special coating that reacts to temperature changes. Copper is an excellent conductor of heat, so the moment you hold the cup, you'll feel its refreshing chill against your hands and lips.
The tin-plated interior also offers more than just looks. Tin has long been believed to have purifying properties—it’s said that water or alcohol stored in tin vessels tastes smoother and stays fresh longer. This makes it ideal for sake, enhancing its flavor by softening any harsh notes. Of course, it's also perfect for non-alcoholic drinks.
Designs Inspired by the Seasons and Niigata's Beauty
There are currently six designs available in the “Drowsy Sake Ware” series:
・Cherry Blossoms
・Hydrangeas
・Fireworks
・Autumn Leaves
・Snow Camellias
・Koi Carp
One personal favorite is the Fireworks design, inspired by the famous Nagaoka Fireworks Festival in Niigata. When the cup is chilled and the colors change, the fireworks seem to burst to life—it's truly stunning.
You can pick a design to match the season or your mood. Choosing different designs to share among friends or family can make for a fun and unique experience.
Share a Moment of "Slumber Time" with Someone Special
The makers hope this sake cup helps you create a quiet, relaxing moment with those you care about.
For those small, special times around the dining table—pour your favorite drink, watch the illustrations bloom with color, and enjoy a warm conversation with loved ones.
