Handcrafted in Iwate Prefecture, this cast-iron kettle showcases the traditional Nambu arare (hailstone) pattern—densely packed bumps that both conceal scratches and improve grip.
The arare pattern consists of small round bumps, named after hailstones due to their shape. It is widely used today on many Nambu ironware items. This pattern is not only decorative but also helps to hide scratches and provides a better grip.
With a capacity of 0.6L (20.3 fl oz), it’s ideal for serving hot water to family or guests.
Boiling water in the kettle naturally adds a small amount of iron and reduces chlorine, resulting in smooth, great-tasting water.
It is compatible with induction cooktops (IH), making it easy to use in modern kitchens.
Durable and long-lasting, it’s great for everyday use and also makes a thoughtful gift.

Cast Iron Kettles
In Japan, the traditional cast iron kettle known as the tetsubin has long been cherished for both its function and form. It has been valued for its excellent heat retention, due to its thick cast iron body. The inner iron surface absorbs chemicals in tap water, softening the taste and naturally releasing iron.
The tetsubin originated in the 17th century and evolved alongside Japan's tea culture. Among the most renowned production areas is Iwate Prefecture, home to Nambu ironware. These kettles continue to be crafted using traditional techniques while incorporating modern design, making them enduring in use and aesthetically pleasing in contemporary settings.
