During the 17th and 18th centuries, cast iron teapots were used all over Japan for boiling water and leftover a charcoal fire to keep it hot. Today the iron "Tetsubin" (also known as Japanese Cast Iron Pots) has an enamel coating inside and is a household necessity. There is a wide range of sizes and unique shapes, making them very popular among collectors. The shapes and decor of the "Tetsubin" are beautiful in their simplicity. They represent an aspect of Japanese culture that captures the spirit of the moment shared by those enjoying tea together.

The pot keeps the tea warm for up to an hour by distributing heat evenly. Cast iron teapots also offer health benefits by adding trace amounts of iron to your diet when you use it.
