In Japan, cast iron tea wares have been used for centuries for their practical functionality and alluring shapes. TWG Tea offers a large collection of Japanese teapots and coasters, all made in cast iron, a material known to keep the tea hot longer. All teapots are fully enamelled so that these teapots can be used for all types of tea. Each teapot is handmade in Japan according to ancestral methods to respect traditions, historic shapes and trimmings. Note: This teapot should never be exposed to heat or placed on a stovetop.
